AAstronomy & coordinates
A small apparent shift in direction caused by the observer’s motion and the finite speed of light.
Word origin, evidence & sources
Word origin · etymology
Latin borrowing.From Latin aberratio and aberrare, to wander away. The astronomical use names a displacement from an uncorrected direction.
How we know · epistemology
Physical modelObserver motion and finite light speed explain this directional correction. Its inclusion affects high-precision coordinate comparisons, not the object’s underlying identity or an independently established symbolic meaning.
Horary & traditional technique
Also: accidental fortitude
A planet's traditional condition from chart circumstances—such as house category, motion, and solar proximity—rather than its essential zodiacal dignities. The relevant circumstances and their treatment must be named by the method.
Word origin, evidence & sources
Word origin · etymology
Latin-derived technical phrase.Accidental means circumstantial rather than inherent here; dignity names rank or standing. The phrase concerns chart conditions beyond essential zodiacal status.
How we know · epistemology
Context-dependent traditional evaluationHouse membership, apparent motion, and stated solar separation can be calculated from declared chart conventions. Lilly-style judgments attach traditional testimony to selected circumstances, but no single score, priority order, or automatic yes/no verdict follows from these labels. Essential dignity concerns a planet's zodiacal placement; accidental dignity concerns the circumstances of this chart.
Human Design
Also: activated gate
A planetary position assigned to a Human Design gate; one activation alone does not necessarily define a center.
Word origin, evidence & sources
Word origin · etymology
Latin-derived English noun, technically repurposed.Activation is making active, from active. The chart borrows this wording for the marking of a gate by a planetary placement.
How we know · epistemology
Positional assignment ruleAn activation records that a selected planet falls within a gate sector. It is evidence of that mapping only; determining channels, centers or type requires subsequent graph rules rather than counting the activation as a complete connection.
Gene Keys
The Gene Keys sequence of Life’s Work, Evolution, Radiance and Purpose, used for contemplation of personal foundations.
Word origin, evidence & sources
Word origin · etymology
Modern authored English label.Activation evokes bringing potential into activity; sequence names an ordered series. The title identifies the first Gene Keys pathway.
How we know · epistemology
Four-sphere contemplation structureThe sequence selects four mapped themes as foundations for reflection. Calculations identify the keys and lines, while claims about personal purpose or radiance remain contemplative meanings rather than observed biological or vocational facts.
Human Design centers
Also: Ajna
Human Design’s symbolic center for conceptualization and mental processing, not a neurological assessment.
Word origin, evidence & sources
Word origin · etymology
Sanskrit loanword in a modern compound.Ājñā means command, order, or instruction. The name is borrowed from chakra terminology into the system's chart vocabulary.
How we know · epistemology
Symbolic center correspondenceThis center is associated with concepts and mental processing in the teaching. Its definition is calculated from channels; it cannot establish intelligence, cognitive rigidity or the validity of a person's beliefs.
Indian astrology
Also: Akṣavedāṃśa · Akshavedamsha · D45
The D45 Jyotish chart, derived from 45 portions of each zodiac sign under a declared rule.
Word origin, evidence & sources
Word origin · etymology
Traditional Sanskrit name: akṣavedāṃśa.The final aṃśa means a portion; the forty-fifth division is the attested chart identity. Pañcacatvāriṃśat means forty-five, but that numerical paraphrase does not establish how the older name akṣaveda was coined.
How we know · epistemology
Forty-fifth-part mapping conventionD45 derives another arrangement from the same input longitude rather than collecting new observations. Broad reading scope makes it especially important to record the original question and consider conflicting placements instead of selecting confirming details.

Editorial subject classification“Almanacs, divisions & periods” is a browsing category chosen for this atlas. Its child entries share a topic or practical connection. This grouping is not evidence that all of them descend from one historical lineage; transmission claims require separate sources.
Astronomy & coordinates
Also: solar altitude
An object’s angle above or below the horizon; here this is different from a location’s height above sea level.
Word origin, evidence & sources
Word origin · etymology
Latin through Middle English.Latin altitudo means height, from altus, high. Astronomical altitude preserves this vertical sense as an angle above the horizon.
How we know · epistemology
Local observational geometryAltitude is calculated relative to a local horizon. Atmospheric refraction changes apparent altitude near the horizon, so a geometric result and an observed sighting need not coincide exactly.
Time & location
Also: time fold
A clock reading repeated when clocks move backward; an offset or fold choice is needed to identify the instant.
Word origin, evidence & sources

Maps & directions
Also: planetary angularity line
An astrocartography line marking locations where a selected planet rises, sets, culminates or reaches lower culmination at the reference instant.
Word origin, evidence & sources
Word origin · etymology
Descriptive mapmaking phrase.Angular refers to chart angles; line names the plotted locus where a body meets a specified angular condition.
How we know · epistemology
Locus of an astronomical conditionEach line joins locations satisfying one specified angular condition at a fixed instant. Rising and setting calculations depend on the adopted horizon model; line proximity is a geometric relationship, not a measured dose of planetary influence.
Horary & traditional technique
Also: angular houses · succedent houses · cadent houses
The traditional grouping of houses 1, 4, 7 and 10 as angular; 2, 5, 8 and 11 as succedent; and 3, 6, 9 and 12 as cadent. In a quadrant system, angular houses begin at the chart angles. The grouping is one circumstance in a horary reading.
Word origin, evidence & sources
Word origin · etymology
English terms with Latin antecedents.Angular comes through Latin angularis from angulus, ‘corner’ or ‘angle’. Succedent comes from Latin succedens, the participle of succedere, ‘to follow’ or ‘come next’. Cadent comes from Latin cadens, the participle of cadere, ‘to fall’. These histories explain the positional language, not the origin, validity, or universal interpretation of the astrological house categories.
How we know · epistemology
Chart-relative house classification plus traditional interpretationGiven a stated house system, place, and time, a planet's house membership and its angular, succedent, or cadent category can be reproduced. This is not the same thing as mundane angularity in observational astronomy, which concerns an object's relation to a local horizon or meridian. Lilly-style claims about strength are traditional judgments from this chart circumstance; category membership alone does not establish a result or a universal ranking across schools.
Chinese & East Asian calendars
Also: annual number · annual numbers
The number from 1 through 9 assigned to the effective year by the selected annual Nine Star rule. A different year boundary can change this result near early February.
Word origin, evidence & sources
Word origin · etymology
Descriptive English label; annual has Latin roots.Annual comes through French and Latin forms associated with annus, year. The full phrase is an explanatory label for a yearly Nine Star classification, rather than an established ancient technical expression.
How we know · epistemology
Arithmetic classification under a declared conventionPublished annual examples test the descending cycle. Interpretive qualities need their own attribution; this number alone supplies neither monthly numbers nor directional forecasts.
Timing & comparison
Also: profections · annual profections
A traditional timing method advancing the starting sign by one sign for each completed year of age.
Word origin, evidence & sources
Word origin · etymology
Latin-derived technical phrase.Profection comes from profectio, advancement or going forward; annual specifies the year-by-year advance.
How we know · epistemology
Historical timing ruleCompleted age determines a repeated twelve-sign count under the chosen starting point. The calculation can be checked arithmetically; interpreting the activated sign as a year’s events is an additional claim.

Also: antar-dasha · bhukti
A subperiod within a major dasha period; dates depend on the selected system and year-length convention.
Word origin, evidence & sources
Word origin · etymology
Sanskrit compound: antardaśā.Sanskrit antar means within or between; daśā means period in Rao’s usage. Antardaśā thus suggests an inner period. The compound analysis does not date the technical term’s origin.
How we know · epistemology
Nested period arithmetic and attributed chart interpretationArithmetic nesting and astrological interpretation answer different questions. The first locates a selected date in a timetable; the second proposes traditional meaning. Neither a shorter interval nor a more detailed display supplies evidence that a life event will occur. Missing natal positions prevent a placement reading. Missing chart conditions prevent a complete traditional judgment. Show these gaps explicitly, including when both period lords are the same.

Astronomy & coordinates
A direction corrected for observational effects such as aberration and gravitational light deflection; the precise correction set must be specified.
Word origin, evidence & sources
Word origin · etymology
Descriptive astronomical phrase.Apparent means appearing to an observer. The label concerns the observed-looking direction after specified corrections, not a claim that it is illusory.
How we know · epistemology
Observational modelThe direction includes specified light-propagation and observer-motion corrections. “Apparent” is a technical model choice; the value is comparable only when the other calculation includes the same effects.
Aspects & angular relationships
An aspect currently moving toward exactness, judged from the bodies’ relative motion; a later station can interrupt it.
Word origin, evidence & sources
Word origin · etymology
Descriptive participial phrase.Applying uses apply in the older sense of drawing toward or bringing together; the aspect is moving toward exactness.
How we know · epistemology
Local motion testRelative motion shows whether a contact is approaching exactness at that instant. A later station or change of direction can interrupt it, so application alone does not establish future completion.
Zodiac signs

Horary & traditional technique
Also: astrological bound · astrological bounds · terms (astrology)
In traditional astrology, one of the unequal degree-ranges within a zodiac sign whose assigned ruler is determined by the selected bounds (terms) table.
Word origin, evidence & sources
Word origin · etymology
Bound in the sense of a limit comes through Middle English and early French bodne, from Latin bodina. The alternative technical word term is associated with Latin terminus, boundary.These are distinct word histories for two labels used in astrology. Their shared boundary sense does not establish the date or route by which a particular dignity table acquired either technical name.
How we know · epistemology
Historical table-based classificationA bound ruler is a result of placing an unrounded zodiacal degree in a named table's interval. Historical tables differ, so the interval convention and source must accompany the result; the label is not a measured property of a planet or evidence for a personal outcome.

Horary & traditional technique
A traditional condition in which a planet is judged to be too near the Sun under a named rule, commonly distinguished from an exceptionally close cazimi conjunction and from the wider area called under the beams.
Word origin, evidence & sources
Word origin · etymology
Middle English combustioun, through Anglo-French and Late Latin combustio, from comburere, to burn up.The noun records a burning metaphor. Its astrological use does not imply that a planet is physically consumed or establish the validity of a solar-proximity interpretation.
How we know · epistemology
Solar-proximity classification in a traditional methodThe observable input is a Sun-planet separation in a declared coordinate convention. A method must also declare its boundaries and any cazimi exception before assigning combustion.

Word origin · etymology
Greek through Latin.From Greek ekleiptikos, relating to an eclipse. The celestial path is named for the eclipses occurring near it.
How we know · epistemology
Astronomical geometryEarth’s orbital geometry supplies the reference plane. Its orientation depends on the epoch and model; it is a coordinate reference, not a physical band carrying zodiacal qualities.
Astronomy & coordinates
Also: latitude_deg
An object’s angular distance north or south of the ecliptic, distinct from geographic latitude.
Word origin, evidence & sources
Word origin · etymology
Classical roots in an English compound.Latitude comes from Latin latitudo, breadth. Here that breadth is angular distance north or south of the ecliptic.
How we know · epistemology
Astronomical geometryThe coordinate follows from an object’s direction relative to the ecliptic plane. It can distinguish objects sharing a longitude; it should not be read as geographic latitude or personal temperament.

Coordinate conventionThis angle can be reproduced from a position and a declared zodiac origin. A different origin changes the number without moving the object; longitude alone omits latitude and distance.
Calculation concepts
Also: effective years
The year selected for a calculation after its year-boundary rule has been applied. In the fixed February 4 method, a date before February 4 uses the preceding Gregorian year.
Word origin, evidence & sources

Word origin · etymology
Greek through Latin.Greek ephemeris meant a diary or daily record; astronomical tables preserve the idea of positions recorded day by day.
How we know · epistemology
Numerical astronomical modelAn ephemeris predicts positions from fitted observations and dynamical models. Agreement with independent observations tests the positional calculation, while its date range and model assumptions limit accuracy.
Research & interpretation
The philosophical study of knowledge, justification and the limits of evidence. Here, a term’s epistemology explains how its claims are supported; etymology instead concerns the origin and history of a word.

Word origin, evidence & sources
Word origin · etymology
Descriptive English method name.Equal identifies the repeated equal angular size of the houses. The name describes their division rather than a founder.
How we know · epistemology
Geometric division conventionThe usual construction spaces boundaries thirty degrees from the Ascendant. This makes cusp arithmetic simple, but does not prove that equal sectors correspond to equal or measurable life influences.

Historical evaluative conventionSpecified tables assign dignity from zodiacal position. Alternative tables can produce different scores, so the source matters; these scores describe traditional suitability or standing, not measured force, moral worth or a person's intrinsic value.
Research & interpretation
Also: word origin
The study or account of a word's history: its earlier forms, meanings, related words and passage between languages.
Word origin, evidence & sources
Word origin · etymology
English received the word through French and Latin from Greek etymologia.The Greek formation joins etymon, a word's original or literal sense, with -logia, study or account. Etymon is related to etymos, ‘true’; this historical naming does not make a word origin proof of a belief.
How we know · epistemology
Historical linguistic evidenceAn etymology is supported by recorded usage, comparison and linguistic analysis. A word's older meaning does not determine every modern use or establish the truth of an astrological claim; uncertain derivations should remain labelled uncertain.

An instant when a moving body's longitude reaches a declared aspect angle from a fixed natal target, within the solver's stated numerical tolerance.
Word origin, evidence & sources
Word origin · etymology
Descriptive English phrase with Latin-derived vocabulary.Exact comes from Latin exactus, associated with examining or measuring; transit from transitus, passage. The phrase names a specified angular passage precisely located in time.

Word origin · etymology
Latin-derived noun.From exaltare, to lift high, with altus, high. The traditional dignity name uses a metaphor of elevation.
How we know · epistemology
Historical dignity assignmentThe designation expresses an inherited evaluative rule, not physical height above the horizon. Its symbolic status cannot establish superior character or override the other conditions in a chart.
FHorary & traditional technique
Also: faces · decanal face · decanal faces
A traditional ten-degree division of a zodiac sign used as a minor essential dignity in a specified astrological table; it is also called a decan in this zodiacal sense.

Word origin · etymology
Latin facies, ‘form, appearance, or face.’The Latin lexical sense supports the English word's ancestry. The supplied sources do not establish a complete transmission history from facies to this astrological technical sense, so that history is left open.
How we know · epistemology
Historical zodiacal subdivision and rulership conventionWithin this use, a face follows a declared ten-degree zodiac partition and table.

Initialism of three researchers' surnames.GMT stands for Goodman–Martínez–Thompson: Joseph Goodman, Juan Martínez-Hernández, and J. Eric S. Thompson. Here it does not mean Greenwich Mean Time.
How we know · epistemology
Chronological alignment conventionA correlation constant links the Long Count to Julian day numbering. This implementation declares 584283; differing correlation choices shift converted dates, so agreement on the count alone is insufficient when comparing historical chronologies.
Jyotish & timing
Also: Gochar · Gochaara · Gocara
Jyotish transit analysis: moving grahas read against natal reference points, including Moon and Lagna.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: gocara.Gocara originally denotes a cow's range or pasture, hence a range or field of action; astronomical usage applies it to planetary positions and relationships.
How we know · epistemology
Named transit-reading conventionSeparate natal-reference charts make the counting rule explicit. A sign count establishes a relationship in that model; further judgement requires the chosen method's additional rules.
Gene Keys
The Gene Keys sequence framework for contemplating purpose, relationships and contribution; it is a teaching path, not a fate calculation.
Word origin, evidence & sources
Word origin · etymology
Modern authored English title.Golden evokes value or excellence; path evokes a course of development. Gene Keys uses the combined metaphor as a curriculum name.
How we know · epistemology
Structured contemplative curriculumThe sequence organizes reflection across purpose, relationships and contribution. Its order belongs to a teaching method; completing the path does not mathematically determine a life outcome or verify the profile's descriptions.
Indian astrology
Also: grahas
An astrological “planet” or seizer; the classical nine include the Sun, Moon and lunar nodes, not only physical planets.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: graha.Graha means a seizer or grasper, from grah, to seize; its celestial use includes entities beyond the modern astronomical category planet.
How we know · epistemology
Traditional classificationThe category groups bodies and calculated nodes by their roles in Indian interpretation. Calling something a graha identifies that traditional role; it does not assert that every member is a physical planet.
Jyotish & aspects
Also: Graha Drishṭi · Graha Drishti aspects
Planetary aspects in Jyotish, with directional relationships determined by the graha; distinct from rashi drishti.
Word origin, evidence & sources
Word origin · etymology
Sanskrit compound: graha-dṛṣṭi.Graha means planet or seizer and dṛṣṭi seeing or sight. The compound uses the traditional metaphor of a planet's gaze.
How we know · epistemology
Traditional aspect ruleA displayed sign relationship does not measure physical force or establish degree-based strength. Node rules and additional judgement require an explicit convention.
Catalogue & galactic terms
An extended concentration of matter associated with large-scale galaxy motions, represented in this catalogue by a selected reference direction.
Word origin, evidence & sources
Word origin · etymology
Modern descriptive astronomical name.Attractor describes gravitationally inferred attraction and great its scale. The name is an observational label, not a mythological proper name.
How we know · epistemology
Large-scale astronomical structureThe name concerns a broad concentration of matter studied through galaxy motions. A catalogue point is a chosen representative direction, not the complete structure; a narrow astrological orb must not be mistaken for its physical extent.
Maps & directions
A circle dividing a sphere into equal halves; spherical local-space maps extend a planetary direction along such a path.
Word origin, evidence & sources
Word origin · etymology
Traditional descriptive geometric phrase.Great identifies the largest circle cut from a sphere: its plane passes through the sphere's center.
How we know · epistemology
Spherical geometryOn a sphere, a great circle follows a plane through the center and can extend a chosen local direction. Antipodal points leave the route ambiguous without a bearing; the model also approximates Earth's actual ellipsoidal surface.
Time & location
Also: Gregorian
The civil calendar used by this form; its leap-year rule differs from the older Julian calendar.
Word origin, evidence & sources
Word origin · etymology
Eponym.Named after Pope Gregory XIII, who promulgated the calendar reform in 1582. Gregorian is the adjectival form of his name.
How we know · epistemology
Civil calendar conventionGregorian arithmetic follows a defined leap-year rule. Historical documents did not adopt it everywhere at once, so a correctly calculated proleptic date may differ from the date originally recorded.

Word origin, evidence & sources
Word origin · etymology
Astrological name Gulika combined with Sanskrit kāla, time.The compound names Gulika’s period. The historical timing text establishes the technical use; it does not establish a derivation of the name from the separate Sanskrit word for a small ball.
How we know · epistemology
Traditional planetary allocation of daylightKalaprakasika does not classify this period as inauspicious. Other applications differ; the displayed interval must not be confused with a separately calculated Gulika or Mandi point in a horoscope.
HMaya & Mesoamerican calendars
Also: Haab’
A 365-day Maya calendar with eighteen twenty-day months plus a five-day period.
Word origin, evidence & sources
Word origin · etymology
Yucatec Maya calendrical name.Haab, also written Haab’, names the solar-year calendar. Its language form is retained rather than replaced by the English calendar label.
How we know · epistemology
Historical solar-year countThe month structure defines a 365-day sequence that can be converted using a chosen correlation. Its year is not identical to the tropical year, so seasonal alignment cannot be assumed constant merely from the label solar calendar.

Human Design
Also: hanging gates
An activated Human Design gate that is alone in its prescribed channel because its harmonic partner gate is not activated in the selected chart view.
Word origin, evidence & sources
Word origin · etymology
Descriptive modern English compound used in Human Design.Hanging modifies gate in an image of an endpoint left without its paired connection. The sources document the current technical phrase; no claim is made for an ancient or non-English origin.
How we know · epistemology
Graph-derived endpoint stateThis label records one active endpoint and an inactive harmonic partner under the selected birth/design graph and node convention. It can be audited from the endpoint ledger. It does not show that a person lacks something, needs another person, or will have a particular emotional or relational experience.

Derived charts & points
Also: harmonics · harmonic factor
A derived longitude display: multiply each selected ecliptic longitude by an integer h and reduce it modulo 360°. A conjunction in that display corresponds to an angular relation near k/h of a circle; its reduced order must be checked before attaching a factor-specific teaching.
Word origin, evidence & sources
Word origin · etymology
Mathematical and musical vocabulary borrowed into modern astrology.Harmonic derives through harmony from Greek harmonia, joining or agreement. In chart practice the name points to integer proportional divisions of the circle; it does not identify a measured acoustic or electromagnetic frequency.
How we know · epistemology
Reproducible angular transformation plus school-specific interpretationInteger multiplication and circular reduction are arithmetic. An interpretation requires a named school. The study themes offered here concern prominent multi-planet patterns; a qualifying pair alone does not establish the study’s pattern selection, a personality trait or a forecast.

Harmonics & patterns
Also: transformed orb
Angular deviation measured in the ; near the selected exact aspect, divide by h to recover the corresponding natal deviation.
Word origin, evidence & sources
Word origin · etymology
Modern mathematical and astrological compound.Harmonic identifies the transformed circle; retains the surrounding-circle or allowable-range sense. The phrase specifies tolerance in that harmonic frame.
How we know · epistemology
Scaled angular toleranceMultiplication by the harmonic number scales a nearby natal deviation, so transformed orb divided by that number gives the local natal equivalent. Comparisons require declaring which space supplies the tolerance; a larger search can otherwise create misleadingly numerous matches.
Harmonics & patterns
Also: harmonic three-planet pattern
Cochrane uses this for three planets mutually aspected in one harmonic. In Atlas's selected graph, it means a three-node clique: each of the three pair edges passes the declared factor and orb test.
Word origin, evidence & sources
Word origin · etymology
Middle English through Anglo-French, from Latin triangulum, neuter of triangulus ('triangular'), from tri- plus angulus ('angle').Harmonic modifies this geometric word to name a pattern in a selected transformed circle.

Human Design’s symbolic inspiration and questioning center; its chart status does not measure the brain.
Word origin, evidence & sources
Word origin · etymology
Descriptive anatomical metaphor.Head is the inherited English name for the upper body part. The chart places its pressure-center symbol at the head position.
How we know · epistemology
Symbolic center correspondenceHuman Design assigns inspiration and questioning to this part of its graph. Channel rules determine its status, but that status does not measure brain activity or establish how often a person experiences ideas or uncertainty.
Chinese & East Asian calendars
Also: Heavenly Stems
One of ten labels paired in sequence with the twelve Earthly Branches to form a sixty-step cycle.
Word origin, evidence & sources
Word origin · etymology
English translation of Chinese tiāngān, 天干.Heavenly renders tiān and stem renders gān. The plant-like English name identifies one set of the traditional stem–branch pairing.
How we know · epistemology
Historical cyclical notationThe ten stems form an ordered calendar vocabulary whose sequence can be checked. Their phase and polarity correspondences are traditional classifications, not observations of ten distinct forces acting on a birth.
Astronomy & coordinates

In BaZi, a Heavenly Stem listed within an Earthly Branch rather than shown as that pillar’s visible upper stem.
Word origin, evidence & sources
Word origin · etymology
Chinese cánggān 藏干: cáng means ‘store, conceal’ and gān is the shortened form of tiāngān, ‘Heavenly Stem.’The literal sense describes the conventional placement of a stem within a branch. This entry does not assert a single date, author or universal origin for the membership tables used by later schools.
How we know · epistemology
Traditional BaZi chart convention and interpretive inputA hidden stem is a stated member of a branch under a source table; it is not a measured quantity or an automatic prediction. Traditional texts compare stems concealed in branches with the day stem, but any judgment about strength, roots, seasonal command, combinations or future events requires additional named rules.

A Jyotish divisional chart based on the two halves of each zodiac sign.
Word origin, evidence & sources
Word origin · etymology
Greek loan into Sanskrit: horā.Monier-Williams identifies horā as borrowed from Greek and records hour, half-sign and horoscopy senses. Here it names the half-sign chart; a planetary hour is a different application of the same word.
How we know · epistemology
Declared Hora constructionThe half-sign assignment can be checked against the source longitude. A Sun/Moon division does not uniquely settle how every school draws a Hora chart; the two-sign construction must be named. Neither its geometry nor its lexical history verifies a life interpretation.

Latin-derived labels alongside Sanskrit.Horary derives from hora, hour; interrogation means asking; praśna means question. The combined title links several traditions' question-based vocabulary.
How we know · epistemology
Question-based judgment in distinct traditionsLilly weighs significators, dignities and aspects in Western question charts. Rao describes Tajaka combinations used in Prashna, an Indian approach with its own conventions.

Astronomy & coordinates
An object’s angular position relative to the observer’s meridian; it changes as Earth rotates.
Word origin, evidence & sources
Word origin · etymology
Descriptive astronomical compound.Hour records the traditional time-like division of rotation; angle names the angular separation from a meridian.
How we know · epistemology
Earth-rotation geometryThe angle combines Earth’s orientation with an object’s celestial direction. Its value is local and time-dependent; a longitude measured from the zodiac origin cannot substitute for it.
Houses & angles
Also: astrological house
One of twelve chart divisions used for life topics. The boundaries depend on the chosen house system.
Word origin, evidence & sources
Word origin · etymology
Inherited English word used metaphorically.House originally names a dwelling. Astrology applies the dwelling or place metaphor to chart divisions assigned topics.
How we know · epistemology
Traditional division conventionHouse systems partition a chart by different geometric rules and assign topics to those divisions. A precise cusp calculation validates that chosen construction, not the universal truth of its life-topic assignments.
Houses & angles
Also: cusp
A house boundary in the selected system; being near a cusp does not by itself create a blended zodiac sign.
Word origin, evidence & sources
Word origin · etymology
English compound with Latin-derived cusp.Cusp comes from cuspis, point. A house cusp is the marked boundary or beginning point of a house.
How we know · epistemology
System-dependent boundaryA cusp is reproducible only after a house method is chosen. A planet can change house when the method changes without changing its sky position; boundary proximity should be reported explicitly.
Timing & comparison
Also: cross-chart house placement
A placement of one chart's body within another chart's houses; the receiving chart supplies the house boundaries.
Word origin, evidence & sources
Word origin · etymology
A descriptive English name combining astrological house with overlay, the act of placing one image or layer over another.House descends from Old English hūs. In this technical phrase, overlay names the superimposition of one chart on another; the sources do not establish who first coined the complete expression.
How we know · epistemology
Directional chart comparisonThe selected house convention and receiving birth time determine the placement. Its life topic is an interpretive prompt; reversing the charts usually changes the overlay.

Word origin · etymology
Latin-derived English noun, technically repurposed.Definition comes from defining or setting boundaries. Human Design reuses the word for the connectivity of completed channels.

Also: Profile
A pair of line numbers from the birth and design Sun placements, such as 4/6, linked to the system’s role descriptions.
Word origin, evidence & sources
Word origin · etymology
French/Italian-derived English noun, repurposed.Profile originally describes an outline or side view. Here the word names the paired line designation used as a character outline.
How we know · epistemology
Paired line classificationTwo Sun-line assignments produce the profile pair, using birth and design positions. Small changes near line boundaries can change the label; role descriptions attached to the pair are interpretive themes rather than biographical observations.
Human Design
Also: Type
A category derived from BodyGraph connections; this engine distinguishes Manifesting Generator within the Generator family.
Word origin, evidence & sources

Modern school name with a descriptive qualifier.Uranian identifies the Uranian astrological school; hypothetical marks its proposed points. The phrase does not describe a confirmed body orbiting Uranus.
How we know · epistemology
Unconfirmed mathematical modelThe Hamburg School uses prescribed hypothetical orbits to supply these chart points. Software can reproduce their positions, but that agreement does not constitute an astronomical detection or establish that the proposed planets physically exist.

Indian astrology
Also: Jyotiṣa · Vedic astrology
Indian astronomical and astrological traditions; the label covers multiple schools rather than one universal calculation recipe.
Word origin, evidence & sources

Sanskrit transliteration: jyotiṣa.Derived from jyotis, light or a heavenly light. Jyotiṣa names the traditional discipline concerned with celestial lights and their reckoning.
How we know · epistemology
Historical traditions and calculationTexts and practitioners document several Indian systems of calendrics, astronomy and interpretation. A reliable almanac calculation supports its dates and positions; it does not independently establish the accompanying judgments about life events.

Indian astrology
Also: kāraka
A significator: a planet or other factor assigned to represent a topic under a specified Indian astrological rule.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: kāraka.Kāraka means maker, doer, or producer, from kṛ, to do; in astrology it supplies the language of a significator.
How we know · epistemology
Contextual symbolic assignmentA planet represents a topic because a specified rule assigns that role. Fixed and variable significator schemes need not agree; the assignment should be shown explicitly rather than treated as a physical property of the planet.
Indian astrology
Half a tithi, spanning 6° of Moon–Sun longitude difference; traditional names follow a repeating and fixed sequence.

Jyotish · lunar mansions
Also: Krttika · Kṛttikā · Krittikas · कृत्तिका
The 3rd lunar mansion in the modern Ashwini-first 27-division sequence. Its Sanskrit name also belongs to a historical named asterism; the atlas locates the Moon in an equal sidereal longitude sector.
Word origin, evidence & sources
Word origin · etymology
Sanskrit kṛttikā, grouped with the cutting root kṛt.Monier-Williams places kṛttikā under the kṛt family for cutting and identifies the Kṛttikās as the Pleiades. “Cutters” is a concise interpretive rendering of that connection; the historical name also denotes the mythic group, not merely an adjective.
How we know · epistemology
Lexical attestation, ritual tradition and a stated coordinate conventionThe dictionary attests the Pleiades name and flame or blade representations; the hymn pairs the mansion with Agni. These are historical associations. They do not make every person or interval in this sector destructive or purifying.

Jyotish & relationships
Also: Kuta comparison
Traditional Indian relationship-comparison schemes that evaluate named factors, commonly using the two natal Moons; rules and scoring vary.
Word origin, evidence & sources
Word origin · etymology
Kuta represents Sanskrit kūṭa (कूट), used as a technical name for a factor in traditional horoscope matching.Monier-Williams records senses including a peak, heap or multitude. Those literal senses do not establish why the matching term arose; here its technical use is documented separately in the Jyotish manual.
How we know · epistemology
Traditional matching conventionsA score summarizes the chosen scheme, not a measured probability of relationship success. Sign counts or graha drishti alone do not constitute Kuta matching; the studio does not calculate it.
LIndian astrology
The Ascendant in Indian astrology, usually expressed in the chosen sidereal zodiac.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: lagna.Lagna means attached, fixed, or adhering; in astronomy and astrology it names the ascendant and a significant moment.
How we know · epistemology
Local geometry in an Indian frameworkThe rising ecliptic point is calculated from an instant and location, then expressed in a selected zodiac. Its house and life-topic roles require additional Indian rules, and uncertain birth time can change them.
Indian astrology
Also: Lahiri
A widely used Indian sidereal reference convention; selecting it changes zodiac longitudes, not the physical sky.
Word origin, evidence & sources
Word origin · etymology
Eponym plus Sanskrit technical term.Lahiri names N. C. Lahiri, associated with the Indian calendar-reform convention; ayanāṃśa names the offset. The surname is left untranslated.
How we know · epistemology
Named sidereal conventionLahiri provides a shared reference for comparing many Indian calculations. Its widespread adoption establishes a convention, not evidence that this origin yields more accurate personality readings than other sidereal origins.
Calendar conventions
Also: intercalary month
An additional month inserted by a calendar’s intercalation rules. Chinese and Tibetan calendars determine and label it with their own rules; an inserted month is different from a repeated Tibetan lunar day.
Word origin, evidence & sources
Word origin · etymology
Descriptive English calendar phrase; intercalary is a Latin-derived synonym.Leap month is the English label for an inserted calendar month; its exact coinage is not established by these sources. Intercalary comes from Latin intercalarius, related to intercalare, inserting a day or month into a calendar.
How we know · epistemology
Calendar intercalation ruleAn extra month follows the selected calendar’s alignment and numbering rules. In the Phugpa method implemented here the leap occurrence precedes the regular month of the same number; that ordering must not be transferred automatically to another tradition.
Time & location
An adjustment to UTC used to keep civil time close to Earth-rotation time; it is unrelated to a leap day.
Word origin, evidence & sources
Word origin · etymology
Descriptive extension of leap terminology.The existing leap-day metaphor was extended to a one-second adjustment of civil time; second names its size.
How we know · epistemology
Timekeeping conventionLeap seconds are administrative adjustments linked to Earth-rotation monitoring. Their presence must come from the applicable time standard and date, rather than a repeating rule inferred from calendar leap years.
Zodiac signs
The zodiac sign spanning 120° up to 150° from the selected zodiac’s origin; constellation boundaries differ.
Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.Leo means lion; the sign retains the constellation's animal-name.
How we know · epistemology
Zodiac convention with traditional symbolismLeo is the fifth equal sector and is traditionally fixed fire. The sign uses a defined longitude interval rather than a boundary traced around the Lion constellation; interpretations of confidence or visibility require a separate evidential step.
Zi Wei Dou Shu
Also: Lian Zhen · 廉貞
A principal Zi Wei chart star that Sean Chan describes through the tension between principles and emotional intensity.
Word origin, evidence & sources
Word origin · etymology
Chinese 廉貞; Chan explains 廉 as upright or incorruptible. His “Reformer Star” title is an interpretive epithet.Do not read “Reformer” as a literal translation of 廉貞. A full compound derivation and first specialist use remain unverified.
How we know · epistemology
Contemporary explanation of traditional chart symbolism.The traditional tension does not establish ethical character, relationship conduct or an emotional condition.
Zodiac signs
The zodiac sign spanning 180° up to 210° from the selected zodiac’s origin; constellation boundaries differ.
Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.Libra names a balance or weighing scales, the figure retained by the sign.
How we know · epistemology
Zodiac convention with traditional symbolismTropical Libra begins at the September equinox and is traditionally cardinal air. The equinox fixes an astronomical reference; the scales imagery and readings about balance or partnership do not themselves provide evidence about a person's relationships.
Chinese & East Asian calendars
Also: Li Chun · Beginning of Spring · Lìchūn · Risshun · Start of spring · 立春
The solar term at 315° apparent solar longitude, called Lìchūn in Mandarin and Risshun in Japanese. Choosing this instant as an astrological year boundary is a separate method convention.
Word origin, evidence & sources
Word origin · etymology
Mandarin Lìchūn and Japanese Risshun: readings of 立春.The shared calendrical name is translated Beginning of Spring or Spring Commences. NAOJ records the Japanese reading りっしゅん. These are different language readings of a seasonal term, not evidence that all associated divination methods share identical rules.
How we know · epistemology
Astronomical marker and boundary choiceAstronomy fixes the 315° instant; local time conversion supplies its civil date. An annual divination method may instead use a fixed February 4 boundary. Retain that distinction, and do not treat this seasonal label as a local-weather observation.
Gene Keys
Also: Life's Work · Brand sphere
The Gene Keys sphere mapped to the birth Sun’s key and line, used as a symbolic contemplation focus.
Word origin, evidence & sources
Word origin · etymology
Transparent English possessive phrase.Life's Work names the work of a lifetime; Brand is the system's alternative sphere label, borrowing modern public-identity vocabulary.
How we know · epistemology
Birth-Sun symbolic assignmentThe birth Sun's gate and line determine this sphere under the profile's map. The resulting theme may support reflection on expression and contribution; it does not identify an objectively correct career or a required life mission.
Astronomy & coordinates
Allowance for the time light takes to travel from an object to the observer.
Word origin, evidence & sources
Word origin · etymology
Descriptive English compound.Light-time is the time light needs to travel; correction names the adjustment for receiving a body's earlier light.
How we know · epistemology
Physical modelFinite light travel means an observed direction relates to an earlier emission event. The correction belongs to positional astronomy; it does not introduce an astrological delay in someone’s experience.
Human Design
Also: gate line
One of six divisions within a Human Design gate; it is an angular subdivision rather than a physical line on the body.
Word origin, evidence & sources
Word origin · etymology
Latin through French; translated diagram term.Line comes from linea, linen thread or line. Its system use inherits the six-line structure of an I Ching hexagram.
How we know · epistemology
Nested symbolic subdivisionThe gate is divided into six equal angular parts, with each part assigned a line theme. This makes the number calculable; the theme's fit to a person is not established by the precision of the subdivision.
Time & location
Also: true solar time · apparent solar time
Time reckoned from the actual Sun’s daily position, differing from mean solar time by the equation of time.
Word origin, evidence & sources
Word origin · etymology
Descriptive astronomical phrase.Local specifies the place and apparent refers to the observed-looking Sun. The wording distinguishes sundial-like time from a mean-Sun clock.
How we know · epistemology
Apparent solar clockThe Sun's actual apparent position determines this time scale. It differs seasonally from a uniform clock, so a conversion needs the equation of time as well as longitude rather than only a timezone offset.
Astronomy & coordinates
Also: local horizons
The observer’s horizontal reference plane, perpendicular to the local vertical; in horizon coordinates it supplies the zero level for altitude.
Word origin, evidence & sources
Word origin · etymology
Latin-derived modifier and Greek-derived noun.Horizon comes from Greek horizōn, bounding or defining. Local specifies the observer's own dividing plane between visible and hidden sky.
How we know · epistemology
Observer-based coordinate referenceThe reference depends on the observer’s position. A calculated zero-altitude direction belongs to this idealized frame; it does not describe every obstruction in the visible skyline.
Time & location
Also: mean solar time
A clock based on a uniformly moving mean Sun at the location’s longitude; it omits legal timezone and daylight-saving rules.
Word origin, evidence & sources
Word origin · etymology
Descriptive astronomical phrase.Local specifies one longitude, mean specifies an averaged Sun, and solar identifies the Sun as the time reference.
How we know · epistemology
Longitude-based clock conventionLongitude sets the offset of a uniform solar clock from Greenwich. This can reproduce a stated historical time basis, but it does not include legal timezone changes or daylight saving and must not be substituted silently for civil time.
Location techniques
Also: local space
A locational method mapping the horizon directions of bodies from a chosen place, rather than only zodiac longitudes.
Word origin, evidence & sources
Word origin · etymology
Modern descriptive English method name.Michael Erlewine called his birthplace-centered map the astrology of local space. The wording emphasizes the surrounding horizon and directions.
How we know · epistemology
Horizon geometry with symbolic mappingA body's azimuth at a specified place and instant provides a direction projected onto a map. That direction depends on the observer and projection convention; it is not evidence of a physical influence traveling along the drawn route.
System gateways
Locational astrology predates its modern computerized maps.
Word origin, evidence & sources
Word origin · etymology
Descriptive location vocabulary and modern method names.Locational and relocation name place and changing place; Astro*Carto*Graphy is Jim Lewis's coined title; local space is Michael Erlewine's surrounding-space label.
How we know · epistemology
Observer geometry and locational interpretationRelocation keeps the instant and changes local axes; astrocartography maps angular positions, while local-space maps observer-based directions. Changing zodiac labels alone cannot move physical map lines. These geometries are testable; promises about a location’s personal effects are interpretive claims.

Maya & Mesoamerican calendars
A Maya system counting days through units including k’in, uinal, tun, katun and baktun; correlation links it to other calendars.
Word origin, evidence & sources
Word origin · etymology
Descriptive English scholarly label.Long distinguishes a continuing count of elapsed days from shorter repeating calendar cycles; count names its chronological tally.
How we know · epistemology
Historical day-count notationThe units record elapsed days from an epoch rather than a recurring birthday category. Converting to another calendar requires a stated correlation; interpretation of an inscription also needs its historical and linguistic context.
Calculation concepts
Also: longitude_speed_deg_per_day
How quickly ecliptic longitude is changing, in degrees per day; negative values indicate retrograde motion in that frame.
Word origin, evidence & sources
Word origin · etymology
Descriptive mathematical compound.Longitude identifies the angular coordinate; speed identifies its rate of change. This label does not mean linear travel speed.
How we know · epistemology
Derived astronomical quantitySpeed is the time derivative of longitude in the chosen frame. A negative value describes that coordinate’s motion; changing the origin or frame can change its interpretation.
Timing & comparison
Also: annual lord · annual time lord
In annual profections, the traditional ruler of the zodiac sign reached by the completed-age count. Other timing methods assign their own time lords.
Word origin, evidence & sources
Word origin · etymology
English descriptive phrase with an Old English root.Lord descends from Old English hlāford, associated with hlāf (loaf) and weard (keeper). Here the title is a metaphor for a planet’s assigned authority over a year; this does not establish the first use of the technical phrase.
How we know · epistemology
Traditional timing and rulership conventionThe annual lord follows a reproducible count and rulership table. Its symbolic authority is an interpretive premise, not a physical force or demonstrated predictor of events.

Tibetan calendars
Also: lo gsar · Tibetan New Year
A Tibetan name for New Year, observed through different calendars and customs across Himalayan communities. A Phugpa Losar calculation identifies one named calendar’s year boundary.
Word origin, evidence & sources
Word origin · etymology
Tibetan lo gsar: lo, year, and gsar, new.The compound means new year. Its shared name does not make every community’s date or observance identical.
How we know · epistemology
Cultural observance and school-specific calendar boundaryHistorical and contemporary accounts document several Losar traditions. Calculating the first civil day of a Phugpa year does not determine all regional New Year festivals.
Derived charts & points
Also: Part of Fortune · Fortune
An angular point combining Ascendant, Sun and Moon. Common traditional formulas reverse the Sun–Moon order for night births.
Word origin, evidence & sources
Word origin · etymology
Traditional translated name.Lot means an allotted portion or a share; Fortune names the associated traditional topic. It is not the name of a physical body.
How we know · epistemology
Traditional angular formulaThe point comes from a specified Ascendant–Sun–Moon formula and day/night rule. Different conventions can yield different positions; its name is not evidence of wealth, luck or a promised outcome.
Derived charts & points
Also: Part of Spirit
A traditional Ascendant–Sun–Moon combination complementary to Fortune under commonly used day/night formulas.
Word origin, evidence & sources
Word origin · etymology
Traditional translated name.Lot retains the sense of an allotted portion; Spirit supplies this lot's conventional topic. The wording describes symbolic assignment.
How we know · epistemology
Traditional angular formulaSpirit is calculated through a named formula, often complementary to Fortune. Its association with intention or action is historical interpretation, not a measured mental or spiritual property.
Harmonics & patterns
Also: lowest harmonic only
A search rule that retains the smallest matching harmonic for a planetary combination, reducing listings of related higher harmonics.
Word origin, evidence & sources
Word origin · etymology
Descriptive numerical phrase.Lowest identifies the smallest harmonic number meeting the chosen rule. It describes an ordering of integer transforms, not an older named doctrine.
How we know · epistemology
Pattern-search conventionThe smallest qualifying harmonic is selected within the declared search range and pattern definition. This reduces related duplicates, but it is not an absolute property without those settings and does not make the retained pattern more evidentially meaningful.
Astronomy & calculated points
Also: apogee
The farthest point of a lunar orbit from Earth; an apogee direction is a geometric point, not another moon.
Word origin, evidence & sources
Word origin · etymology
Latin adjective and Greek-derived noun.Lunar means of the Moon; apogee derives from Greek apo-, away, and ge, Earth. Together they name the Moon's farthest orbital point.
How we know · epistemology
Orbital distance geometryLunar distance observations and orbital calculations identify farthest-distance points or events. A chart's apogee direction requires a stated model; it should not be confused with an additional object occupying that position.
Chinese & East Asian calendars
The first day of a new year in a lunar or lunisolar calendar. In the modern Chinese reference calendar, the first day of month one changes the official Gan-Zhi year.
Word origin, evidence & sources
Word origin · etymology
Descriptive English compound; lunar derives from Latin lunaris, from luna (Moon).New Year names the beginning of a calendar year. Lunar specifies its connection with a Moon-based calendar; Chinese calendar rules also use the solar year, so lunisolar is the more complete calendar description.

Also: lunar return chart · lunar returns
A chart for the instant the Moon reaches its natal ecliptic longitude again in the selected zodiac, conventionally read for the cycle to its next return.
Word origin, evidence & sources
Word origin · etymology
Descriptive English compound with a Latin-derived adjective.Lunar derives through Middle English from Latin lunaris, from luna (Moon). Return belongs to the English word family traced to Anglo-French returner, to turn back. The compound names a recurrence to a reference position; these word histories do not establish who first coined the astrological term.
How we know · epistemology
Calculated longitude recurrence with attributed symbolic interpretationThe crossing matches natal lunar longitude, not lunar phase. Monthly emotional or event themes are practitioner interpretations. Uncertain birth time changes the target; local houses also depend on the declared return place.
Time & location
Also: lunations
A lunar cycle from one new moon to the next. Its average length is about 29.53 days; a traditional calendar may use its own modeled lunation rather than a modern observed event.
Word origin, evidence & sources
Word origin · etymology
Middle English through French and Medieval Latin.Lunation is traced through Middle English lunacioun and French forms to Medieval Latin lunatio, built on Latin luna, moon.
How we know · epistemology
Astronomical cycle and calendar modelAn observed lunar cycle and a traditional computational month are related concepts, not automatically identical numerical objects. Phugpa month arithmetic uses the constants and correction rules of its specified model.
Chinese & East Asian calendars
A calendar combining lunar months with adjustments that keep the year aligned with the seasons.
Word origin, evidence & sources
Word origin · etymology
Latin-derived scientific compound.Luni- comes from luna, Moon, and solar from sol, Sun; the compound names calendar rules using both cycles.
How we know · epistemology
Rule-based astronomical calendarMonth starts and intercalation rules connect lunar cycles with the solar year. Calendars can differ through reference meridians and adopted rules even when using the same sky, so conversion requires naming the calendar rather than only its broad type.

Indian astrology
Also: mahādaśā
A major period in a dasha sequence, containing smaller subperiods.
Word origin, evidence & sources
Word origin · etymology
Sanskrit compound: mahādaśā.Mahā- is the compound form of mahant, meaning great; Rao glosses daśā as period. Mahādaśā therefore literally suggests a great period. This lexical explanation does not establish the term’s first historical use.
How we know · epistemology
Nested period arithmetic and attributed chart interpretationThe period schedule is a reproducible calculation under stated conventions; its life interpretation is a traditional astrological claim. A correct date calculation does not test that claim. Treat the reading as a contextual account, and record disagreements without changing the convention to fit an event. This tool uses the natal Moon under a selected sidereal reference and either 360 or 365.25-day years. Rao discusses competing year lengths. Compare dates only when all input and convention choices match.

Source-specific interpretive designationThe Wise Society teaching table names one main stem for each branch. That designation can be reproduced; how it contributes to strength or seasonal command needs a separate method.
Zodiac & chart foundations
A traditional label, especially for Mars and Saturn, describing an interpretive tendency rather than guaranteed harm.

Word origin · etymology
Latin borrowing.Latin maleficus combines male, badly, with a form of facere, to do. The traditional label describes a harmful influence.
How we know · epistemology
Historical interpretive categoryClassical texts use this category for demanding or adverse tendencies within context. It is not an observed harmful force, a moral description of a person, or a prediction of inevitable injury.
Human Design

The 5th lunar mansion in the modern Ashwini-first 27-division sequence. Its Sanskrit name also belongs to a historical named asterism; the atlas locates the Moon in an equal sidereal longitude sector.
Word origin, evidence & sources
Word origin · etymology
Sanskrit compound mṛga + śiras or śīrṣa.Mṛga denotes a wild animal, especially a deer or antelope; śiras and śīrṣa denote the head. The dictionary records Mṛgaśiras, Mṛgaśirā and Mṛgaśīrṣa as forms of the mansion name, explaining the range of English spellings.

Observed body and symbolic associationNeptune's distant orbit gives it slow apparent zodiacal motion shared by many birth cohorts. Interpretations involving imagination or uncertainty come from modern astrology; a placement alone cannot establish an individual's psychological state.
Chinese & East Asian calendars
Also: Kyūsei · Nine Star
A family of divinatory calendar practices relating nine numbered designations to qualities and directions. This explorer implements one annual cycle with two explicitly named year boundaries.
Word origin, evidence & sources
Word origin · etymology
English rendering with Japanese terminology.Kyūsei, 九星, names nine stars in Japanese divinatory terminology. Ki is a reading of 気, whose meanings include air, breath, atmosphere and disposition. The English title combines these terms; this word history does not establish a single origin date or lineage for every modern Nine Star practice.

A longitude frame measured from a chosen lunar node. In the usual draconic convention, the North Node becomes 0° Aries.
Word origin, evidence & sources
Word origin · etymology
Descriptive mathematical compound.Node names the orbital crossing and relative means referenced to it; frame names the coordinate convention used for the comparison.
How we know · epistemology
Coordinate convention with symbolic interpretationSubtracting the same node longitude preserves angular separations. Mean and true nodes give different offsets. Claims about underlying motivations belong to the interpretive method; the rotation does not measure a soul or past life.

Word origin · etymology
Latin through French.From oppositio, placing against or opposite. The geometry uses the same opposed-position idea for a half-circle separation.
How we know · epistemology
Angular criterionThe geometry is near half a circle in the chosen coordinate. Reading it as tension or complementarity is a traditional analogy, not a measured conflict between people or forces.
Aspects & angular relationships

Latin through French.Latin orbis means circle, disk, or sphere. Astrology extended the surrounding-circle idea to a permitted range around exact contact.
How we know · epistemology
Practitioner toleranceAn orb decides which near-matches count under a technique. Widening it changes the result set, so the tolerance must be declared before comparison; it is not a measured radius of influence.
Astronomy & calculated points
Also: True Lilith
The apogee of an instantaneous fitted lunar orbit; its changes include short-period effects and differ from the mean apogee.
Word origin, evidence & sources
Word origin · etymology
Latin and Greek mathematical vocabulary.Osculating comes from osculari, to kiss; a locally fitted orbit metaphorically kisses the actual trajectory. Apogee means far from Earth.
How we know · epistemology
Instantaneous fitted-orbit geometryAn ellipse fitted to the current lunar state supplies this apogee. Perturbations continually change that fit, so its direction is not necessarily the place of the Moon's next actual greatest distance from Earth.

Nested angular divisionA pada follows mechanically from a position within its nakshatra. Close to a quarter boundary, small changes in time or sidereal reference can alter the assignment; the resulting character descriptions are a separate tradition.
Indian astrology
A lunar fortnight: the waxing half is Shukla Paksha and the waning half is Krishna Paksha.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: pakṣa.Pakṣa means wing, side, or half, and hence a fortnight; the lunar cycle has a waxing side and a waning side.
How we know · epistemology
Lunar phase conventionThe waxing and waning halves follow the changing Sun–Moon angle. Their boundaries are astronomical phase events; any preference for one half for a particular activity is an additional cultural or astrological rule.
Chinese & East Asian calendars
Also: Zi Wei palace
A chart compartment representing a topic in systems such as Zi Wei Dou Shu; it is not automatically a Western house.
Word origin, evidence & sources
Word origin · etymology
English rendering of Chinese gōng, 宮.Palace names a residence or enclosure; the chart use translates the traditional palace metaphor for a compartment assigned a topic.
How we know · epistemology
System-specific topic assignmentA palace organizes a tradition's topics within its chart structure. Its meaning comes from that system's naming and placement rules; matching a palace number to a Western house number does not establish equivalent interpretations.

Indian astrology
Also: nitya yoga
One of 27 divisions of the sum of sidereal Sun and Moon longitudes; distinct from other meanings of yoga.
Word origin, evidence & sources
Word origin · etymology
Sanskrit calendrical compound.Yoga comes from yuj, to join or yoke. Here joining refers to the calendrical combination of the Sun's and Moon's longitudes.
How we know · epistemology
Traditional angular combinationAdding the selected sidereal Sun and Moon longitudes gives a reproducible sector index. That sum is a calendrical construction, not a measured interaction, and its interpretation differs from other Indian uses of the word yoga.
Astronomy & coordinates
A change in apparent direction caused by observing from different positions.
Word origin, evidence & sources
Word origin · etymology
Greek through French.Greek parallaxis means alteration, from a verb meaning to change. Astronomy applies the name to a viewpoint-dependent shift.
How we know · epistemology
Observable geometryA baseline change produces a geometrically testable directional shift. Its size depends on distance and observer separation; a single geocentric longitude does not capture the full local effect.
Aspects & angular relationships
Also: declination parallel
Two objects at nearly the same declination, using a stated tolerance.
Word origin, evidence & sources
Word origin · etymology
Geometric phrase.Parallel comes from Greek language for being beside one another; of declination specifies the coordinate being matched.
How we know · epistemology
Equatorial angular criterionThe comparison uses matching declinations within a stated tolerance. It is not a zodiac-longitude conjunction; any analogous interpretation is a school’s choice rather than a consequence of coordinate equality.
Location techniques
Also: parans
A locally timed relationship in which two bodies reach named horizon or meridian events together or within a declared tolerance; it is not a zodiacal longitude aspect or a map-line crossing.
Word origin, evidence & sources
Word origin · etymology
Modern practitioner shortening of Greek-derived paranatellonta.Skyscript glosses paranatellonta as “rising together.” This supports the word history and older co-rising idea. The claim that a modern paran may pair rise, upper transit, set, or lower transit is a practitioner convention, not an etymological consequence.
How we know · epistemology
Simultaneous angular-event criterionA topocentric geometric event search can reproduce declared horizon and meridian timestamps when location, time scale, ephemeris, body point, event kinds, and tolerance are retained. Traditional symbolic meaning is separately attributed; correct event arithmetic does not validate a personal claim. Geometric 0° horizon events with no refraction are not observations of visibility through weather, terrain, twilight, or atmospheric refraction.
Gene Keys
A Gene Keys sequence exploring contribution and prosperity; it does not predict income or financial success.
Word origin, evidence & sources
Word origin · etymology
Modern authored metaphorical title.Pearl names a valued gem formed within a shell. The sequence title uses this precious-product metaphor in the Gene Keys curriculum.
How we know · epistemology
Contribution contemplation frameworkThis sequence frames prosperity through selected symbolic themes. Its assignments are not economic measurements; neither a key nor a line establishes likely income, business success or the suitability of a financial decision.
Horary & traditional technique
Also: peregrine planet · peregrine planets
A planet with none of the five essential dignities at its position: domicile, exaltation, triplicity, term or face, under the selected tables and day/night rules.
Word origin, evidence & sources
Word origin · etymology
Latin through French.Peregrinus means foreign or from abroad. A planet without essential dignity is described through the metaphor of a stranger away from home.
How we know · epistemology
Absence of assigned essential dignityThis condition requires checking all five essential dignities under the selected table, including the applicable day/night rule for triplicity. Absence of domicile or exaltation alone cannot prove peregrine; the historical category is not evidence of dishonesty, social exclusion, or a person’s worth.
Horary & traditional technique
Also: perfecting an aspect
Exact completion of an aspect; in horary judgement, also the inferred fulfilment of the matter through specified testimonies. Distinguish the two uses.
Word origin, evidence & sources
Word origin · etymology
Latin through French.From perfectio, completion. Horary uses the completion sense for a contact or arrangement bringing the judgment to fulfillment.
How we know · epistemology
Geometric event and horary judgmentAn exact aspect is a calculable event, whereas fulfillment of a question is an interpretive conclusion. Applying motion must be followed through intervening changes; present proximity alone establishes neither future exactness nor the real-world outcome.

Eponym.Named after Placidus de Titis, the seventeenth-century astrologer associated with this house method. The label is an eponym.
How we know · epistemology
Spherical division methodThe method derives cusps through time-based divisions of diurnal motion. Some high-latitude configurations lack solutions; substituting another method without disclosure changes the chart’s stated construction.
Physical bodies
A physical Solar System body in the astronomical classification; astrological lists also include lights and calculated points.
Word origin, evidence & sources
Word origin · etymology
Greek through Latin and French.Greek planēs means wanderer. The name records the bodies' changing positions against the background stars.
How we know · epistemology
Astronomical and traditional classificationsAstronomy classifies physical bodies using stated criteria, while astrology often uses planet as a broader working category. A list should identify which meaning it uses; a calculated node does not become a physical planet through inclusion in that list.
Horary & traditional technique
Also: in fall
A traditional debility assigned in the sign opposite a planet’s exaltation sign; it is distinct from detriment, which is opposite domicile.
Word origin, evidence & sources
Word origin · etymology
Ordinary English word used as a status metaphor.Fall supplies the downward counterpart to exaltation's elevation. Planetary specifies whose traditional dignity status is being described.
How we know · epistemology
Opposition within an exaltation schemeThe condition follows a zodiacal table rather than a body’s downward motion or the autumn season. Its name does not establish moral failure or make an adverse judgment inevitable.
Horary & traditional technique
Also: planetary moieties
Half of a planet’s adopted orb. In a pairwise moiety calculation, the two halves are added to set the tolerated deviation from an exact aspect.
Word origin, evidence & sources
Word origin · etymology
French through Middle English, with Latin roots.Moiety means a half or portion, from Latin medietas. The aspect rule uses a half-share of a planet's orb.
How we know · epistemology
Traditional angular tolerance conventionThe arithmetic is reproducible once the orb table is declared. Lilly records alternative values; the resulting tolerance is a traditional selection rule rather than a measured radius of influence.

Indian astrology
Also: praśna
Question astrology: a chart for a question or consultation, requiring an event time rather than simply a birth time.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: praśna.Praśna means question or inquiry. The practice is named for the question being put, rather than for a birth.
How we know · epistemology
Question-based divinationThe chosen question or consultation moment supplies the chart's context. Reproducible calculation requires recording that moment and location; a birth chart answers a different setup, and symbolic testimony cannot establish hidden facts about another person.
Calculation concepts
The slow change in Earth’s axis orientation that shifts equinox-based coordinate references relative to distant stars.
Word origin, evidence & sources
Word origin · etymology
Latin through Medieval Latin.From praecessio, going before. The name originally referred to the equinoxes occurring progressively earlier against the stars.
How we know · epistemology
Observed and modeled motionChanges in Earth’s orientation are modeled from astronomical evidence. Their coordinate effects explain changing equinox references; they do not by themselves select one astrological zodiac as the correct interpretive system.

Historical geometric timing methodThe method combines spherical geometry with a chosen conversion from arc to years. Matching the geometry tests the construction; the timing key and event interpretation remain distinct assumptions.
Human Design
A Human Design type with some definition, an undefined Sacral and no motor-to-Throat connection.
Word origin, evidence & sources
Word origin · etymology
English agent noun with Latin roots.Projector derives from project, to throw or put forward. Human Design reuses the word as a type name; ordinary projection is only its lexical background.
How we know · epistemology
Connection-based graph categoryThe chart has some definition but lacks both Sacral definition and a motor-to-Throat path. The assigned guidance about recognition and invitations is a practice within Human Design, not proof of limited ability to act independently.

The 8th lunar mansion in the modern Ashwini-first 27-division sequence. Its Sanskrit name also belongs to a historical named asterism; the atlas locates the Moon in an equal sidereal longitude sector.
Word origin, evidence & sources
Word origin · etymology
Sanskrit puṣya, a word with nourishment and flowering senses.The dictionary records nourishment and a blossom or foremost-part sense under puṣya, and identifies the mansion also called Tiṣya. The short English form Pushya represents ṣ with sh; it does not mean that the distinct name Tiṣya has the same derivation.
How we know · epistemology
Lexical attestation, ritual tradition and a stated coordinate conventionThe dictionary attests Puṣya and its Tiṣya alias; the hymn supplies a deity association. The udder is a cited teaching emblem. None of these facts by itself supplies the additional rules needed for an auspicious-time judgement.

Modern coined name plus Sanskrit loanword.Mandala comes from Sanskrit maṇḍala, circle or disk. Rave is the school's distinctive name; its deeper naming rationale is not established here.
How we know · epistemology
Assigned zodiac–hexagram correspondenceThe system places sixty-four gates in a prescribed order around the zodiac. Coordinates determine the selected sector, but the association between that sector and an I Ching theme is inherited from the teaching rather than astronomical observation.
Horary & traditional technique
A traditional relationship in which a planet occupies another planet's dignity; state who receives whom and whether the method additionally requires an aspect.
Word origin, evidence & sources
Word origin · etymology
Latin through French.From receptio, a receiving. Astrology applies the receiving or hosting metaphor to a planet in another planet's dignity.
How we know · epistemology
Directional traditional relationshipThe dignity holder receives the occupying planet under the selected rule. Mutual reception requires both directions; whether an aspect is additionally required, and how it contributes to perfection of a matter, are separate method questions. A positional hosting label alone cannot establish cooperation, contact, or completion.
Harmonics & patterns
Also: reduced order · primitive harmonic relation · reduced rational harmonic
The denominator left after the nearest rational angular fraction k/h has been reduced to lowest terms. It identifies the smallest integer harmonic represented by that exact fraction and is distinct from a tool's lowest-qualifying-harmonic search option.
Word origin, evidence & sources
Word origin · etymology
Modern descriptive compound using mathematical 'reduce' and 'order'.Reduced means expressed in lowest terms; order names the denominator used to index the smallest repeating angular division. It is an Atlas display term, not a historical school label attributed to Cochrane.
How we know · epistemology
Number-theoretic reduction of a stated angular fractionFor a pair 72° apart, the nearest exact fraction is 1/5 and the reduced order is 5. That pair is also conjunct in H10, but H10 does not convert its primitive relation into a tenth-harmonic teaching. Nearness is separate: the inspector should display residual and declared orb, then say whether the selected factor qualifies.

Also: retrograde motion
Apparent backward movement in a selected, usually geocentric, coordinate frame; it does not mean that a planet physically reverses its orbit.
Word origin, evidence & sources
Word origin · etymology
Latin through Middle English.Retrogradus means going backward, from retro- and gradi, to step or go. The chart usage describes apparent backward longitude motion.
How we know · epistemology
Apparent motion in a reference frameSuccessive positions establish whether longitude is increasing or decreasing in the declared frame. In a geocentric chart this can be an apparent reversal produced by relative motion and viewpoint. Traditional horary associations such as delay, return, or reversal are interpretive and require the rest of the selected method; they are not measured consequences of the motion.

Descriptive English technique name.Return names a body's coming back to a specified reference position; chart names the diagram cast for that event.
How we know · epistemology
Calculated crossing with symbolic useThe returning body's longitude match defines the chart. The selected cycle and location complete its setup; interpreting that chart as a period's themes is a further practitioner convention.

Word origin · etymology
Sanskrit rohiṇī, a feminine form associated with rohita, red.For the mansion, the dictionary explains the name through the reddish appearance of Aldebaran. It also records rohiṇī as a feminine of rohin, associated with growing; that separate lexical connection should not replace the stated colour explanation of the stellar name.

Chinese sānhuì 三會: sān means ‘three’; huì means ‘meet, assemble, converge.’‘Seasonal meetings’ specifies the directional and seasonal use of the label in this entry. 三會/三会 are traditional and simplified written forms; romanization renders the modern Mandarin reading and does not establish one historical pronunciation.

Traditional seasonal-directional correspondences and calendar-derived membership calculationThe native tool reports a complete listed group only when its three different branches appear in the four calculated pillars. Its four phase/season labels follow a traditional correlative table; they are not measured energy, proof that a group has ‘transformed,’ or a prediction. The origin and exact status of ‘three meetings’ as a single standardized BaZi term varies across later teaching lineages, so this entry does not assign it a single author or date.

Timing & comparison
Also: secondary progression
A Western astrological timing method that symbolically maps one day after birth to one year of life; it is not a chart of the current sky.
Word origin, evidence & sources
Word origin · etymology
The ordinary English words secondary and progression: secondary denotes a second order or stage, while progression denotes advancing or a connected sequence.Merriam-Webster establishes those general English senses, not the historical naming of the astrological technique. Available method documentation distinguishes secondary progressions from primary directions and solar arcs, but it does not establish why this method acquired the label “secondary.” This entry therefore makes no founding-author, first-use, or derivation claim for the technical name.

An Indian annual-chart tradition using solar returns together with distinctive aspect and timing rules.
Word origin, evidence & sources
Word origin · etymology
Sanskrit borrowing through Persian.Tājika derives from Persian tāzīg, Arab, ultimately associated with the Arabic tribal name Ṭayyiʾ. Indian usage designated Perso-Arabic people and astrology.
How we know · epistemology
Historical annual-chart methodA solar return provides the astronomical anchor, while Tajika supplies its own aspects and judgment rules. A natal interpretation or generic transit reading cannot stand in for that method merely because the same planets appear.

Word origin, evidence & sources
Word origin · etymology
Chinese 貪狼; Chan renders the name “Greedy Wolf.”The translation is documented here, but its historical adoption into Zi Wei remains unverified. The name is not a moral verdict.
How we know · epistemology
Contemporary explanation of traditional chart symbolism.An appetite metaphor does not establish addictive behavior, sexual conduct or ambition in any individual.

Chinese shíshén 十神, literally ‘ten spirits/deities’.The literal name is documented as a traditional label. This draft makes no claim about when the name was coined or that it describes literal supernatural beings.
How we know · epistemology
Traditional/practitioner interpretive classificationThe label is a rule-based chart relation, not a measured personality trait, forecast, or scientific finding. A label alone does not establish strength, favourability, or an event outcome.
Time & location
Also: TT
A uniform time scale used in astronomical models; it differs from rotation-based UT1.
Word origin, evidence & sources
Word origin · etymology
Standardized English name.Terrestrial comes from Latin terra, earth. TT abbreviates Terrestrial Time, the Earth-associated theoretical time scale.
How we know · epistemology
Astronomical time scaleTT supplies the time argument for uniform astronomical models. It is not the time shown on an ordinary birth record, and the correct conversion matters when comparing ephemerides.
Chinese & East Asian calendars
Also: Three combinations · Sānhé 三合 · Sanhe · Earthly Branch three harmonies · Dìzhī sānhé 地支三合 · 三合
In BaZi, four conventional three-branch groups: Shen–Zi–Chen, Hai–Mao–Wei, Yin–Wu–Xu and Si–You–Chou; the tool reports full membership when all three distinct member branches occur.
Word origin, evidence & sources
Word origin · etymology
Chinese sānhé 三合: sān means ‘three’; hé means ‘join, combine, accord.’‘Three harmonies’ is a common English rendering; ‘three combinations’ stays closer to the literal relation label. The compound names a conventional group and does not assert that all chart occurrences are harmonious in an everyday or psychological sense.
How we know · epistemology
Traditional branch-group convention and calendar-derived membership calculationThe chart calculation can establish only whether each cited three-branch membership set is complete among the four visible Earthly Branches. Traditional explanations associate the sets with phases and a birth–prosperity–storage sequence, but those correspondences are inherited interpretive material, not a measured property of a person.

Sanskrit calendrical word.Tithi names a lunar day. The inherited technical meaning is secure; a deeper root or literal syllable breakdown is not established here.
How we know · epistemology
Solar–lunar phase geometryThe Moon–Sun longitude difference determines the tithi independently of civil midnight. Tithis have unequal clock durations and may cross a sunrise boundary; calendar use must distinguish the instantaneous value from the day's assigned value.
Human Design
Also: Human Design tone
One of six subdivisions within a Human Design color; it is not a measured sound frequency.
Word origin, evidence & sources
Word origin · etymology
Greek through Latin; modern metaphorical label.Tone ultimately comes from tonos, tension or pitch. The system borrows this musical/sensory word for a level below Color.
How we know · epistemology
Fine angular subdivisionSix tones subdivide each color under a fixed mapping. Their sensory and cognitive associations are part of the teaching; the angular calculation does not measure hearing, neural processing or a physical vibration.
Astronomy & coordinates
Measured from a specified place on Earth, including the observer’s location-dependent shift in direction.
Word origin, evidence & sources
Word origin · etymology
Greek combining forms.Topo- comes from topos, place. The name means centered on a particular observing place, rather than Earth's center.
How we know · epistemology
Observer conventionAdding a surface observer accounts for location-dependent parallax. Accuracy still depends on coordinates, elevation and correction choices; it does not imply that a related astrological interpretation is locally validated.
Timing & comparison
Also: transits
A moving planet’s position at another date, often compared with a natal position.
Word origin, evidence & sources
Word origin · etymology
Latin-derived noun.Latin transitus is a passage or crossing, from transire, to go across. Astrology applies it to moving bodies passing chart positions.
How we know · epistemology
Astronomical comparisonA second instant supplies moving positions that can be compared with a fixed chart. The contact can be calculated precisely; its proposed connection to a personal event needs separate assessment.
System gateways
Transits compare a later sky with an earlier chart.

Aspects & angular relationships
An aspect near 120° separation in zodiac longitude.
Word origin, evidence & sources
Word origin · etymology
Latin through French.Latin trinus means threefold, from trini, three each; a trine spans one third of a circle.
How we know · epistemology
Angular criterionThe geometric relationship divides the circle into thirds. Its usual favorable symbolism is inherited interpretation; identifying a trine does not demonstrate ease, talent or an eventual success.

Zodiac & chart foundations
Twelve equal 30° signs beginning at the March equinox, tied to the seasonal reference rather than constellation boundaries.
Word origin, evidence & sources
Word origin · etymology
Classical astronomical terminology.Tropical is related to the tropics and turning of the Sun; zodiac descends from Greek terminology for the band of figured signs.
How we know · epistemology
Seasonal coordinate conventionThe equinox defines the origin of twelve equal sectors. That construction is reproducible; linking a sector to character or events is a further interpretive claim, not a result of the coordinate definition.
Astronomy & calculated points
Also: True North Node
A node calculated from the Moon’s instantaneous orbital geometry; it can briefly move direct despite the mean node’s retrograde motion.
Word origin, evidence & sources
Word origin · etymology
Historical astronomical model label.True is the conventional counterpart to mean, indicating an instant-dependent rather than averaged node. The adjective is part of the model's name.
How we know · epistemology
Instantaneous orbital modelThe calculation uses the Moon's instantaneous orbital geometry, retaining variations omitted by a mean model. True names that modeling choice; it does not establish that this node convention produces truer astrological interpretations.
Tibetan calendars
A Tibetan calendar tradition with calculations differing from Phugpa; it is not simply another timezone setting.
Word origin, evidence & sources

Also: undefined centers
A BodyGraph center without a complete activated channel; it may still contain one or more activated gates.
Word origin, evidence & sources
Word origin · etymology
Descriptive modern chart phrase.Un- negates defined. In this specialized vocabulary a center can be undefined while still containing an activated gate.
How we know · epistemology
Graph-derived categoryThe absence of a completed channel gives this label even when some gates are activated. It identifies a structural condition; it does not establish weakness, suggestibility or a deficiency in the corresponding area of life.
Horary & traditional technique
A traditional label for a planet within a stated vicinity of the Sun. Some methods separately identify combustion and cazimi within that wider vicinity; the Atlas ledger displays mutually exclusive categories under its named rule.
Word origin, evidence & sources
Word origin · etymology
English descriptive phrase; beam is an Old English and Germanic word whose light-ray sense developed in Old English.The phrase uses beam in its light-ray sense. The retrieved sources trace beam to Old English beam, ‘tree, beam’, with a cognate Old High German boum, and report that the ray-of-light sense developed in Old English. The deeper origin is uncertain in the cited etymological account. This word history does not set an astrological solar-proximity boundary.
How we know · epistemology
Solar-proximity classification with source-dependent boundariesThis label can be calculated only after the source's solar-proximity range and priority between nearby categories are stated. It is a chart rule based on a coordinate separation. It should not be read as an observational visibility report: visibility also depends on sky brightness, altitude, atmosphere, magnitude, and observer conditions.

Word origin · etymology
International abbreviation.UTC is the agreed abbreviation of Coordinated Universal Time. It does not follow the order of the English words.
How we know · epistemology
Civil time standardUTC is an agreed time standard realized through timekeeping institutions. A UTC timestamp identifies an instant, but converting an old local birth record still requires the relevant historical clock rules.
Time & location
Also: utc_offset_seconds
The amount added to UTC to obtain local civil time at a particular instant.

Also: vāra
The weekday factor in a panchanga; traditional daily reckoning commonly begins at local sunrise.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: vāra.Vāra means a turn, recurring occasion, or day; the weekday meaning uses this recurrence vocabulary. The long vowel distinguishes it from other vara words.
How we know · epistemology
Local calendrical day ruleA weekday is familiar civil information, but a traditional sunrise-based vara can differ from the midnight-based date before dawn. A trustworthy result states the location and day boundary used rather than silently mixing both conventions.
Indian astrology
Also: divisional chart · vargas
An Indian chart division and remapping; different vargas require distinct rules, not simply generic longitude multiplication.
Word origin, evidence & sources
Word origin · etymology
Sanskrit transliteration: varga.Varga means a class, group, division, or section. Its chart use applies this division vocabulary to zodiacal subdivisions.
How we know · epistemology
Family of divisional conventionsEach varga requires its own assignment rule and stated treatment of boundaries. Agreement on the division number alone is insufficient for reproduction, and the life topic assigned to a division comes from its interpretive tradition.
Jyotish & derived charts
Also: vargotamma
A planet or Lagna occupies the same zodiac sign in the D1 rashi chart and D9 navamsha chart.
Word origin, evidence & sources
Word origin · etymology
Sanskrit compound: vargottama.Varga means class or division and uttama highest or best; the compound names the specially valued matching divisional placement.
How we know · epistemology
Traditional Jyotish classificationThe same-sign match is reproducible from the chosen chart settings. Practitioners give it interpretive weight, but matching signs alone do not establish strength, favourable outcomes or freedom from other difficult conditions.

A 120-year planetary period scheme commonly initialized from the natal Moon’s nakshatra and its remaining portion.
Word origin, evidence & sources
Word origin · etymology
Sanskrit numerical system name.Viṃśottarī designates the 120-year scheme; daśā means period or condition. The numerical name concerns the full nominal cycle.
How we know · epistemology
Nakshatra-based timing conventionThe selected lunar mansion and fraction remaining initialize a prescribed 120-year sequence. Ayanamsha, lunar precision and year length can shift dates; the sequence's arithmetic does not establish that its periods cause particular events.
Zodiac signs

Indian astrology
Also: Viśākhā · Visakha · Vishakha nakshatra
The sixteenth mansion, with a name associated with branching. Its traditional deity pairing is Indra and Agni.
Word origin, evidence & sources
Word origin · etymology
Sanskrit Viśākhā, feminine of viśākha.Monier-Williams analyzes viśākha with vi- and śākha and records branched or forked among its senses. The feminine names the mansion. This supports a branch image, but not a claim that the name predicts divided loyalties or two marriages.
How we know · epistemology
Lexical record and traditional paired deitiesThe dictionary documents the name, arch image and dual deity association. Applying branching to a person’s choices is a metaphor; it does not justify claims about relationship outcomes or inevitable conflict.
