Calendar Round →
The combination of the 260-day and 365-day counts, repeating after 18,980 days, approximately 52 years.
Word origin, evidence & sources
Round refers to the recurring combined cycle of the Haab and sacred count; it is an English explanatory name for their interlocking recurrence.
The two counts realign after their least common multiple of 18,980 days. A Calendar Round label repeats, so it cannot uniquely identify a historical date without additional chronological information.
Chol Q’ij →
Also: Chol Q'ij
The K’iche’ name for the living sacred day count, whose cultural practice should not be reduced to a generic birthday label.
Word origin, evidence & sources
Chol Q’ij is the K’iche’ name for the sacred day count, alongside the Yucatec name Tzolk’in. These are distinct language forms, not English acronyms.
The sacred count is sustained through K'iche' knowledge and practice, beyond its arithmetic pattern. A software conversion can identify a date under stated conventions; it cannot confer the authority or lived knowledge of a daykeeper.
GMT correlation →
Also: GMT 584283
The Goodman–Martínez–Thompson alignment of Maya and Julian day counts; this engine uses the constant 584283.
Word origin, evidence & sources
GMT stands for Goodman–Martínez–Thompson: Joseph Goodman, Juan Martínez-Hernández, and J. Eric S. Thompson. Here it does not mean Greenwich Mean Time.
A 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.
Haab →
Also: Haab’
A 365-day Maya calendar with eighteen twenty-day months plus a five-day period.
Word origin, evidence & sources
Haab, also written Haab’, names the solar-year calendar. Its language form is retained rather than replaced by the English calendar label.
The 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.
Long Count →
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
Long distinguishes a continuing count of elapsed days from shorter repeating calendar cycles; count names its chronological tally.
The 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.
Tzolk’in →
Also: Tzolkin · Tzolk'in
A 260-day Maya count combining thirteen numbers with twenty day names; names and living practices vary by language and community.
Word origin, evidence & sources
Tzolk’in is the Yucatec name used for the 260-day calendar. The apostrophe marks a glottalized consonant; no first coiner is established here.
The thirteen-number and twenty-name cycles make the day sequence reproducible once an anchor is fixed. A converted date alone does not reproduce the community-specific language, ritual authority or interpretive practice associated with the count.
