Open the branch explorer →A fixed set of six opposing pairs
The six clashes (liùchōng 六沖) are Zi–Wu (子–午), Chou–Wei (丑–未), Yin–Shen (寅–申), Mao–You (卯–酉), Chen–Xu (辰–戌) and Si–Hai (巳–亥). Bu Shi Quanshu lists these six pairs directly; Joey Yap’s published BaZi material also presents the branch-clash table.
The pair set is a conventional relation among Earthly Branches. It does not follow from a generic claim that two Five Phases control each other, and it is not interchangeable with combinations, harms, punishments or other named configurations.

What the native tool calculates
After the four pillars have been calculated, the detector compares their four visible Earthly Branches against only these six pairs. It checks year–month, year–day, year–hour, month–day, month–hour and day–hour, then returns each match and both positions.
The output marks adjacent matches separately from distant ones, preserving the chart’s displayed pillar positions. It does not rank those positions, examine hidden stems, allocate phase weights or determine which branch wins.
Traditional readings require stated context
A clash label is used in traditional interpretive work, but the label does not settle its effect. A commentary in Di Tian Sui Chan Wei discusses Zi–Wu, Mao–You, Yin–Shen and Si–Hai with conditions involving seasonal command and other branches and stems, illustrating that context is part of that style of judgment.
This explorer does not choose such conditions or turn them into a rule. It makes the narrow calculation transparent; any subsequent traditional interpretation should identify its school, inputs and source rather than treating ‘clash’ as a universal negative verdict.

Worked pair: Mao–You 卯–酉
Suppose the visible branches are year Chen, month Mao, day Wei and hour You. Among the six positional comparisons, the detector reports Mao–You at month–hour. It identifies this as a distant displayed-position match because the day pillar lies between the matching branches.
The calculation establishes only that a listed six-clash pair occurs at month–hour. It does not identify a relationship problem, a relocation, a health result, a forecast or a stronger branch. Those are separate interpretive claims and need their own method and evidence.
In the combined explorer, Chen–You at year–hour also matches the six-combination table. Both observations remain visible; this detector does not make one cancel the other.
Keep the relation and its limits visible
The native calculation covers the six two-branch clash pairs only. The same explorer also checks the separate six-combination table. Triple relations, harms, punishments, phase weights and timing need additional methods.
Six-clash membership is a traditional label on a calendar-derived chart. It is not a measured indicator of conflict, illness, compatibility or future events, and no good-or-bad conclusion follows automatically from the presence of a pair.
A reflective prompt, not a reading
Original Astral Atlas reflection: If you choose to reflect on the label, ask: “What do I notice when I place these two calculated branch positions beside a tradition that calls them a clash?” Treat the question as a prompt for your own observations, not a claim about what must happen.
Record the computed branches, positions and calendar convention alongside any reflection. Keeping those inputs visible separates an auditable calculation from later meaning-making.
Word origin · etymology
Chinese liùchōng 六沖: liù means ‘six’; chōng means ‘rush against’ or ‘clash.’ Pinyin is editorial romanization, not evidence of a single historical pronunciation or a universal psychological meaning.
‘Six clashes’ translates the relation label. The English wording does not turn a detected pair into a diagnosis, a forecast or an automatic bad outcome.

How we know · epistemology
Traditional branch-pair convention and interpretive input
A clash is a sourced relationship label for a listed opposite pair. The detector can report its presence and pillar positions; it does not measure conflict, prove a life outcome or establish that either branch overcomes the other.
