The Rooster branch is number 10 of the twelve: yin Metal, the animal Rooster, the 8th month (beginning at White Dew), the hour 17:00–19:00, direction West, season Autumn. Below are the structural facts — hidden stems, six-harmony, clash, harm, punishment, trine and meeting — plus which of the twelve stages each of the ten stems occupies on this branch. All of it is computed and checkable; none of it is a personality verdict.
This page is generated from the engine v0.14.0, not hand-written; structural facts reconcile against the methodology page.

Branch relations are fixed tables — combination, clash, harm, punishment, trine and meeting each have a defined membership. This site computes them from those tables and does not add the popular "once combined, everything improves" clause.
| Six harmony | 辰 Chen (Dragon) — combines into Metal |
|---|---|
| Six clash | 卯 Mao (Rabbit) |
| Six harm | 戌 Xu (Dog) |
| Punishment | Self-punishment (one of Chen, Wu, You, Hai) |
| Three harmony | Metal trine: 巳 Si (Snake) 酉 You (Rooster) 丑 Chou (Ox) |
| Meeting | West Metal meeting: 申 Shen (Monkey) 酉 You (Rooster) 戌 Xu (Dog) |
The twelve stages describe how strong a stem is on a given branch. Yang stems run forward, yin stems run backward, so each of the ten stems lands on exactly one stage per branch. The ten rows below are computed; the stage names link to their full definitions.

| 甲 Jia Yang Wood (yang Wood) | Conception | 11 of 12 |

Each branch appears in five of the sixty pillars (a yang branch only pairs with yang stems, a yin branch only with yin stems). Every pillar has its own page:
Every enumerable component of ba zi has its own page here. Each page is computed by the same engine and can be checked item by item — none of it is a personality table.
