The Jia Zi Pair (甲子): Jiazi Explained

Jia Zi (甲子) is the 1st of the sixty Jiazi pairs, the stem-branch combinations that structure the entire Chinese calendar, BaZi charts and Qi Men Dun Jia timing alike. In the current cycle its years are 1984 and 1985, followed by its partner pair Yi Chou (乙丑) completing the same nayin group.

Jia Zi Quick Facts

What the Jia Zi Pair Means: A Nourishing Pair

Classical analysis of a stem-branch pair starts with their elements, and here the branch feeds the stem: Water generates Wood. The ground nourishes the core, which classically reads as a supported, well-fed pairing where circumstances feed the person’s own energy rather than fight it.

This relation is why two pairs can both be called auspicious while feeling completely different in a life. The nourishing pairs suggest support arriving from the environment; the commanding pairs suggest the person taking charge of the environment; the disciplining pairs suggest life itself as the teacher. None of the five relations is good or bad. Each is a style of exchange between a person’s core and their ground.
