Every day in the Chinese calendar carries a stem and a branch, and the almanac is the tradition’s commentary on those two characters: their elements, their hidden influences, their clashes and combinations with the months and seasons around them. The result is a page of practical guidance that has been consulted — in China, and now in Chinese communities worldwide — for roughly three thousand years.
Where the advice comes from
Nothing in the almanac is invented day by day. Every entry is computed from the calendar itself: the day’s stem and branch, their five elements, their position in the month, and the classical tables of combinations and conflicts. That is why it is called a deterministic system — two almanacs computed from the same calendar agree. The day is favorable for travel because its branch allies with the month, not because anyone decided so.
How to read a day’s entry
- The lunar date and the day pillar — the day’s stem and branch, which set everything else.
- Favorable (宜) — what the day supports: starting business, travel, marriage, moving house, signing documents. The list is keyed to the day’s element relationships.
- Unfavorable (忌) — what the day resists: burying, breaking ground, major purchases, confrontations. Same computation, negative face.
- The day’s clashes — the animal that clashes with the day’s branch, traditionally advised to take care that day.
Why people still consult it
The almanac survives because it is actionable and non-binding: it gives the day’s character and lets you choose. Its practical value is the same as any planner’s — a second opinion on timing, checked before the big decision. Its cultural value is the connection to a calendar that has paced Chinese life for millennia.
