The logic behind 黄历 (huánglì) — lunar days, zodiac clashes, and the famous 宜/忌 list.
For weddings, launches and moves, many Chinese families still consult the Chinese almanac (黄历 huánglì) — a 2,000-year-old calendar that marks each day as favorable or unfavorable for specific activities. Here's how it works.
Chinese dates follow the moon, so the same solar date falls on different lunar days each year. Festivals like the Lunar New Year and Mid-Autumn move accordingly. Every lunar day has a heavenly stem (天干) and earthly branch (地支) — these 60 combinations cycle through the calendar and carry different energies.
Each year has an animal (2027: Sheep 羊). Days whose earthly branch clashes with your birth year's animal are avoided; days that harmonize are favored. For example, a Dog-year bride would avoid days that clash with the Dog, and prefer days that combine well with it.
The almanac's daily list of what is favorable (宜) and unfavorable (忌) is the practical part most people use:
Note: the exact Yi/Ji list changes daily — always check the day itself.
Choosing an auspicious day isn't superstition to many — it's a way of starting something important with confidence and family support. Even in modern cities, most Chinese weddings are still scheduled using the almanac.
A daily almanac contains many columns. You do not need all of them to make a practical decision; these are the ones that matter most:
| Column | What it means | How to use it |
|---|---|---|
| 宜 yí | Activities traditionally considered suitable | Match the activity to your event |
| 忌 jì | Activities traditionally avoided | If the event appears under 忌, many families choose another date |
| 冲 chōng | Zodiac sign said to clash that day | Compare it with the birth years of the people involved |
| 煞 shà | Direction traditionally avoided | Usually a secondary factor, not the main wedding-date decision |
| 吉神 / 凶神 | Auspicious and inauspicious deities or directions | Read together with 宜/忌 rather than as a standalone verdict |
| Event | Almanac focus | Practical check |
|---|---|---|
| Wedding 结婚 / 嫁娶 | 嫁娶, 纳采, couple zodiac clash | Venue, family travel and season come first; use the almanac to shortlist |
| Moving 入宅 / 移徙 | 入宅, 移徙, household zodiac clash | Lease handover, movers and utilities may matter more than a perfect day |
| Business opening 开业 | 开市, 交易, owner zodiac clash | Staffing, stock and marketing launch date must also work |
| Contract 签约 | 立券, 交易 | Legal and commercial readiness come before the almanac |

宜 (yí) lists activities traditionally considered suitable for the day. 忌 (jì) lists activities traditionally avoided. The list changes from day to day and should be read in the context of the specific event.
It means the traditional almanac marks that activity as unsuitable. Many families will choose another date, but couples also weigh venue availability, work schedules, travel and other practical constraints.
No. The almanac gives a general daily reading; birth years, zodiac clashes, regional custom and family practice can change which dates a particular couple prefers.
