Today's AlmanacHow This Works
- ◆System: This tool uses the Twelve Day Officers (建除十二神). Each day in the traditional Chinese almanac gets one of twelve "officers," decided by how the day's branch relates to the solar month branch. Each officer has activities it favours (宜) and activities to hold off on (忌).
- ◆Calculation: Officer index = ((day branch minus month branch) + 12) % 12. The day branch comes from the same sexagenary day-pillar formula used by the Bazi calculator. The month branch comes from the solar term (节气) boundary, consistent with the daily almanac on this site.
- ◆Activity mapping: Each activity matches a set of officers that traditionally support it and a set that call for caution. Days that match neither are neutral. The mappings follow classical almanac tradition and are simplified for everyday use.
- ◆Zodiac clash: Every day has a "clash zodiac." That is the animal six steps away in the 12-branch cycle. If a day clashes with your own zodiac animal, tradition considers it less suitable for big plans. This shows as an extra flag on top of the officer rating.
- ◆What this is not: This is not a full date-selection service. Professional 择日 (date selection) looks at the year branch, month branch, your personal Bazi, and even the hour. This tool gives you one useful layer, the officer system, as a cultural starting point. Most practitioners treat this kind of guidance as a first filter, not a final answer.
This is a simplified almanac tool for cultural reference only. It is not professional date-selection advice. Every person's circumstances are different, and traditional almanac practice involves many more layers than the officer system alone.
