I don’t know my birth time

Time basisClocks follow your time zone’s standard meridian, so the Sun at your birthplace can run minutes ahead of or behind the clock. Longitude correction fixes that offset; true solar time also adds the seasonal equation of time (±16 min). Rat-hour rule (23:00–00:59)Only matters if you were born between 23:00 and 23:59. Most modern practitioners use the early Rat-hour rule.

Why does birth time need correcting? ▾

Solar time, not clock time. In BaZi the hour pillar, and the day pillar near midnight, follow where the Sun actually was. Clock time is set for a whole time zone, so at your birthplace the Sun may cross the meridian earlier or later than clock noon. We use the longitude of your birthplace to correct for that, and can also add the equation of time (from −14 min in February to +16 min in November).

Daylight saving time is taken from your browser’s time zone database for the birth date, so summer-time births are converted to standard time automatically.

Whichever basis you pick, the “Pillars under each time basis” panel shows every combination side by side. If they differ, choose the one closest to the time on your birth certificate.

About the Chinese Almanac

For centuries, families in East Asia kept an almanac — the Huangli or Tong Shu — that printed a block of notes for every day of the year. This page calculates the main entries for any date between 1901 and 2049: the lunar mansion, the day officer, the god of the Yellow or Black Path, and the day’s clash and sha direction.

How it is calculated

The 28 lunar mansions follow an unbroken 28-day cycle tied to the days of the week. The twelve day officers count from the branch of the solar month, which starts at each solar term, so on the first day of a new month the officer repeats — just as in printed almanacs. The Yellow and Black Path gods follow the day branch from a starting point set by the month. Fate Hall combines these into a simple score and lists the best days of the next thirty.

The Chinese Almanac guide explains every entry with full tables, and notes how the calculation has been checked against an independent almanac for every day from 1950 to 2049.
