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 Plum Blossom numerology

Plum Blossom (梅花易數) is a way of consulting the I Ching without coins or stalks, traditionally credited to the Song dynasty philosopher Shao Yong. The hexagram is built from numbers — the date and hour when a question arises, or numbers that come to mind — and the answer is read from the relationship between two trigrams, the body and the use.

How it is calculated

With the time method, the year branch, lunar month and lunar day give the upper trigram; adding the double hour gives the lower trigram and the moving line. With the number method, your first number gives the upper trigram, the second the lower, and their sum the moving line. Fate Hall shows the primary, nuclear and changed hexagrams and compares the elements of the body and use.
