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 Nine Star Ki

Nine Star Ki (九星氣學) is a system of nine "stars" — One White Water through Nine Purple Fire — handed down in Japan and across East Asia. Each year, month and day is ruled by a star, and your principal star comes from your year of birth.

How it is calculated

The year begins at the Beginning of Spring, as in BaZi. The nine stars move through a magic square of nine palaces, one for each direction and the centre, and a new star takes the centre each year. Your principal star’s position on this year’s square is read as the theme of your year, and the directions around it as favourable or to be avoided.

Reading it well

Nine Star Ki is often used alongside feng shui for timing moves and travel. Treat the yearly position as a mood — a year in the centre is traditionally busy and visible, a year in the north quiet and inward — rather than a fixed outcome.
