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 feng shui and your Kua number

Eight Mansions feng shui (八宅) gives each person a Kua number based on the year of birth and sex at birth. The Kua number places you in the East Group or the West Group and assigns four favourable and four unfavourable directions, which traditional practitioners use to arrange a bed, a desk or a front door.

How it is calculated

The birth year is counted from the Beginning of Spring, as in BaZi. Your Kua number gives your personal trigram, and the eight directions are read from it: Sheng Qi (vitality), Tian Yi (health), Yan Nian (relationships) and Fu Wei (stability) are the favourable ones. You can enter your home’s facing direction to see how it matches your directions.

Using it

Feng shui is a traditional design philosophy. Simple, low-cost changes — which way your desk faces, where you place a lamp — are the usual starting point. It is not a substitute for building, safety or health advice.
