Your birthday is only used inside your browser and never uploaded. If you ask the kitten for a reading, only the finished chart is sent.

Curious how two charts fit together? Try Compatibility. Bazi is a traditional Chinese practice — read it for fun and reflection, not as advice on health, money, law or relationships.

How it works

Charts use Beijing time (UTC+8). If you were born elsewhere, convert your birth time to Beijing time first. China’s 1986–1991 daylight saving hour is removed automatically.
With a place of birth, the clock time is converted to true solar time (longitude plus the equation of time) before the day and hour pillars are set. After 23:00 counts as the next day.
The year changes at the Start of Spring (around February 4) and each month at its solar term, calculated from the Sun’s position (accurate to about 15 minutes).
Luck cycles run forward for men born in a Yang year and women born in a Yin year, backward otherwise; every 3 days to the nearest solar term counts as one year before the first cycle.
If you don’t know the hour, only the year, month and day pillars are drawn.
