Method

BaZi pillars follow the solar calendar and solar terms (especially Li Chun for the year pillar). Birth city enables longitude-based true solar time correction near boundary moments.

How to use

Select gender, solar or lunar calendar (check leap month if lunar), then enter birth date. If the hour is unknown, check “Birth hour unknown” instead of filling time.
Optionally enter birth city. If you know the hour, fill birth time; otherwise leave “Birth hour unknown” checked.
Submit to open your BaZi result page.
Or switch to the reverse tab: pick four pillars (乾/坤 + stems/branches), search solar dates, select one, then chart.

FAQ

If I share my birth time or BaZi, can someone misuse it against me?: You do not need to overworry. Many people share the same four-pillar BaZi chart; whole cohorts are born in the same year, month, day, and two-hour period. BaZi summarizes a time coordinate; it is not a unique ID that pins down one person. Protect ID numbers, addresses, and passwords. We also do not sell birth data.
Where are chart records stored? Will you sell my birth data?: Records stay in this browser by default; signed-in users can sync to their account for other devices. We do not sell birth data or email lists. You can delete local records anytime; see the privacy policy for full details.
