FAQ

Is this BaZi calculator free?

This static page is free and built for chart education, quick lookup, and structured BaZi learning.

Why does birthplace matter?

BaZi work often depends on local time, time zone, and true solar time. Birthplace helps avoid a wrong hour pillar near boundary times.

Can I calculate without birth time?

You can still study the year, month, and day pillars, but the hour pillar and some timing details remain incomplete.
