Questions people ask
Do I need to create an account to use BaZi Calculator?
No, it requires no sign-up and runs entirely in your browser.
Does BaZi Calculator cost anything?
It is free to use.
What if I don't know my exact birth hour?
The calculator can handle cases where the birth hour is unknown, or you can enter a traditional two-hour Shichen period instead.
Can I enter a lunar calendar birth date instead of a solar one?
Yes, the tool supports both solar and lunar calendar date input.
Why does the calculator ask about true solar time and location?
It uses true solar time, adjusted for longitude and historical timezone, because a correction near a two-hour boundary can change the Hour Pillar in the chart, and it lets you set an exact birthplace via a map.
