BaZi calculator FAQ
Do I need my exact birth time for BaZi?
The hour sets the Hour Pillar, so the more precise it is, the better. If you are unsure, use an approximate time. The year, month and day pillars do not change.
Can I use the BaZi calculator without signing up?
Yes. With no login you see a preview of your pillars, Day Master and element balance, and nothing is stored. The AI reading is generated and saved only after you sign up.
How accurate is the chart?
The pillars come from a fixed calendar conversion using solar terms and true solar time, so you can check them against a traditional almanac. The interpretation is for entertainment and self-reflection.
Is the full reading free?
New accounts get free credits for a full reading. After that you pay per reading with credits or buy a pass, and nothing renews automatically.
