free Bazi calculator
Read your rhythm through the Four Pillars
Bazi maps the year, month, day and hour of birth into Four Pillars. This calculator first computes the chart deterministically, then asks an AI reader to interpret the recorded Day Master, Five Elements and luck cycles. The model does not invent chart data.

Common questions
What information do I need?
Enter your birth date, time, gender and calendar. A birthplace helps with location-specific chart calculations. Data is saved to your account only when you opt in to saved people.
Does the AI calculate the pillars?
No. A deterministic chart engine calculates the pillars; the AI explains those facts without changing stems, branches or scores.
