Direct answer
What is BaZi Calculator?
The Eastern Type BaZi calculator uses your birth date, place, and optional time to calculate a Four Pillars chart, Day Master, Five Element presence, and a plain-English starting point.
How it works
Enter birth date, place, and time when known. The deterministic engine calculates the chart; interpretation explains the displayed signals in plain English.
What you get
You can review Four Pillars, Day Master, Five Element presence, and an Eastern Type starting point. The Deep Personal Profile is coming soon, not available now.
Limitations
This is a cultural self-reflection framework, not a scientific test or a fixed prediction. It does not provide medical, legal, financial, or other professional advice. If birth time is unknown, the Hour Pillar is not invented; the result is explicitly partial.
Frequently asked questions
What inputs are needed?
Enter your birth date and place; add birth time when known for a fuller chart.
What happens without a birth time?
The calculator returns a partial result and leaves the Hour Pillar unresolved.
Does AI calculate my chart?
No. The chart calculation is deterministic; AI does not change the chart values.
