Four Pillars chart

Cast a Four Pillars (BaZi) chart from a date, a time, and a birth place. You get the four pillars with their ten gods, hidden stems and stages, the element count, the relations, and the ten-year luck cycles. No account, no email, and nothing you type leaves your device.

Calendar

If you do not know the exact minute, any close time is fine — the hour pillar is what usually changes. An unknown hour is not guessed at here.

Gender

Used by the traditional calculation to set the direction of the luck cycles. Nothing else depends on it.

Used only to work out the local time zone and the longitude adjustment for true solar time. It is never sent anywhere.

Enter a date, a time, and a birth place to cast the chart.

This calculation happens on your own device. Nothing you enter — date, time, or birth place — is sent to a server or stored anywhere. Closing the page discards it.

What this is, and what it is not

  • It is a calculation. The pillars, ten gods, hidden stems, stages, and cycles are derived from a published method, and the same input always gives the same chart.
  • It is not a reading. This tool casts the chart and stops there. It makes no claim about what will happen, and it does not describe your character.
  • The element count is a count. It says how many surfaces in the chart carry each element — not how much of that element you are.
  • Birth time matters, and is not guessed. If you do not know it, the hour pillar will be wrong. Some charts are cast with an assumed hour; this one refuses to silently invent one.

For entertainment and self-reflection only. This is a traditional chart, not a prediction, diagnosis, or professional advice.

Want it read?

Casting the chart is the mechanical part. Making sense of it — which patterns carry weight, and what to try next — is the written report.
