What this system examines
Bazi uses the Four Pillars to examine natal structure, elemental balance, and the wider timing context around a present concern.

Calculation rules / A practical boundary
Calculate your Four Pillars, Day Master, and Five Elements from your birth date and time. Review the calculation settings alongside your chart.
This is a transparent traditional calculation, not proof, prediction, or personal advice.
The calculator runs in this tab. Your birth details are not saved or sent unless you choose to attach the result to a conversation below.
Do not use this tool as the basis for medical, legal, financial, safety, or relationship decisions.
How this system reads
How the result is formed
Birth date, recorded time precision and time zone determine the pillars. The separate free calculator shows the inputs and calculation version; an unknown birth time leaves the hour pillar unset.
How to read it responsibly
Birth-time uncertainty can change the hour pillar, so the input must be shown and correctable. Bazi describes a traditional interpretive framework, not a fixed destiny.
The other systems
Then ask one question about it
A chart on its own is the facts. A reading answers the question you bring, points at the exact card, line or palace it reads from, and can be written again with a second system beside it.
