Chinese metaphysics, calculated
Everything on this site comes from calculation. Pillars are built from a lunisolar calendar; relationships are fixed by the element cycles and yin-yang polarity. The same input always gives the same result.

What is actually calculated
Chinese metaphysics begins by translating a moment of birth into eight characters. Those characters are not an interpretation — they are the output of calendar arithmetic. Layer two rules on top of them (the element cycles, and yin-yang polarity) and the relationships between the characters are fully determined.
This site stops at that calculation. It does not sort charts into fortunate and unfortunate, and it makes no claim about lifespan, illness, or how much money anyone will have.
Why the result never changes
Many fortune services tell the same person something different every time they ask. That cannot happen here. The pillars, the element relationships, and the Ten Gods are all products of fixed rules. If a reading changes from yesterday to today, it was invention, not calculation.
How to read this site
BaZi is not a machine for fixing the future. It is an old language for describing people and periods. When a day is described as sitting in the Wealth position, that does not promise income — it means matters around money are in motion.
