Free Chinese Metaphysics Tools and Calculators
These tools are for cultural reflection and self-exploration based on traditional Chinese metaphysics systems. They are not predictions, and results should be used as one of many inputs in personal reflection and planning. Everything runs in your browser, nothing needs an account, and the birth details you enter are never sent anywhere.
Quick Definition
BeyondBazi offers free tools across three traditions. Bazi Four Pillars: a full chart calculator with luck pillars, a two-chart compatibility tool, and a Bazi versus Zi Wei comparison. Feng shui and almanac: a daily almanac, an auspicious date finder across a range, a single date checker, and an Eight Mansions Kua number calculator. Zi Wei Dou Shu: a chart generator and an annual forecast. There is also a Day Master reflection quiz. All are free, need no signup, run entirely in your browser, and are built for reflection rather than prediction.
Bazi Four Pillars 八字
The Four Pillars chart converts a birth moment into eight characters across four stem and branch pairs. It is the foundation the rest of the site refers back to.

A note on how to hold all this. These systems came out of particular places and centuries, and they carried real weight in the households that used them. Treating them as harmless entertainment misses something, and treating them as certainties about a person or an outcome misses something else. The middle position, which is where these tools sit, is to take them seriously as a body of thought worth understanding, and to hold their conclusions loosely. If you want the background rather than the output, the articles cover where each system came from and how it is meant to be read.
