FateMaster BaZi Calculator

FateMaster is an AI Chinese metaphysics workbench built on BaZi, the Four Pillars of Destiny, and Zi Wei Dou Shu, Purple Star Astrology.

The calculation is not the model's job. A deterministic rule engine derives every chart from birth date, time and coordinates, corrected to true solar time using each country's standard meridian across 124 countries. The starting age of each luck cycle is measured from the exact interval between the birth moment and the adjacent solar term, down to the second. Only once the chart exists does the language model step in, and only to explain it.

An agent decides which method fits the question: a natal chart for the long arc of a life, an I Ching hexagram through Liu Yao or Mei Hua Yi Shu for a question about right now. When something is missing it asks rather than guesses.

Available in English, Japanese, Korean, Simplified and Traditional Chinese, with reference guides for the heavenly stems, earthly branches, ten gods and shensha. Core readings are free and need no signup.
