BaZi calculator
Your Four Pillars of Destiny chart, calculated the way it was meant to be: exact solar terms, your birthplace's historical time zone, and true solar time. Then explained in plain English.
What you get
- Four pillars — year, month, day and hour, each with its Heavenly Stem and Earthly Branch (zodiac animal), plus the hidden stems inside each branch.
- Your Day Master — the element at the centre of your chart, with its archetype (the ten Day Masters).
- Five Elements balance — how much Wood, Fire, Earth, Metal and Water your chart holds, and which elements balance you.
- Ten Gods — the roles the other elements play relative to you: Mentor, Artist, Steward, Guardian and so on.
- Interactions — combinations, clashes and harmonies between your pillars, explained.
Why accuracy matters
Most online BaZi calculators quietly assume Beijing time, ignore daylight saving, and switch the year at Chinese New Year. Each of those shortcuts gives some people the wrong chart. FateBook:
Uses the exact solar terms. The year and month pillars turn at the precise instant of each 节气, computed for your actual moment of birth anywhere in the world.
Knows your birthplace's time zone — historically. Daylight-saving rules change; FateBook applies the rules that were in force on your birth date.
Uses true solar time. The day and hour pillars follow the sun at your birthplace, corrected for longitude and the equation of time.
Never lets AI do arithmetic. The chart is deterministic. AI is used only to write readings from the calculated chart.
