紫微斗数 · 八字

The other half of astrology
was written in Chinese.

You know your star sign. But a thousand years before pop horoscopes, Chinese astronomers built Zi Wei Dou Shu — a destiny chart of 12 life palaces — and BaZi, the Eight Characters of your birth moment. Enter your birth details and read yours, in plain English, free.

The birth hour positions every palace in your chart — worth digging out of a birth certificate if you can. Without it we'll use an approximation.

°Ehours

Your birth hour is measured by the sun, not the clock — so where you were born nudges the true hour. Pick any city worldwide (or enter longitude + UTC offset) and we correct to local solar time. Leave blank to skip.Enter your standard-time hour: if you were born during daylight saving time your clock was one hour ahead — subtract one hour for precision.(Add a birth hour to apply this — an unknown hour has nothing to correct.)

Sex at birth

Classical chart rules differ by yin/yang polarity, which is set by birth sex.

紫微斗数

The Purple Star chart

Zi Wei Dou Shu maps your life across 12 palaces — career, marriage, wealth, health — each seated by ancient stars. Vastly more detailed than a sun sign, and almost unknown in the West.

八字

Your Eight Characters

BaZi writes your birth moment as eight characters and reads your elemental makeup from them — the system Chinese families have consulted for major decisions for over a thousand years.
