Free BaZi Calculator — Four Pillars of Destiny

BaZi is a traditional Chinese system that maps your birth year, month, day and hour into four pairs of Heavenly Stems and Earthly Branches — eight characters in total. It reads personality patterns, elemental balance and life timing from the Five-Element interactions among those characters. It is an interpretive cultural system, not a scientific prediction.

Yes. Casting the chart — four pillars, hidden stems, Nayin, Day Master strength, Ten Gods distribution and Five-Element balance — is completely free and computed locally in your browser. No sign-up is required, and your birth data never leaves your device.

The hour pillar is one of the four pillars and governs the later chapters of life, children and inner aspirations. Without it, the chart has only six of its eight characters. If you do not know your time, the calculator still casts a three-pillar chart and marks it accordingly.

This page uses standard clock time (UTC+8) as entered. The full BaZi Xuan app applies true solar time correction based on your birthplace longitude and the equation of time, which matters if you were born near a pillar boundary or far from the 120°E meridian.

Western astrology reads planetary positions in the zodiac; BaZi reads the Five-Element composition of your birth moment expressed as stems and branches. Both are symbolic timing systems. BaZi focuses on elemental structure and luck cycles; this site also offers a daily Western horoscope computed from real ephemeris data.
