Free BaZi Calculator

Your Four Pillars of Destiny — Year, Month, Day and Hour — calculated instantly from your birth time.

BaZi (八字), also called the Four Pillars of Destiny, is one of the oldest systems of Chinese astrology. It maps the heavenly stem and earthly branch of your birth year, month, day and hour into four "pillars" that describe your innate energy.

The Day Master — the heavenly stem of your birth day — represents you. Its element (Wood, Fire, Earth, Metal or Water) and how the other pillars support or drain it reveal your strengths, blind spots and the cycles of your life.

FateChart computes your raw BaZi chart for free, no account needed. When you want a deep, personalized reading of your wealth, career, relationships and luck cycles, an AI BaZi master is one click away.

Frequently asked questions

What information do I need for a BaZi chart?

Your birth date and, ideally, your birth hour. The hour determines the Hour Pillar; if you are unsure, you still get an accurate three-pillar reading.

Is the BaZi calculator free?

Yes. The full chart data — four pillars, Day Master, zodiac and elements — is free with no sign-up. Only the in-depth AI interpretation is a paid feature.

What is the Day Master?

The Day Master is the heavenly stem of your birth day. It represents "you" in the chart, and its element is the anchor for the whole reading.
