Is Chinese astrology the same as the Chinese zodiac?

No. The Chinese zodiac is primarily an animal-year label. A Bazi chart uses four pillars — year, month, day, and hour — so it carries much more information than a single zodiac animal.

Why does the calculator ask for my birth location?

Birth location supplies longitude and the historical time-zone context needed for the calculator's true solar time method. That correction can matter near a pillar boundary, especially for the Hour Pillar. Read the true solar time method.

Can I use the Chinese astrology calculator without signing up?

Yes. Generating the deterministic chart is free and does not require an account. Sign-in is only needed for optional private features such as saving charts or using account-based reading features.

Chinese astrology, clearly defined

A full Bazi chart is more than a zodiac animal

The popular Chinese zodiac labels an animal year using Lunar New Year. Bazi uses four pillars and a solar-term boundary, including Lichun (Start of Spring) for the Year Pillar. This page keeps those conventions separate so a boundary date is not given a misleading single answer.

Looking only for an animal-year answer? Read the existing Chinese zodiac guide first.

About your birth details & sources

Used for this site's Luck Pillar direction convention (with the birth year's yin/yang stem) and some gender-dependent symbolic-star (shen sha) rules, such as Yuan Chen.

Enter the recorded local time, or mark it unknown. We never assume a birth time. For unknown time, a noon reference is used internally only to place the Day pillar; Hour Pillar and precise timing are withheld.

Birth times follow the linked Astro-Databank entries (source rating AA); chart accuracy depends on those records.
