Ganzhi Calendar
Convert a Gregorian date into the sexagenary year, month, day and hour pillars plus the zodiac animal
出生日期与时辰
年柱以立春为界，月柱以节气为界，日柱基于1900年1月1日（甲戌日）推算。立春按 2 月 4 日近似取整；实际立春落在 2 月 3 日的年份（如 2025 年 2 月 3 日 22:10），当天出生者需按当年立春时刻校正。

About this tool
The Ganzhi calendar converts a Gregorian date into the traditional sexagenary cycle:
- Year pillar: the stem-and-branch year, such as a jiazi year, with its zodiac animal
- Month pillar: the sexagenary month, bounded by solar terms
- Day pillar: the sexagenary day within the 60-day cycle
- Hour pillar: the double-hour stem and branch for a given time
- Four pillars: year, month, day and hour output together
When to use it
- Four Pillars analysis: working out the pillars of a birth date and time
- Traditional culture research: understanding the sexagenary calendar
- Zodiac lookup: finding the animal for a birth year
- Almanac checks: seeing the stems and branches for a particular date
Background
- Ten heavenly stems: jia, yi, bing, ding, wu, ji, geng, xin, ren and gui
- Twelve earthly branches: zi, chou, yin, mao, chen, si, wu, wei, shen, you, xu and hai
- Sixty-year cycle: the stems and branches pair up and repeat every 60 years
- Zodiac pairs: rat, ox, tiger, rabbit, dragon, snake, horse, goat, monkey, rooster, dog and pig follow the branches in order
