Quick Answer & Understanding Your Result
A Chinese Zodiac Calculator determines your traditional 12 Animal Sign (Shengxiao) and Five Elements (Wu Xing) using the East Asian sexagenary lunar calendar cycle.
The 12 Animal Earthly Branches (Địa Chi)
- Rat (Tý), Ox (Sửu), Tiger (Dần), Rabbit/Cat (Mão), Dragon (Thìn), Snake (Tỵ).
- Horse (Ngọ), Goat (Mùi), Monkey (Thân), Rooster (Dậu), Dog (Tuất), Pig (Hợi).
The 5 Elements & Polarity (Ngũ Hành)
- Wood (Mộc), Fire (Hỏa), Earth (Thổ), Metal (Kim), Water (Thủy) paired with Yin or Yang polarity in a 60-year repeating cycle.
- Lunar New Year Cutoff: If born in January or early February before Tết, your zodiac belongs to the previous lunar calendar year.
Enter your birth year above to calculate your exact Zodiac Animal and Element instantly.
Formula & Calculation Logic
Mathematical FormulaSexagenary mathematical calculation:
- Modulo 12 determines the 12 animal branches starting with Rat (index 1).
- Modulo 10 determines the 10 heavenly stems representing the 5 elements with Yin/Yang polarity.
