What Is the Chinese Zodiac?
The Chinese zodiac is a traditional East Asian system that assigns one of twelve animals to each of the twelve Earthly Branches to mark a person's birth year. The animals follow the fixed order of Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig, repeating in a 12-year cycle.
When these are combined with the 10 Heavenly Stems (Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui), the result is the Sexagenary Cycle, a 60-year cycle that returns to its starting point once every sixty years. This happens because the least common multiple of 10 and 12 is 60, and it is exactly why a person's 60th birthday is traditionally celebrated as completing one full cycle.
The zodiac is widely used in fortune-telling, compatibility, and naming customs. This calculator takes only your birth year and instantly shows your animal sign, your Heavenly Stem, and your full Sexagenary Cycle name.
Calculation Formula
The animal sign and the Heavenly Stem are found from the remainder of the birth year. We subtract 4 because the year 4 AD was a Jia-Zi (甲子) year, the start of the cycle.
Animal (Earthly Branch): (year − 4) mod 12
Heavenly Stem: (year − 4) mod 10
Let's work through 2026 as an example.
Earthly Branch: (2026 − 4) mod 12 = 2022 mod 12 = 6 → Horse (午)
Heavenly Stem: (2026 − 4) mod 10 = 2022 mod 10 = 2 → Bing (丙)
So 2026 is the year Bing-Wu (丙午), the 'Year of the Horse'. Index 0 begins with Rat (子) and Jia (甲).
