How the Chinese zodiac really works
The Chinese zodiac (shengxiao, 生肖) assigns one of twelve animals to each lunar year — Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig — in a cycle that has ordered birthdays, marriages, and fortunes for over two thousand years. Your animal is said to color your temperament, your luck, and your chemistry with the other eleven signs.
Here is the detail most quick lookups get wrong: the zodiac year begins at Chinese New Year, not January 1. Because the lunisolar calendar drifts against the Gregorian one, the new year falls anywhere from January 21 to February 20. Someone born on January 27, 1998 is an Ox, not a Tiger — the Tiger year only began on January 28. Our calculator uses the exact Chinese New Year date for every year from 1924 to 2043, so January and February birthdays land on the right animal.
Layered over the animals is the cycle of five elements — Wood, Fire, Earth, Metal, Water — each ruling two years in turn, plus an alternation of yang (even years) and yin (odd years). Together they form the classical 60-year cycle, which is why your precise combination, like “Yang Metal Horse,” recurs only once in a lifetime.

Frequently asked questions
- What is my Chinese zodiac sign?
- Your sign is the animal of the lunar year you were born in: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, or Pig, repeating every 12 years. Enter your exact birth date in the calculator above — the year alone is not enough if you were born in January or early February.
- Why does my birthday in January or February change my sign?
- The Chinese zodiac year begins at Chinese New Year, which falls on a different date each year between January 21 and February 20. If you were born before that year's new year, you belong to the previous animal. For example, Chinese New Year 1998 fell on January 28 — so a January 27, 1998 birthday is an Ox, not a Tiger.
- What are the five elements in the Chinese zodiac?
- Each year also carries one of five elements — Wood, Fire, Earth, Metal, or Water — from the cycle of ten heavenly stems, with each element governing two consecutive years. Combined with the 12 animals this creates the full 60-year cycle: 1990 was a Metal Horse year, 2024 a Wood Dragon year.
- What do yin and yang mean for my zodiac year?
- Years alternate between yang (even-numbered years) and yin (odd-numbered years), reflecting the alternating polarity of the heavenly stems. Yang years are traditionally associated with active, outward energy and yin years with receptive, inward energy — a subtle shading on top of your animal and element.
- Which Chinese zodiac signs am I most compatible with?
- Traditional astrology groups the twelve animals into four affinity trines of naturally harmonious signs: Rat-Dragon-Monkey, Ox-Snake-Rooster, Tiger-Horse-Dog, and Rabbit-Goat-Pig. Your two trine partners are considered your best matches, while the sign directly opposite yours on the wheel is your clash. Try our zodiac compatibility calculator for any pairing.
