Chinese Zodiac Sign

To know your Chinese sign, use the year of birth of the person in the classic calendar. In Chinese astrology, the Chinese zodiac sign is deduced via a calculation of the year modulo 12 (result of the rest of the Euclidean division by 12).

There is a slight gap between the Chinese calendar and the western calendar, the beginning of the year (January) is usually still in the previous year in China, the Chinese New Year being the first day of a new moon, the change is between January 21st and February 19th.

Example: A person born in the middle of 2000 was born under the sign of the rabbit as $ 2000 \equiv 8 \mod 12 $ (because $ 166 \times 12 + 8 = 2000 $) and 8 is for Rabbit

While the zodiac signs are based on the position of the sun, and not too far from the 12 months of the year, in China, chinese signs uses the chinese calendar, that represent 12 animals, each associated to a year on a 12 year cycle.

Animals are: Monkey, Rooster, Dog, Pig, Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse and Goat
