The Chinese lunar calendar dates from 2637 BC. It was introduced by the Emperor Huang Ti during the 61st year of his reign.
One complete cycle of the calendar takes 60 years to complete. Each cycle is made up of five simple cycles of 12 years, each of which are named for an animal in the Chinese zodiac: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog and Boar.
