The Monkey is ninth of the 12 animals in the recurring 12-year Chinese zodiac cycle. Every 12 years there is a Monkey year. (Interestingly, Monkey years are all multiples of 12 - from 12 AD, through 1200 AD, to now in 2016.)
In Chinese astrology, each year is associated with a Chinese zodiac animal sign and one the Five Elements: Gold (Metal), Water, Wood, Fire, or Earth. Both the sign and element of your birth year are said to affect your personality and destiny. Element-sign combinations recur every 60 years:
People born in a year of the Monkey are called "Monkeys" in China. Usually, if born in a multiple-of-12 year, like 1980, you're a Monkey.
However, Monkey years are generally dated by the Chinese lunar calendar (starting on Chinese New Year), so if you were born in January or February check below for whether you're a Monkey.
