Just as there is a Western Zodiac which is made up of twelve signs based on various constellations in the night sky, there is a Chinese Zodiac. The Western Zodiac has twelve signs which are assigned to each month out of the year. The Chinese Zodiac assigns a sign to each year in a 12-year cycle. One of those signs is the sign of the Monkey.
The yearly cycles in this zodiac are based on the orbit of the planet Jupiter, the largest planet in the solar system. It is a form of astrology followed in China, Japan, Korea, and other places like Nepal, Sri Lanka, and Vietnam.
The signs in Chinese astrology include the Monkey as well as the Rat, the Ox, the Tiger, Rabbit, Dragon, Snake, Horse, Goat, Rooster, Dog and the Pig. Each sign has particular traits just like Western signs have. When someone is born, they are born under the Chinese sign that dominates that year.
People who are born under the sign of the Monkey are born in the years 1920, 1932, 1944, as well as 1956, 1968, 1980 and 2016. The sign comes around once every twelve years so the next one will be 2028. It is the ninth sign of the Chinese zodiac.
Anyone who is born under the sign is usually smart and has a magnetic personality. They are curious and clever as well as jokers. The monkey is a smart animal and this is one reason intelligence is attributed to those born under the sign. In the early years of Chinese astrology, they called the Marquis of China Hou. This is the way the word for monkey is pronounced but the significance is that if the Marquis was a monkey then anyone born as one was under an auspicious sign.
As for good matches, anyone who is a Monkey would do well to be married to an Ox or a Rabbit. Both of these signs are made for the Monkey. They need freedom but they can tolerate one another. They also have lots of curiosity and have similar opinions regarding life.
Monkeys should avoid trying to get involved with tigers or pigs. These signs are not at all compatible because they do not have the patience for monkeys. They also tend to disrespect each other. This leads to conflicts and can influence the relationship in a bad way. You can read more about the traits of this animal sign here.
