This week, millions of people will be celebrating Chinese New Year.
This year is the year of the Pig!
People will eat lots of food, enjoy fireworks, wear special clothes and hang red lanterns to mark the occasion.
This year, Chinese New Year began on Tuesday 5 February 2019. The reason the new year falls at this time is because it marks the start of the lunar new year, which is when there is the start of a new moon.
Because it depends on the moon, the date of Chinese New Year actually changes each year, but it will always fall some time between 21 January and 20 February.
In Chinese tradition, each year is named after one of twelve animals, which feature in the Chinese zodiac. Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig.
So the animals will have a year dedicated to them once every 12 years, in a cycle.
