Chinese New Year, known in China as the SpringFestival and in Singapore as the LunarNewYear, is a holiday on and around the new moon on the first day of the year in the traditional Chinese calendar. This calendar is based on the changes in the moon and is only sometimes changed to fit the seasons of the year based on how the Earth moves around the sun. Because of this, Chinese New Year is never on January1. It moves around between January21 and February20.
