Chinese New Year is an important traditional Chinese holiday. In China, it is also known as the Spring Festival, the literal translation of the modern Chinese name. Chinese New Year celebrations traditionally ran from Chinese New Year's Eve, the last day of the last month of the Chinese calendar, to the Lantern Festival on the 15th day of the first month, making the festival the longest in the Chinese calendar. Because the Chinese calendar is lunisolar, the Chinese New Year is often referred to as the "Lunar New Year".

The origin of Chinese New Year is itself centuries old and gains significance because of several myths and traditions. Traditionally, the festival was a time to honor deities as well as ancestors. Chinese New Year is celebrated in countries and territories with significant Chinese populations, including Mainland China, Hong Kong, Macau, Taiwan, Singapore, Thailand, Indonesia, Malaysia, Mauritius, Philippines, and also in Chinatowns elsewhere. Chinese New Year is considered a major holiday for the Chinese and has had influence on the lunar new year celebrations of its geographic neighbors.
