Spring Festival, Chinese New Year, or Lunar New Year is the most important of the traditional Chinese holidays. It is commonly called "Lunar New Year", because it is based on the lunisolar Chinese calendar. The festival traditionally begins on the first day of the first month (Chinese: 正月; pinyin: zhēng yuè) in the Chinese calendar and ends with Lantern Festival which is on the 15th day. Chinese New Year's Eve is known as chú xī. It literally means "Year-pass Eve". Chinese New Year is celebrated in countries and territories with significant Chinese populations, such as Mainland China, Hong Kong, Taiwan, Macau, Vietnam, Singapore, Indonesia, Malaysia, and also in Chinatowns elsewhere. Chinese New Year is considered a major holiday for the Chinese and has had influence on the new year celebrations of its geographic neighbors, as well as cultures with whom the Chinese have had extensive interaction.
