Chinese New Year or Spring Festival is the most important of the traditional Chinese holidays. It is often called the Lunar New Year, especially by people in mainland China and Taiwan. The festival traditionally begins on the first day of the first month in the Chinese calendar and ends on the 15th; this day is called Lantern Festival.
Chinese New Year's Eve is known as Chúxī. It literally means "Year-pass Eve". Celebrated in areas with large populations of ethnic Chinese, Chinese New Year is considered a major holiday for the Chinese and has had influence on the new year celebrations of its geographic neighbours, as well as cultures with whom the Chinese have had extensive interaction. These include Koreans, Mongolians, Nepalese, Bhutanese, Vietnamese, and formerly the Japanese before 1873. In Mainland China, Hong Kong, Macau, Taiwan, Singapore, Indonesia, Malaysia, the Philippines, Thailand and other countries or regions with significant Han Chinese populations, Chinese New Year is also celebrated, and has, to varying degrees, become part of the traditional culture of these countries.
