Chinese New Year is an important traditional Chinese holiday celebrated at the turn of the Chinese calendar. In China, it is also known as the Spring Festival, the literal translation of the modern Chinese name. Chinese New Year celebrations traditionally run 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".
Chinese New Year is 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 neighbours.
Within China, regional customs and traditions concerning the celebration of the Chinese new year vary widely. Often, the evening preceding Chinese New Year's Day is an occasion for Chinese families to gather for the annual reunion dinner. It is also traditional for every family to thoroughly cleanse the house, in order to sweep away any ill-fortune and to make way for good incoming luck. Windows and doors will be decorated with red color paper-cuts and couplets with popular themes of "good fortune" or "happiness", "wealth", and "longevity." Other activities include lighting firecrackers and giving money in red paper envelopes.
