The Chinese New Year, which is also called the Lunar New Year, is a celebration that takes place at the start of each new year on the traditional Chinese lunisolar calendar. The Spring Festival (traditional Chinese: simplified Chinese: pinyin: Chnjié) is a common name for the celebration in Chinese. This name can be written in either traditional or simplified Chinese. Since lichun is usually the first day of spring on the lunisolar calendar, the festival celebrates the first of the twenty-four solar terms around the time of the Chinese New Year. This is because lichun is the first of the twenty-four solar terms. Observances traditionally begin on New Year's Eve, the evening prior to the first day of the year, and continue through the Lantern Festival, which is held on the 15th day of the year. These celebrations serve to mark the end of winter and the beginning of the spring season. The new moon that occurs between the 21st of January and the 20th of February marks the beginning of the first day of the Chinese New Year.
