Lunar New Year is the beginning of the new year based on the lunar calendar or lunisolar calendar. Lunar calendars follow the lunar phase while lunisolar calendars follow both the lunar phase and the time of the solar year. The event is celebrated by numerous cultures in various ways at diverse dates.

The more well-known celebrations include New Year's Day (or week) in the Chinese calendar and Tibetan calendar of East Asia;^[1][2][3] the Buddhist and Hindu calendars of Southeast and South Asia; the Islamic calendar and the Jewish calendar that originated in the Middle East; and the Nisga'a calendar from Canada. The determination of the first month of a new lunar year varies by culture.
