The first day of the calendar year in the Gregorian calendar, 1 January. Cultures and religions that follow a lunisolar or lunar calendar celebrate their New Year at other points of the year. Japan celebrates New Year on 1 January, in accordance with the Gregorian calendar, instead of with the Chinese calendar that was in use until 1873.
