In the Gregorian calendar, New Year's Day is the first day of the calendar year, 1 January. Most solar calendars, such as the Gregorian and Julian calendars, begin the year regularly at or near the northern winter solstice. In contrast, cultures and religions that observe a lunisolar or lunar calendar celebrate their Lunar New Year at varying points relative to the solar year.
