New Year's Day

New Year's Day is a festival observed in most of the world on January 1, the first day of the year in the modern Gregorian calendar. January 1 is also New Year's Day on the Julian calendar. but this is not the same day as the Gregorian one. Whilst most solar calendars (like the Gregorian and Julian) begin the year regularly at or near the northern winter solstice, cultures that observe a lunisolar or lunar calendar celebrate their New Year (such as the Chinese New Year and the Islamic New Year) at less fixed points relative to the solar year.
