The new year is
the time at which a new calendar year begins and the
calendar's year count increases by one.Many cultures celebrate the event in some manner and
the first day of January is often marked as a national holiday.In the Gregorian calendar, the most widely used calendar
system, New Year occurs on Jan. 1 (New Year's Day). This was also the case both
in the old Roman calendar (at least after about 713 BCE) and in
the Julian calendar that succeeded it.
