New Year's Day

calendar · traditions · winter

January 1st Start. New Year's Day falls on January 1st because the Gregorian calendar, used by most countries around the world, begins its year on this date. This calendar is based on the sun's path through the sky.

Winter Timing. The Gregorian calendar starts near the winter solstice, which is the shortest day of the year in the Northern Hemisphere. Many solar calendars, including this one, time their new year around this important sun event.

Lunar New Years Differ. Not all cultures celebrate their new year on January 1st. Some follow lunar or lunisolar calendars that track the moon's cycles, so their New Year celebrations happen at different times of the solar year.

Ancient Calendar Roots. The Gregorian calendar we use today was introduced by Pope Gregory XIII in the 1500s to improve upon the older Julian calendar and keep it aligned with Earth's actual orbit around the sun.
