This page deals with the annual event. For the band, see The New Year.
The New Year is an event that happens when a culture celebrates the end of one year and the beginning of the next. Cultures that measure yearly calendars all have New Year celebrations.
The most common modern celebrations are:
The ancient Roman calendar had only ten months and started the year on 1 March, which is still reflected in the names of some months which derive from Roman numerals: September (Seventh), October (Eighth), November (Ninth), December (Tenth). Around 715 BC the months of January, February and Mercedonius were added to the end of the year (Mercedonius in leap years only). Because consuls were chosen in January, and because years were named after the consuls who served in that year, January became the de facto beginning of the year. In 45 BC Julius Caesar introduced the Julian calendar, dropping Mercedonius and decreeing that the New Year should start on 1 January.
In the Middle Ages in Europe a number of significant feast days in the Ecclesiastical calendar of the Roman Catholic Church came to be used as the beginning of the year:
Since the 17th century, the Roman Catholic ecclesiastic year has started on the first day of Advent, the Sunday nearest to St. Andrew's Day (30 November).
Autumnal Equinox Day is "New Year's Day" in the French Republican Calendar, which was in use from 1793 to 1805. The French First Republic was proclaimed and the French monarchy was abolished on September 21, 1792, making the following day, Autumnal Equinox Day that year, primidi Vendemière, the first day of the "Republican Era" in France.
