New Year

New Year is the time at which a new calendar year begins and the calendar's year count increments by one. Many cultures celebrate the event in some manner. The New Year of the Gregorian calendar, today mostly in use, falls on 1 January (New Year's Day), as was the case both in the old Roman calendar (at least after about 713 BCE) and in the Julian calendar that succeeded it. The order of months was January to December in the Old Roman calendar during the reign of King Numa Pompilius in about 700 BCE, according to Plutarch and Macrobius, and has been in continuous use since that time. Many countries, such as the Czech Republic, Italy, Spain, the UK, and the United States, mark 1 January as a national holiday.

During the Middle Ages in western Europe, while the Julian calendar was still in use, authorities moved New Year's Day variously, depending upon locale, to one of several other days, among them: 1 March, 25 March, Easter, 1 September, and 25 December. These New Year's Day changes generally reverted to using January 1 before or during the various local adoptions of the Gregorian calendar, beginning in 1582. The change from March 25 – Lady Day, one of the four quarter days – to January 1 took place in Scotland in 1600, before the ascension of James VI of Scotland to the throne of England in 1603 and well before the formation of the Kingdom of Great Britain in 1707. In England and Wales (and in all British dominions, including Britain's American colonies), 1751 began on March 25 and lasted 282 days, and 1752 began on January 1.
