New Year’s Day is observed annually on January 1. It is the first day of the year on the modern Gregorian calendar as well as the Julian calendar used in ancient Rome. With most countries using the Gregorian calendar as their main calendar, New Year’s Day is the closest thing to being the world’s only truly global public holiday, often celebrated with fireworks at the stroke of midnight as the new year starts. January 1 on the Julian calendar currently corresponds to January 14 on the Gregorian calendar, and it is on that date that followers of some of the Eastern Orthodox churches celebrate the New Year. New Year’s Day is also a postal holiday in the United States.
The Romans dedicated New Year’s Day to the two headed God Janus, the god of gates, doors, and beginnings for whom the first month of the year (January) is also named. After Julius Caesar reformed the calendar in 46 BC and was subsequently murdered, the Roman Senate voted to deify him on the 1st January 42 BC in honor of his life and his institution of the new rationalized calendar. The month originally owes its name to the deity Janus, who had two faces, one looking forward and the other looking backward. This suggests that New Year’s celebrations are founded on pagan traditions. Some have suggested this occurred in 153 BC, when it was stipulated that the two annual consuls (after whose names the years were identified) entered into office on that day, though no consensus exists on the matter. Dates in March, coinciding with the spring equinox, or commemorating the Annunciation of Jesus, along with a variety of Christian feast dates were used throughout the Middle Ages, though calendars often continued to display the months in columns running from January to December.
Among the 7th century pagans of Flanders and the Netherlands, it was the custom to exchange gifts at the New Year. This was a pagan custom deplored by Saint Eligius (died 659 or 660), who warned the Flemings and Dutchmen not to. Most countries in Western Europe officially adopted January 1 as New Year’s Day somewhat before they adopted the Gregorian calendar. In England, the Feast of the Annunciation on March 25, was the first day of the new year until the adoption of the Gregorian calendar in 1752. The March 25 date was known as Annunciation Style; the January 1 date was known as Circumcision Style, because this was the date of the Feast of the Circumcision, considered to be the eighth day of Christ’s life, counting from December 25 when his birth is celebrated. This day was christened as the beginning of the New Year by Pope Gregory as he designed the Liturgical Calendar. Celebrations Are held world-wide on January 1 as part of New Year’s Day.
During the Middle Ages under the influence of the Catholic Church, many countries in western Europe moved the start of the year to one of several important Christian festivals – December 25 (the Nativity of Jesus), March 1, March 25 (the Annunciation), or even Easter. Eastern European countries (most of them with populations showing allegiance to the Orthodox Church) began their numbered year on September 1 from about 988. In England, January 1 was celebrated as the New Year festival, but from the 12th century to 1752 the year in England began on March 25 (Lady Day). So, for example, the Parliamentary record notes the execution of Charles I as occurring on January 30, 1648, (as the year did not end until March 24), although modern histories adjust the start of the year to January 1 and record the execution as occurring in 1649.
Most western European countries subsequently changed the start of the year to January 1 before they adopted the Gregorian calendar. Scotland changed the start of the Scottish New Year to January 1 in 1600. England, Ireland and the British colonies changed the start of the year to January 1 in 1752. the Gregorian calendar was introduced throughout Britain and the British colonies.
