January 1st
January 1 is the 1st day of the year in the Gregorian calendar. There are 364 days remaining until the end of the year (365 in leap years). The preceding day is December 31 of the previous year. January 1 is the first day of the calendar year in both the Julian and Gregorian calendars. Here a calendar year refers to the order in which the months are displayed, January to December. The first day of the medieval Julian year was usually a day other than January 1. This day was adopted as the first day of the Julian year by some European countries between 1522 and 1579 (that is, before the creation of the Gregorian calendar in 1582). See beginning of the year. The British Empire (including its American colonies) did not adopt the Gregorian calendar until 1752. This change can lead to dating confusion between Old Style and New Style dates. The Gregorian calendar as promulgated in 1582 did not specify that January 1 was to be either New Year's Day or the first day of its numbered year. Although England began its numbered year on March 25 (Lady Day) between the 13th century and 1752, January 1 was called New Year's Day, which was a holiday when gifts were exchanged.
