In September 1752, the British Empire adopted the Gregorian calendar. An eleven-day adjustment in 1752 was needed because one more day had been lost since the calendar was changed in 1582. The year 1751 began on 25 March and ended on 31 December 1751. The first day of the year was now January 1st and the last day was December 31st—the calendar we use today. Thus, 2 September 1752 was followed by 14 September 1752. In this way, the Julian calendar added one day between 1582 and 1752.
