September 14 - 1752 - Britain Adopts the Gregorian Calendar
When Great Britain and her Empire officially adopted the Gregorian Calendar, the nation was aligning its calendar with that used across Europe. This meant everyone in Britain experienced the strange sensation of moving straight from September 2 to September 14, and "losing" 11 days. The rejection of the old Julian Calendar was first introduced by Pope Gregory XIII in 1582, making most nations in Europe on a different calendar from Britain for a century and a half. Yet the problems in calculating Easter present in the Julian Calendar was only getting worse, and Britain was separated from the Continent. Also, Britain had a series of political troubles, including a Civil War, an Interregnum, and a revolution, among much else. By the middle of the 18th century, Britain was forced to adopt the Gregorian calendar thanks to the Calendar Act of 1750. Led by Philip Stanhope, 4th Earl of Chesterfield, the act was supported by the wealthy, the merchants, and the foreign ambassadors. Many common people resented what losing 11 working days would do for their wages and their taxes. Every person still just went along with adopting the Gregorian Calendar.
