January 1, 1752
Calendar Reform Takes Effect
The Gregorian calendar (henceforth n.s. or "new style") replaces the Julian calendar (o.s. or "old style") throughout the British world. The first day of a new year changes from March 25 to January 1. The calendar is also made consistent with Europe by dropping 11 days, with September 2, 1752 being followed immediately by September 14.
