1712
In the Swedish calendar it began as a leap year starting on Monday and remained so until Thursday, February 29. By adding a second leap day, Friday, February 30, Sweden reverted to the Julian calendar and the rest of the year was in sync with the Julian calendar. Sweden finally made the switch from the Julian to the Gregorian calendar in 1753. This year had 367 days.
