Swedish calendar, 1700–1712
About the Swedish calendar, 1700–1712
Sweden planned to reach the Gregorian calendar gradually by omitting every leap day from 1700 to 1740. It dropped the 1700 leap day but then kept the next ones during the Great Northern War, leaving it out of step with both systems. In 1712 it returned to the Julian calendar by adding a 30 February, the only one ever officially used. Sweden finally switched in 1753, following 17 February with 1 March.
