1712 (MDCCXII) was a leap year starting on Friday of the Gregorian calendar and a leap year starting on Tuesday of the Julian calendar, the 1712th year of the Common Era (CE) and Anno Domini (AD) designations, the 712th year of the 2nd millennium, the 12th year of the 18th century, and the 3rd year of the 1710s decade. As of the start of 1712, the Gregorian calendar was 11 days ahead of the Julian calendar, which remained in localized use until 1923.

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 (from Saturday, March 1) 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.
