However, during 1704 and 1708 due to the ongoing Northern War, Sweden's attention diverted from the calendar, allowing these years to remain leap years. To eliminate confusion, Sweden decided to revert to the Julian Calendar. (photo-Pixabay)

Thus, the day omitted in 1700 was added back in 1712. Since 1712 was inherently a leap year, it uniquely featured February 30. (photo-Pixabay)

However, due to technical glitches, the test flight scheduled for December 31 was canceled, and its prototype first took to the skies on January 1, 1981. In government records, this date is registered as December 32, 1980. (photo-Pixabay)
