It was the intention that starting 1700 they would omit leap years until they were in sync with the Gregorian calendar. So 1700 was not a leap year. But they forgot about that or something and they made 1704 and 1708 leap years, so they did not gain on the Gregorian calendar and were one day out of sync with the Julian calendar. In 1712 they got back in sync with Julian by adding a February 30. They finally changed later that century (1768 if I remember right).
