The Gregorian calendar has 97 leap years every 400 years: Every year divisible by 4 is a leap year. However, every year divisible by 100 is not a leap year. However, every year divisible by 400 is a leap year after all. So, 1700, 1800, 1900, 2100, and 2200 are not leap years. But 1600, 2000, and 2400 are leapyears.

By dropping every leap year from 1700 through 1740 the eleven superfluous dayswould be omitted and from 1 Mar 1740 they would be in sync with the Gregorian calendar.(But in the meantime they would be in sync with nobody!)
