This could be achieved by dropping one leap year from the This would dictate 969 leap years every 4000 years, rather than the 970 leap years It has been suggested (by the astronomer John Herschel (1792-1871) among others) that a betterДЄpproximation to the length of the tropical year would be 365 969/ 4000 days =ДЈ65.24225 days. However, every year divisible by 400 is a leap year after all. However, every year divisible by 100 is not a leap year. The Gregorian calendar has 97 leap years every 400 years:Д®very year divisible by 4 is a leap year. The approximation 365 97/ 400 is achieved by having 97 leap years every 400 Thus it takes approximately 3300 years for the tropical year to shift one day In the Gregorian calendar, the tropical year is approximated as 365 97/ 400Дays = 365.2425 days.
