Which means that 1700, 1800, and 1900 weren’t leap years, however 2000 was. This extra precisely displays the size of the photo voltaic 12 months.
-
A Extra Correct Photo voltaic 12 months: The Gregorian calendar makes use of a imply photo voltaic 12 months of 365.2425 days, a remarkably shut approximation to the precise photo voltaic 12 months.
