To account for this fractional distinction, we add an additional day to the calendar each 4 years, making a intercalary year with three hundred and sixty six days as a substitute of the standard 365.
With this understanding, let’s embark on a journey to uncover extra intriguing details about leap years…
what number of days in a intercalary year
A intercalary year happens each 4 years to maintain our calendar in sync with the Earth’s orbit across the Solar.
- 1 additional day added in February
- three hundred and sixty six days in a intercalary year
- Leap years divisible by 400
- Not divisible by 100 should not leap years
