How Many Days in a Year?
A standard calendar year has 365 days. A leap year, which occurs every 4 years, has 366 days. Use the calculator below to count the exact days in any year.
The extra day in a leap year is added to February, giving it 29 days instead of the usual 28. Leap years are divisible by 4 — so 2024, 2028, and 2032 are all leap years.
To count the exact days in a specific year, set the start date to January 1 and the end date to December 31 of that year. This is useful for annual leave calculations, interest periods, and any duration tied to a full calendar year.
