Working day counts vary by country. The 250-day figure applies to the United States. Countries with more public holidays (e.g. India, Germany) will have fewer net working days.
What Is a Leap Year?
A leap year has 366 days instead of 365. The extra day — February 29 — is added to keep the calendar synchronized with Earth's orbit around the Sun.
Gregorian Leap Year Rules
- A year is a leap year if it is divisible by 4 — e.g. 2024, 2028.
- Exception: Years divisible by 100 are not leap years — e.g. 1900, 2100 are not leap years.
- Exception to the exception: Years divisible by 400 are leap years — e.g. 2000 was a leap year.
2024
Divisible by 4 → Leap year
2100
Divisible by 100 → Not a leap year
2000
Divisible by 400 → Leap year

Frequently Asked Questions
How many days in a year exactly?
A mean tropical year — the time Earth takes to complete one orbit around the Sun — is approximately 365.2422 days. The Gregorian calendar rounds this to 365 days in a common year and adds one extra day (366 days) every four years in a leap year to stay aligned with the astronomical year.
Is 2026 a leap year?
No. 2026 is not a leap year. It has 365 days. The next leap year is 2028, which will have 366 days.
How many days in a year without weekends?
In 2026, there are 261 weekdays (Monday through Friday) and 104 weekend days (Saturday and Sunday). After subtracting 11 US federal holidays that fall on weekdays, there are approximately 250 net working days.
How many days are in each month?
January 31, February 28 (29 in a leap year), March 31, April 30, May 31, June 30, July 31, August 31, September 30, October 31, November 30, December 31.
Why do we have leap years?
We have leap years to keep the calendar aligned with Earth's orbit around the Sun. Because Earth takes approximately 365.2422 days to orbit the Sun, adding one extra day every four years compensates for the roughly 0.25-day discrepancy that would otherwise accumulate — causing the calendar to drift out of sync with the seasons over time.
