# How many Weeks are in a Year?

## Weeks in a year calculation

One Gregorian calendar year has approximately 52 weeks.

### Weeks in a common Year

One Gregorian calendar common year has 365 days:

1 common year = 365 days = (365 days) / (7 days/week) = 52.143 weeks = 52 weeks + 1 day

### Weeks in a leap year

One Gregorian calendar leap year occures every 4 years, except for years that are divisable by 100 and not divisable by 400.

One Gregorian calendar leap year has 366 days, when February has 29 days:

1 leap year = 366 days = (366 days) / (7 days/week) = 52.286 weeks = 52 weeks + 2 days
