There are 52 weeks in a typical year.
Yet, because a year is not an exact multiple of 7 days (7 days x 52 weeks = 364), there is an extra 1 day left over for standard years and 2 days for leap years.
Weeks in a common years
A common year has 365 days, so by dividing 365 by 7 (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday), the result is exactly 52.142 weeks.
(365 days) / (7 days/week) = 52.143 weeks = 52 weeks + 1 day
We can consider the number of weeks in a standard year: 52 weeks + 1 day.
Weeks in leap years
A leap year has 366 days, so dividing by seven days a week will result in 52.285 weeks. This is why a leap year is precisely 0.143 weeks longer than a regular year.
(366 days) / (7 days/week) = 52.286 weeks = 52 weeks + 2 days
We can consider the number of weeks in a standard year: 52 weeks + 2 days.
The next leap years are 2028 and 2032.
2024 is a leap year with 366 days, resulting in 52 weeks and 2 days.
