How many weeks in 100 years?

Answer 1

There are 52 weeks in one year.

52 x 100 = 5200

There are actually a little bit more than 52 weeks in one year.

A non-leap year has 365 days. A period of 100 consecutive years will contain 24 or 25 leap years.

So 365 x 100 = 36500 days.

Add 24 or 25 leap years and you have 36524 or 36525 days.

Divide by 7 and you have 5217 weeks plus 5 or 6 days.
