Does 12 months equal to 52 weeks?

No, 12 months do not equal 52 weeks precisely. In a calendar year, there are 52 weeks and one day. This is because a regular year has 365 days, which is 52 weeks and 1 day. However, in a leap year, which occurs every four years, there are 52 weeks and 2 days due to the extra day added in February.
