How many weeks in 3 months?

Answer 1

In weeks of 7 days, three months can be 12 weeks and 5 or 6 days, or 13 weeks, or 13 weeks and 1 day.

There are at least 4 weeks (28 days) in every month, but the number of days varies.

Some months have 30 days (April, June, September, November) and some have 31 days (January, March, May, July, August, October, December). These months can be arranged in either 5 or 6 calendar weeks, with at least three 7-day weeks in the middle.

February, with 28 days (29 in leap years), can be 4 or 5 calendar weeks.

Similarly, a period of three months can be either 89, 90, 91, or 92 days, arranged in at least 12 weeks of 7 days (84) or 13 weeks (91 days), with the largest possible number of separate calendar weeks being 15.

Answer 2

There are 12 to 13 weeks in three months (it depends on which months. A one month may have 30 or 31 days except Feb having 28 or 29 days).
