How many whole weeks is in a month?

A month typically has about 4.3 weeks, as there are 30 or 31 days in most months, which equates to roughly 4 weeks and 2 or 3 days. However, February usually has 4 weeks, except in leap years when it has about 4 weeks and 1 day. Therefore, while most months contain 4 whole weeks, some have a little extra.
