How to calculate the weeks in a month?

Each year has twelve months, and each month has a set number of days. Divide those days by 7 (days per week) to get weeks plus leftover days.

Months with 31 days (January, March, May, and others): 31 ÷ 7 = 4.4286 weeks = 4 weeks + 3 days.
Months with 30 days (April, June, September, and others): 30 ÷ 7 = 4.2857 weeks = 4 weeks + 2 days.
February in a common year: 28 ÷ 7 = 4 weeks exactly.
February in a leap year: 29 ÷ 7 = 4.1429 weeks = 4 weeks + 1 day.
