On average there are about 4.3 weeks in a month. Each week is 7 days, and there are normally either 30 or 31 days in a month, so there are usually between 4.2 and 4.4 weeks per month. The exception is February because it has fewer days, so there are about 4 weeks in that month. On average there are about 4.3 weeks in a month.
Weeks in a month calculation. For 31 days in a month: (31 days) / (7 days/week) = 4.4286 weeks = 4 weeks + 3 days. For 30 days in a month: (30 days) / (7 days/week) = 4.2857 weeks = 4 weeks + 2 days. For 28 days in a month: (28 days) / (7 days/week) = 4 weeks.
