A month with more than 28 days will always have four weeks and part of another, even though there are no calendar months that have five full weeks. This is why a certain day of the week is commonly represented by five in a month.
Despite the fact that no month has five weeks, knowing which months have five Fridays, Saturdays, or Sundays might be helpful. The number of days in the month and the day of the week on which it begins must be known in order to make this determination.
The first two days will come up five times in a month of 30 days (April, June, September, and November). The first three weekdays appear five times for months with 31 days (January, March, May, July, August, October, and December).
With only 28 days, February typically has four days per week. However, the first weekday in February will happen five times on leap years.
