Different months have different lengths - for example, January has 31 days, and June has 30. February has 28 (outside of leap years), which means it is exactly four weeks long. Obviously a month that is 30 days will be four weeks and two days, and one that is 31 days long will be four weeks and three days - or a little over four and a half weeks.
Four weeks and five days.
