   Sub Main
      'This macro determines the number of days in a given month.
      datev = DateValue(InputBox$("Enter a date in the mm/dd/yy format"))
      mon = Month(datev)
      Select Case mon
         Case 1, 3, 5, 7, 8, 10, 12
            MsgBox "31 days"
         Case 4, 6, 9, 11
            MsgBox "30 days"
         Case 2
            mon = Month(datev)
            If Year(datev) Mod 4 = 0 Then
               MsgBox "There are 29 days in this month"
            Else
               MsgBox "There are 28 days in this month"
            End if
      End Select
   End Sub

This macro prompts for a date in the mm/dd/yy format and returns the number of days in the specified month. The Month function is used to determine the month number for the specified date. Then depending on the month number (1-12), a message box posts the number of days in the month.

The macro takes leap years into consideration when computing the number of days in the month of February.


   If Year(datev) Mod 4 = 0 Then

The year is divided by 4 and if the remainder is 0, the number of days in the month is 29 days.
