The following sample Visual Basic for Applications macro calculates the number of months between 1/23/1993 and 11/2/1993:

   Sub Date_MonthsBetweenDates()
      Dim dBeginDate As Date
      Dim dEndDate As Date
      Dim intMonths As Integer
      ' Beginning date.
      dBeginDate = DateValue("1/1/1993")
      ' Ending Date.
      dEndDate = DateValue("2/1/1993")
      ' Calculate number of months between dates.
      intMonths = ((Year(dEndDate) - Year(dBeginDate)) * 12) + _
         Month(dEndDate) - Month(dBeginDate)
      ' Display number of months.
      MsgBox Str$(intMonths) & " month(s)"
   End Sub

NOTE: The number of months returned by this macro is not based on the exact number of days between the two dates. For example, given a start date of 10/31/1993 and an end date of 11/2/1993, the macro returns one month.
