The macro below does not take days into consideration. For example, given a start date of 10/31/93 and an end date of 11/2/93, one month is returned. This function can be useful in determining the number of months that have passed since a particular starting date.

   Sub MAIN
      dtEDate = DateValue("1/23/93")
      dtLDate = DateValue("11/2/93")
      intMonths = (Year(DtLDate) - Year(DtEDate)) * 12 + Month(DtLDate) \ 
      - Month(DtEDate)
      MsgBox Str$(intMonths) + " months"
   End Sub 

For example, the following macro returns the number of months from 11/2/89 to the current date:

   Sub MAIN
      dtEDate = DateValue("11/2/89")
      intMonths = (Year(Today()) - Year(DtEDate)) * 12 + Month(Today()) \ 
      - Month(DtEDate)
      MsgBox Str$(intMonths) + " months"
   End Sub
