Access 2010 VBA Function Calculate Workdays

I'm using the code below to calculate workdays and I'm try to figure out how to incorporate holidays in the function. Any suggestions??

 Dim WholeWeeks As Variant
      Dim DateCnt As Variant
      Dim EndDays As Integer

      BegDate = DateValue(BegDate)
      EndDate = DateValue(EndDate)
      WholeWeeks = DateDiff("w", BegDate, EndDate)
      DateCnt = DateAdd("ww", WholeWeeks, BegDate)
      EndDays = 0
      Do While DateCnt < EndDate
         If Format(DateCnt, "ddd") <> "Sun" And _
                          Format(DateCnt, "ddd") <> "Sat" Then
            EndDays = EndDays + 1
         End If
         DateCnt = DateAdd("d", 1, DateCnt)
      Loop
      Work_Days = WholeWeeks * 5 + EndDays

You need to add a table of holidays, then check the dates as you add if it's a holiday or not.  Only way to do it.

You can optimize a bit; get a recordset of holidays between start and end, sorted in ascending sequence.  Then check on each iteration of the loop, and if = skip and fetch the next holiday record.

the other way to do it of course is to simply count the number of holidays between start and end and subtract at the end.

Work_Days = WholeWeeks * 5 + EndDays  - Dcount("*","tblHolidays","[HolidayDate] Between #" & Format$(BegDate,"MM/DD/YY")  & "#  AND #" & Format$(EndDate,"MM/DD/YY") & "#")

 assuming tblHolidays only contains dates that are not Saturday or Sunday.
