Question about algorithm for calculating dates that do not fall on weekend/holiday

[USTRAGNU1]

The post was an algorithm by Adezii.

[code]..
1.Public Function fCalcWorkDays2(dteStartDate As Date, lngNumOfDays As Long)
2. Dim lngCount As Long
3. Dim lngCtr As Long
4. Dim dteDate As Date
5.
6. lngCount = 0
7. lngCtr = 1
8.
9. Debug.Print "Date", "Day Count", "Weekday"
10.
11. Do
12. dteDate = DateAdd("d", lngCtr, dteStartDate)
13. Select Case Weekday(dteDate)
14. Case 7, 1 'Saturday and Sunday, do nothing
15. Case Else 'Monday thru Friday, OK
16. 'Is it a Holiday as posted in tblHolidays?
17. If DCount("*", "tblHolidays", "[Date] = #" & dteDate & "#") < 1 Then 'NOT Holiday
18. lngCount = lngCount + 1 'Increment Counter
19. Debug.Print dteDate, lngCount, Weekday(dteDate)
20. End If
21. End Select
22. lngCtr = lngCtr + 1
23. Loop While lngCount < lngNumOfDays
24. fCalcWorkDays2 = dteDate
25. End Function]

I work for the Air Force and I am trying to create a function that will do this very thing, but mine is adding too many days. Adezii's function looks much cleaner, but I do not understand a couple of items.

1. I don't understand how just typing "Case 7,1" on line 14 tells access to ignore Saturday and Sunday. Can someone explain that?

2. Also, can someone explain the purpose of the pound signs on line 17:

If DCount("*", "tblHolidays", "[Date] = #" & dteDate & "#") < 1 ?

Thank you for your assistance in this matter.
