Count of workdays between 2 dates

Here is what I am trying to do:
Input: Start Date and End Date. Return the count of days between those two days, not including weekends (DO NOT count Saturdays or Sundays). I DO need to include holidays in the count.
Any help would be greatly appreciated!
Thanks
Tim
