Hi, I have used the below WorkingDays function to calculate the number of weekdays between two dates (excluding holidays referenced from a table called tblHolidays). It appears the function does not always calculate the days correctly and is out by a day. Is there a way of full proofing this?

' Comment: Accepts two dates and returns the number of weekdays between them
' Note that this function has been modified to account for holidays. It requires a table
' named tblHolidays with a field named HolidayDate.
