.NET Date Compare: Count the amount of working days since a date?

Question

What\'s the easiest way to compute the amount of working days since a date? VB.NET preferred, but C# is okay.

And by \"working days\", I mean all days excluding Satu

Answer 1

Here is a sample of Steve's formula in VB without the holiday subtraction:

Function CalcBusinessDays(ByVal DStart As Date, ByVal DEnd As Date) As Decimal

        Dim Days As Decimal = DateDiff(DateInterval.Day, DStart, DEnd)
        Dim Weeks As Integer = Days / 7
        Dim BusinessDays As Decimal = Days - (Weeks * 2)
        Return BusinessDays
        Days = Nothing
        Weeks = Nothing
        BusinessDays = Nothing

End Function
