How do I calculate business days without using the analysis

Is it permissible to use a UDF (User Defined Function)? It would
get
distributed with the workbook.

I had written one for just such an issue, and it basically mimics
the
Workday
Function.

If that would be helpful, I'd be happy to post it again.

To enter, <alt<F11 opens the VB Editor.

Ensure your project is highlighted in the Project Explorer window, then
Insert/Module and paste the code below into the window that opens.

To use, enter =WD(start_date, num_days, [holidays]) into some cell.

The optional 'holidays' argument must be entered as a cell (range) reference,
however.

==================================
Function WD(StartDate As Date, ByVal NumDays As Long, _
Optional Holidays As Range = Nothing) As Date

'Workday function without Analysis Toolpak
'However, Holidays must be in a range

Dim i As Long
Dim TempDate As Date
Dim c As Range
Dim Stp As Integer

Stp = Sgn(NumDays)
TempDate = StartDate
For i = Stp To NumDays Step Stp
TempDate = TempDate + Stp
If Weekday(TempDate) = vbSaturday Then _
TempDate = TempDate + Stp - (Stp 0)
If Weekday(TempDate) = vbSunday Then _
TempDate = TempDate + Stp + (Stp < 0)

If Not Holidays Is Nothing Then
Do Until Not IsError(Application.Match(CDbl(TempDate), Holidays, 0)) = False
If IsError(Application.Match(CDbl(TempDate), Holidays, 0)) = False Then
TempDate = TempDate + Stp
If Weekday(TempDate) = vbSaturday Then _
TempDate = TempDate + Stp - (Stp 0)
If Weekday(TempDate) = vbSunday Then _
TempDate = TempDate + Stp + (Stp < 0)
End If
Loop
End If
Next i

WD = TempDate
End Function
