How do I calculate business days without using the analysis Tool-Pak.

How does this problem differ from the question you posted a few hours ago, and
to which you not only received responses, but you also responded that Bob's
solution worked?

Wait for the next version of Excel, in which the ATP functions will be
integrated, I have understood.
Of course you can imitate the present BusinessDays functions of ATP, but it
sure is a lot of work.
What's your problem in using ATP?

Just to clarify, my last inquiry was to calculate the last business date
based on a given date. Now my current question is, how do I calculate
the business day from start date to end date w/o using the ATP. The
reason why I don't want to use the ATP is because not everyone who will
be viewing my file will have that add in.

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.

Hi Ron,

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

Just curious:

What made you that?

Same question was asked -- someone that wanted to use the Workday function, but
didn't want to install the ATP.

Best,

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
===================================
