Date Calculation question

[Amanda]

I was able to successfully use someone's help on this site to calculate the
following

Add 60 Calendar dates, excluding holidays with the holidays defined in a
hidden column. using the following formula:
A2-A1-COUNTIF(C1:C7,">"&A)+COUNTIF(C1:C7,">"&A2)...

While this excludes returning a Holiday date, it doesn't add days in lieu of
the Holiday for the returned date..example If I want to count 45 Calendar
days from 11/20/09, I do not want it to land on Thanksgiving or Christmas, I
want it two additional days if that occurs? How can I incomporate this in
the above formula?

Thanks,
Amanda

Why don't you just use Workday

=WORKDAY(A1,A2,C1:C7)

OP is not excluding weekends, only holidays.

Might be easier to do with a UDF (user-defined-function). Open up the VBE by
pressing Alt+F11. Then goto Insert - Module. Paste this in:

'========
Function ExcludeDays(Start_Date As Date, Days As Integer, _
Holidays As Range) As Date

If Days < 0 Then
ExcludeDays = "#VALUE!"
Exit Function
End If

Do While Days > 0
Start_Date = Start_Date + 1
For Each cell In Holidays
If Start_Date = cell.Value Then
'If a holiday, don't count
x = 0
Exit For
Else
'If not a holiday, count it
x = 1
End If
Next

Days = Days - x
Loop

ExcludeDays = Start_Date

End Function
'==============

Back in your worbook, your formula becomes:
=ExcludeDays(A1,60,C1:C7)
