Assuming...

A1 contains your start date
B1 contains your end date
C1:C10 contains your holidays

Try the following...

=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(A1&":"&B1)),2)<5),--(1-ISNUMBER(MATCH
(ROW(INDIRECT(A1&":"&B1)),C1:C10,0))))

....which calculates networking days from Monday through Thursday,
excluding the referenced holidays, and where Monday=1, Tuesday=2, etc.
Or, for more flexibility...

=SUMPRODUCT((WEEKDAY(ROW(INDIRECT(A1&":"&B1)),2)={ 1,2,3,4})*(1-ISNUMBER(M
ATCH(ROW(INDIRECT(A1&":"&B1)),C1:C10,0))))

Hope this helps!
