This formula will give you the number of weekdays Monday through Friday
which fall in the date interval A1 to B1 inclusive:

=SUMPRODUCT(INT((B1-A1+WEEKDAY(A1-{2,3,4,5,6}))/7))

The bracketed array constant gives the Weekday numbers associated with days
Monday through Friday. Change the bracketed array constant to get a count
for other sets of days. For example, use {1,7} for weekend days (Saturdays
and Sundays), or {2,4,6} for Mondays, Wednesdays, and Fridays.

This does not account for holidays. If you need to do this, prepare a list
of holidays and reply back for more help. (Although I don't use NETWORKDAYS,
I'm sure you'd have to do this in that case too).

Hello



Is there a way you can calculate working days between two days rather that
all days?



Thanks
