How do I enter a formula that subtracts 2 dates and returns a number (days)
that does not include weekends?

=NETWORKDAYS(A2,A1)

A2 holds the later date, A1 holds the earlier one.

Use the networkdays function. You should enter the start and end dates using
the dates function.

If you have the Analysis ToolPak add-in installed:

A1 = start date
B1 = end date

=NETWORKDAYS(A1,B1)-1

If you don't have the ATP installed, try one of these:

=SUM(INT((WEEKDAY(A1-{1,2,3,4,5},2)+B1-A1)/7))-1

=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(A1&":"&B1)),2)<6))-1

Hello - I do not have the Analysis ToolPak but I did use your suggestion
below (=SUM(INT etc. and it seems to have worked. Could you provide me with
what this formula is stating so I can better understand?

Many thanks!

To be honest, I don't know the logic behind that particular formula, I just
know that it works. I know the "mechanics", but explaining the mechanics
won't help in understanding the logic (or, "why it works"). I'm not sure of
the original author, maybe Daniel Maher.

Because I don't know the logic of that formula, I prefer the other formula
because I do know the logic behind it.
