Subtracting dates: 8/31/05-8/1/05?

I am trying to subtract the current date from the last business day of the month, both being business days only.

So today is 7/26/05 and last business day is 7/29/05, so 7/29/05-7/26/05 = 3 days.

I have one cell with the current date. So that cell minus last business day equals the balance of the month. Any help is appreciated, thanks.

Try this
=ABS(NETWORKDAYS(A1,A2))-1
