(Excel 2000) (In the example below, the dates used are in MM/DD/YY format). In column A, I have certain dates and in column B also, I have dates as well (and these are later in time than those in col A). In col C, I calculate the difference by subtracting the value in col A from that in col B. For example, I may have 3/13/01 in A1, 3/20/01 in B1 and C1 will calculate the difference as 7. But the problem is: I DON'T want to include Saturdays & Sundays, only the weekdays! So in reality, the true difference between the 2 dates in the example above is 5 (i.e. 5 business days). The current formula I am using is (B1-A1); is there a way to modify it so that Saturdays & Sundays are not included in the difference?
