I am trying to get the number of days between two dates minus 1 to exclude
the start date.
Here is the formula i have with M2:M15 being my holidays.
=NETWORKDAYS(F1, G1, $M$2:$M$15)-1

My problem is when something is done early i get a negitave number and it
subtracts 1 like i told it to but i need to add one to Negative numbers.

Date due       Date Complete                    current formula            
should be
F                  J
1/4/2007       1/3/2007                            -3                        
        -1
1/4/2007       1/4/2007                             0                        
         0
1/4/2007       1/5/2007                             1                        
         1

Any help would be greatly appriciated.
