Exclude weekends from date difference

[nitinjoshi123]

Hi all
This is my second post for the same query. I wanted to calculate the difference between dates, excluding the weekends. Please see my thread 'Calculate difference between dates excluding weekends'. After much discussion, daddylonglegs suggested a brilliant formula =NETWORKDAYS(A1,B1)+IF(NETWORKDAYS(A1,A1)+ NETWORKDAYS(B1,B1)=2,-SIGN(NETWORKDAYS(A1,B1)),0) that seemed to be working fine. However, I had a problem today with this formula when my start day was saturday (24/05/08) and the last day was monday (26/05/08). What i want is that when i take the difference between these two days, i should get zero as answer as we are not including the weekends in calculation so the start date should ideally be the first weekday which is Monday. However, the formula is giving me 1 as an answer.
This formula works fine if i select 27/05/08 as last date in which case i get 2 as an answer which is right. In gist, what i am looking for is a formula which will give me the difference between two dates and exclude the weekends from the calculation. The last date can't be a weekend, but the start date can. Hence, whenever the start date is a weekend, the formula should take monday as a start day.
Many many thanks in advance
Cheers

Actually, it should be 1 day if the last date is 27/05/08 and not 2 days
