I need help on an Excel formula that will compute the SLA between 2 dates. NETWORKDAYS() doesn't include weekends and I need something that will include Saturday and Sunday.

Pardon my ignorance, but what is SLA (I searched, but it was ambiguous)? – jonsca Aug 15 '11 at 12:50
@slhck Yeah, that was my likeliest candidate, but I'm trying to figure out if all the OP needs is just the number of days between two dates... – jonsca Aug 15 '11 at 12:56
@slhck Thanks for bringing that one to my attention, though. – jonsca Aug 15 '11 at 13:03
Possibly Service Level Agreement e.g. in business scenarios there is often an SLA that correspondence will be replied to within a certain number of days – Kris C Aug 15 '11 at 13:08

If you're just looking for the number of days between two dates, just subtract them:

      A         B      C
1  11/4/10   =NOW()  =b1-a1

If there's a time involved (like when calling =NOW()) you will end up with a fractional component, but just round as required by your industry's rules.

Hi! Thanks for this but I used the DATEDIF() since I also need to calculate the time and not just the number of days. – user82087 Aug 17 '11 at 7:36
