I am not sure if a similar questions has been posted before... I did search but couldnt find.

I need the difference between two dates/times field in hours or minutes.

Eg:

A1 B1
1/4/05 10:00 2/4/05 14:30

The result should be 13.5 hours, considering only 8 hrs per day, only business days and 8 to 5 workday.

Can you please help me with the right formula.
