Calculating time difference between two days capturing the overnight time.

Guys, help a blonde please :o).

Cell A1 - 01/07/07
Cell B1 - 3 PM
Cell C1 - 01/08/07
Cell D1 - 10 AM

I need a time difference (in minutes) between these 2 days (c+d) - (a+b) that subtratcs 990 minutes of overnight (talking 7.5 working day from 9 am to 5.30 pm).

How whould I do it keeping the data the way it's entered?


Thanks!

So the answer here should be 210 (minutes), right? Assuming you want the working time.

What would happen if you had a Friday to a Monday, I assume you'd want to exclude weekend hours too. One way to do that

=((NETWORKDAYS(A1,C1)-1)*("17:30"-"09:00")+D1-B1)*1440

format as general.

note: NETWORKDAYS requires Analysis ToolPak, assumption is that start times and dates are always within the working day

Thanks!

Works perfectly well. (My boss is impressed hee hee) :o).
