I need a formula that will calculate the total time in Whole Hours & Percent of Hour.

It also needs to calculate over Midnight - 20:00 hrs to 01:30 hrs which should equal 5.5 hrs total time.

I have read through some similar issues but cannot find anything to covers the over midnight part.

I am using Office 2008 for MAC.



Thanks in advance.

The over midnight calculation can be obtained using =MOD(end_time-start_time,1)

Astonishing as this is a well known problem

What do you mean by "Whole hours and % of an hour". What should the result look like?

So if the time on site is equal to 5 hours and 30 minutes, the answer I am needing is 5.5 hours or 3 hours and 15 minutes would be 3.25 hours.

Thanks.

Also forgot to add that the time format is in 24 hrs using 0":"00

To change sexagesimal to decimal, multiply by 24 and format as number

An alternative to what has already been mentioned is to use (in C1):

=((B1<A1)+B1-A1)*24

where A1 holds start_time and B1 end_time, and where C1 is formatted General.

Xor, I like your unpersonalized approach....
