Figuring 24 Hours Per Day

[Jeff]

I am laying out a time sheet that has shop time, travel time, on site time,
break time, and travel time back to shop. I have this formula:

=(IF(C8="","",(E8-D8)+(G8-F8)+(M8-L8)+(I8-H8)-(K8-J8)))

It works great if you work during the day time, but if you work past
midnight it won't figure the hours in I8 (start time) and H8 (end time).

Can someone please help me out?

As I don't know what the rest of your data looks like, this is merely a best
guess. But if you're only concern is with I8 and H8, you could change that
part of formula to:
(I8-IF(H8<I8,H8+1,H8)

This would add in the extra 24 hours needed. One thing though, why are you
subtracting H8 (end time) from I8 (start time)? Wouldn't that result in a
negative amount of time?

The same formula but subtract (ending time - start time), and in cell format
select time 13:30. That should work.

Example:

Start Time Ending Time Hours
8:00 1:00 17
9:00 16:00 7
10:00 13:00 3
11:00 12:00 1

and in hours this formula: =HOUR(IF(B21<A21,B21+24-A21,B21-A21)) the cell
format to number.

Here is a solution I used for a similar issue.
=IF(C8>F8,((F8-E8+D8-C8)*24)+24,(F8-E8+D8-C8)*24)
C is begin time
F is end time
D&E are lunch out and Lunch in

The above formula tests if end time is less than begin time, and then adds
24 hours to the begin time if true. HTH

=(IF(C6="","",(E6-D6)+(G6-F6)+(M6-L6)+(IF(H6>I6,(I6+24)-H6,I6-H6)-(K6-J6))))
