What is the formula used? I am trying to do this in an excel sheet. I have the military time of start and finish and need the number of hours and minutes for a task (actually about 400 of them!)

If I wanted to log this on an excel sheet, how would I do this? so I could just type the times started and finished, to = my hours and minute worked that day.

for example

7.27 5.06 =
8.25 6.27 =

Does this not like hours after midnight? It's telling me there is 8:40:00 between 09:15 and 00:35. I was hoping this would be faster then doing all the math but not so far...
