Excel Formula Needed for Calculating Minutes

  Durko 14:06 10 Aug 2009

What excel formula do I use to create individual and total minutes for the below. e.g. A1 is start time and A2 is 9:00pm with same B1 end time and B2 9:45pm etc. Time can be formatted 9:00pm or 21:00.

Start time End time
9:00pm 9:45pm 45min
10:40pm 11:15pm
9:40am 10:15am
10:45pm 11:35pm
11:40pm 12:20am
10:20am 12:45pm
7:30pm 9:00pm
11:30pm 11:50pm
11:50pm 04:50am

Any ideas very welcome and sorry for the waffle.

Format Cell A1 as Custom then hh:mm
Format Cel1 B1 as Custom then hh:mm

Format Cell C1 as Custom then hh:mm

Enter in Cell C1 the formula B1-A1 then enter the formala B1-A1

As some of your times span midnight, in C1


Format your total cell as Custom [h]:mm
