Calculating hours:minutes from cells with date and time
Trying to calculate total time (preferably in minutes) spent at a task/site.
Arrival and departure "times" are written in date-time format - so (arrival) [2/28/19 9:15PM] in one cell/column and (departure) [3/1/19 2:25PM] in another cell/column.
If it helps, those cells were created by combining multiple columns - date +hour+minute+AM/PM
Suggestions please? Non data geek asking this question so please, explanations in non-geek greatly appreciated!
