I have a large spreadsheet in which a start date is captured in cell D10 and a start time in E10. The end date is captured in J10 and end time in K10. In column y I need the difference in hours such that I may total column y to give me the total in hours that the generator was utilised in a month.
I have tried concatenating then using a formula like :- =TEXT(x10-w10, "d:h:mm")
(j10 + k10) - (d10 + e10)
. The result is also a date to which you would apply the[h]:mm
format to make sureh
can go beyond 24. If you store them as something else, store them as dates instead. – GSerg
