Good Morning,

Have both date time combined and separated in excel.  Need to calculate both the median on the combined date/time and subtraction on the separated date/time.  Not sure what formula/formats to use.

See attached file.

Thanks
Nick

To get an actual time from A/B3 use:
=A3+TIMEVALUE(CONCATENATE(LEFT(B3,LEN(B3)-2),":",RIGHT(B3,2)))

To get an actual time for C/D3 use:
=C3+TIMEVALUE(CONCATENATE(LEFT(D3,LEN(D3)-2),":",RIGHT(D3,2)))

I'm sure there's more elegant, but basically you are creating a time from the time field, keeping in mind that sometimes the horus are 1 digit, sometimes there's 2 digits, and then adding it to the date.

From there you can use the usual "Median" or substracting two dates formulas.

Hello Nick,

For your subtraction try this formula for row 3 copied down

=TEXT(D3,"00\:00")+C3-TEXT(B3,"00\:00")-A3

format as [h]:mm

and for the median do you just want a median of all those values? If so try a simple MEDIAN function like

=MEDIAN(A14:B18)

see highlighted cells on the attached
