Excel公式获得时差

Question

Checking out a formula that can take the difference of the time schedule. I have

=ABS(TRIM(LEFT(M2,8))-TRIM(RIGHT(M2,8)))*24

but it doesn't take into consideration the hours that will go beyond 12AM (the next day). Example on the second row (4:00 PM - 12:00 AM). I am only interested with the time that it elapsed from the start time to the end time, which is supposed to be 8, but the result is different because of the difference in the date. Any suggestions without adding a date column?

Answer 1

You need to add 1 to the time when it goes to the next day.

=IF(MID(M2,FIND("-",M2)+2,LEN(M2))<LEFT(M2,FIND("-",M2)-1),1,0)+MID(M2,FIND("-",M2)+2,LEN(M2))-LEFT(M2,FIND("-",M2)-1)
