    Formula count of hours between start/finish times

    Hello every body,

    I am creating a log of hours worked, so my input is start/finish times in hh:mm format, and I wish for excel to calculate automatically specific hours between start/finish times.

    example:
    start: 18:00
    finish 06:00

    night hours: I help in finding a formula to count the total hours 22:00 to 04:00 giving 6,0

    Any help appreciated

    In terms of night shift - if we assume B2 holds Finish and A2 start then:

    Assuming that shift could be any length up to 24 hours, e.g. even 03:00 until 22:30, for example, then try this formula in C2 where A2 is shift start and B2 shift end

    =MOD(B2-A2;1)*24-(A2>B2)*18-MEDIAN(4;22;B2*24)+MEDIAN(4;22;A2*24)

    format C2 as number to get decimal hours
