    Excel Formula to Calculate Time Span Between Different Time Range.

    Hi;

    I am trying to calculate hours worked if time span fall between different time range.

    Range 1 Range 2 Range 3
    Start Time Finish Time Total Hours >14:00 and <16:00 >16:00 and <22:00 >22:00
    08:00 14:00 6 0 0 0
    08:00 15:00 7 1 0 0
    08:00 18:00 10 2 2 0
    10:00 17:00 7 2 1 0
    10:00 23:00 13 2 6 1
    12:00 02:00 14 2 6 4

    I can get the total hours worked by using the MOD Function = MOD(B2-A2,1)*24 but struggling on how to calculate number of hours if finish time falls between different time range.

    Any help will be much appreciated.

    Thanks
    Omer.

    Re: Excel Formula to Calculate Time Span Between Different Time Range.

    If you have total hours in C2 try this formula in D2 for hours between 14:00 and 16:00

    =MAX(0,MIN(B2,"16:00")-MAX(A2,"14:00"))*24

    and similar for 16:00 to 22:00

    =MAX(0,MIN(B2,"22:00")-MAX(A2,"16:00"))*24

    Then for hours after 22:00

    =MAX(0,MIN(B2+(B2<A2),1+(B2<A2))-MAX(A2,"22:00"))*24

    Thanks Daddylonglegs, much appreaciates. It works great.

    The only trouble i am having now is if it overlaps to next day, finding it difficult to get it to work.

    Following is what i am trying to achieve;


    Range 4 Range 5
    Start Time Finish Time Total Hours >23:00 and < 01:00 >01:00
    12:00 04:00 16 2 3


    Any help on this will be much appreciated.

    Thanks.

    overlaps to next day
    use 28:00 hour with celformat h:mm you see 4:00
    You can calculate with >23:00

    Thanks Popi, much appreciated. Your solution is great and It could do the job but I will need to create a helper column for it.

    Currently Data Entry are done on the Start and Finish Time so was hoping to find a formulae based solution rather than using a helper columns.

    Thanks.

    You don't need a helper column.
