Excel Start & Finish Time with with Operating Hrs each day

Hi All,

 

Need a solution for the below. i have start and finish time but it expands to approx 8-9 days. how do i calculate total hrs with only operating hrs which starts from 4:20 am and finish at next day 1 or 2 am. 

 

In below example i need actual value as my end result cant go with total which includes non operating hrs.

    Jeev125 I would say you take the total and subtract the #day * the down time but saying 1 or 2 am makes it impossible to know unless there is a complete list of hours each day or something.  Furthermore your example doesn't follow your criteria. If there were 8 days and you are shutdown for at least 2am - 4:20am that is >2hrs a day or more than 16hours over 8 days which means the actual hours has to be LESS than 173 hrs and really a max of about 170 hrs but your "actual total" of ~176 hrs is MORE than that which doesn't make sense with the other data/info you gave.  We, or at least I, need more clarification.

      Hi mtarler 

       

      If i take difference between start & finish time which is around ~189 as stated in table (Total), but if exclude non operating hrs from start to finish to be exact i get.

      176:54:50

      i get the actual value when i do calc for each day and sum. 

      what i am trying to achieve to get formula in single cell to dictate the working hrs only in compliance with Operating Hrs fro each day.

        Perhaps like this

        if I understood the logic correctly (can't receive 175 manually as in the grey range).

        In shifts range Finish is the time on next day, i.e. =25/24 fo Sun, etc. Duration=Finish-Start.

        Formula for operating time

        =SUM(INDEX($I$3:$I$9,WEEKDAY(SEQUENCE(INT(C4)-INT(B4)-1,1,INT(B4)+1),1)))+
        INDEX($H$3:$H$9,WEEKDAY($B$4,1))-MOD(B4,1)+
        MOD(C4,1)-INDEX($G$3:$G$9,WEEKDAY($C$4,1))

        assuming your version of Excel supports dynamic arrays.
