i have the following data 

 

 

start date end datestatus
2023-07-02 6:01:002023-07-04 15:10:11confirmed

 

1- i want to calculate the time difference in hours only if it is between 8:00:00 and 17:10:00 so the example upove should be 25 hours

 

2- and i want the same thing but in minutes 

please help me and thank you  

 

  • Hi mina97 

    I have attached a PBIX with suggested calculated colums in DAX for Work Hours and Work Minutes.

    The code is a bit long-winded in order to capture the required logic.

    I assumed:

    • Weekends/holidays do not need to be excluded. If you do, you would need to adjust and use NETWORKDAYS.
    • You want to round down to the nearest integer.

    Here is the expression for Work Hours (Work Minutes is similar):

    Work Hours = 
    -- Working Start and End time 
    VAR WorkTimeStart = TIME ( 08, 00, 00 )
    VAR WorkTimeEnd = TIME ( 17, 10, 10 )
    VAR WorkingHours = ( WorkTimeEnd - WorkTimeStart )
    
    -- Start and End date/time on current row
    VAR StartingDateTime = Data[start date]
    VAR EndingDateTime   = Data[end date]
    
    VAR StartingTime= StartingDateTime - TRUNC ( StartingDateTime )
    VAR StartingDate = StartingDateTime - StartingTime
    
    VAR EndingTime = EndingDateTime - TRUNC ( EndingDateTime )
    VAR EndingDate = EndingDateTime - EndingTime
    
    -- Adjust start/end times to fall within working hours.
    VAR StartingTimeEffective =
        MIN (
            MAX ( StartingTime, WorkTimeStart ),
            WorkTimeEnd
        )
    VAR EndingTimeEffective =
        MAX (
            MIN ( EndingTime, WorkTimeEnd ),
            WorkTimeStart
        )
    -- Adjust for hours not worked on StartingDate
    --   StartingTimeOffset will always be <= 0
    VAR StartingTimeOffset =
        WorkTimeStart - StartingTimeEffective
    -- Adjust for hours not worked on EndingDate
    --   EndingTimeOffset will always be <= 0
    VAR EndingTimeOffset =
        EndingTimeEffective - WorkTimeEnd
    VAR DayCount =
        EndingDate - StartingDate + 1
    VAR TotalTimeInDays =
        DayCount * WorkingHours + StartingTimeOffset + EndingTimeOffset
    VAR TotalTimeInHours =
        TotalTimeInDays * 24
    VAR TotalTimeInHoursRounded =
        ROUNDDOWN ( TotalTimeInHours, 0 )
    RETURN
        TotalTimeInHoursRounded

    This is a good article on a similar but different calculation:

    Does this work for you?

     

    Regards

  • Hi mina97 

    Glad it helped.

    The expression does just count working hours.

    The variable TotalTimeInDays does just include working hours, with an adjustment for the start/end times.

     

    But let me know if you have a specific example where it is not working.

    Regards
