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?

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

🙂

The PBIX attached earlier has a "Work Minutes" calculated column that is essentially Work Hours * 60.

That's odd - it's in my post above, but I reattached here in case that helps.
