Calculate number of hours between 2 dates excluding Weekends

[Vivek26]

I have a specific scenario where I need to calculate the number of hours between 2 dates excluding Weekends.

we get orders that move through different stages and we want to calculate how much time each stage is taking on an average.

For example , for an order the step 1 completed on  30th Dec' 2022 at 11 PM 

while the step 2nd completed on  2nd Jan 2022 at 8 AM.

The time taken for step 2 should be shown as 9 hours ( Excluding Saturday and Sunday ) and not 57 hours.

This should be accounted for while calculating all averages.

I really appreciate the help here

Hi @Vivek26 ,

Assuming that the dates of all steps are workdays, try this:

Hours = 
VAR _time_1 =
    CALCULATE (
        MAX ( 'Table'[Status Date] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Order NO] = EARLIER ( 'Table'[Order NO] )
                && 'Table'[Step] < EARLIER ( 'Table'[Step] )
        )
    )
VAR _hours =
    IF (
        ISBLANK ( _time_1 ),
        0,
        DIVIDE ( DATEDIFF ( _time_1, 'Table'[Status Date], SECOND ), 3600 )
            - MAX (
                DATEDIFF ( _time_1, 'Table'[Status Date], DAY ) + 1
                    - NETWORKDAYS ( _time_1, 'Table'[Status Date] ),
                0
            ) * 24
    )
RETURN
    _hours

hi @Vivek26  have you tried to revert the Step values (rows) to a column? this will provide you with the opportuinity to create a measure or a calculated field with a Date Difference between steps, according to your needs.
