Count Working Days Excluding Weekend and Holidays

[PaulMac]

Hello,

I would like help to produce a column that counts the number of working days between the Date Received column and the Date Acknowledged column that excludes dates that fall on weekends and UK holidays.

I have tried following some examples for historical Power BI forum posts but all these seem to equate to an error.

So, I have produced this sample file with the aim that this will help to provide a workable solution.

Many thanks in advance for your assistance.

Sure. I added this measure as another value in the table you provided:

Working Days = 
COUNTROWS( 
    FILTER(
        ALL(DateDimension), 
        DateDimension[Day of Week] <> 5 && DateDimension[Day of Week] <> 6 && 
        DateDimension[Is Public Holiday?] = "No" && 
        DateDimension[Date] < SELECTEDVALUE(Data[Date Acknowledged]) && 
        DateDimension[Date] >= SELECTEDVALUE(Data[Date Received]) 
    ) 
)

I wasn't sure whether to count the day it was acknowledged or the day it was received in the count, so I just picked one.  For example, if an item was acknowledged and then received on the next day, should that be 1 (since one day has passed) or 2 (there have been 2 calendar days involved)?  If it was acknowledged on Friday and recieved on Sunday, should that be 1(counting Friday) or 0 (since no business days have passed since acknowledgement)?  Change the less than/greater than or equal to signs accordingly.

@CmcmahanYou! Are! A! Star!

Now, is there a way I can tweak your DAX measure to do the samething but as a custom column in Power Query?

Many thanks

You can create calculated columns with DAX, no need to involve Power Query.  https://docs.microsoft.com/en-us/power-bi/desktop-tutorial-create-calculated-columns

All you should need to do is to replace SELECTEDVALUE in the above query with EARLIER, due to the different context.

@PaulMac you can also try following measure

Days Count =
VAR __dateTable =
    CALENDAR ( MAX ( Data[Date Received] ), MAX ( Data[Date Acknowledged] ) )
VAR __table =
    INTERSECT (
        __dateTable,
        CALCULATETABLE (
            VALUES ( DateDimension[Date] ),
            ALL ( DateDimension ),
            DateDimension[Is Public Holiday?] = "No",
            DateDimension[Day of Week] <= 4
        )
    )
RETURN
    COUNTROWS ( __table )
