Exclude weekends and holidays from calculated column result

[stackedcreative]

I've read other posts that are slightly different than my needs.

SvcDone-Join = [ServiceDone]-[JoinDate] 

The result is number of days it took to Deploy a PC. 

This number should exclude weekends and U.S. holidays if the SPAN of the 2 dates includes weekends or holidays.  Not just for this year, but for each future year, as well.  

I've seen this: 

Dates =
ADDCOLUMNS (
    CALENDAR ( DATE ( 2019, 1, 1 ), DATE ( 2019, 12, 31 ) ),
    "Day Name", FORMAT ( [Date], "ddd" ),
    "Weekday", IF ( WEEKDAY ( [Date], 2 ) >= 6, 0, 1 )
)

But that's only 2019 instead of all years.  Is there a way to use that formula for any year?  Or is there another calculation?  

TIA

Hello @stackedcreative 

"But that's only 2019 instead of all years.  Is there a way to use that formula for any year?"

You can change the parameters in the date function to include any year(s). 

Dates =
ADDCOLUMNS (
    CALENDAR ( DATE ( 2019, 1, 1 ), DATE ( 2019, 12, 31 ) ),
    "Day Name", FORMAT ( [Date], "ddd" ),
    "Weekday", IF ( WEEKDAY ( [Date], 2 ) >= 6, 0, 1 )
)
TO
Dates =
ADDCOLUMNS (
    CALENDAR ( DATE ( 2019, 1, 1 ), DATE ( 2022, 12, 31 ) ),
    "Day Name", FORMAT ( [Date], "ddd" ),
    "Weekday", IF ( WEEKDAY ( [Date], 2 ) >= 6, 0, 1 )
)

This will create calendar year upto 2022.

Hello All, may I widen the possibilities? How about if there are 4 contact centers in the following countries:
1. Singapore

2. Rome
3. Los Angeles and 
4. Beijing
The questions come up as to which country? which holidays and which time-zone to start the week/end?
Is this even possible? Thank you for your input. Cheers.

Hi  @stackedcreative ,

Try the following steps:

Step1，use the following dax ,to create data table:

Dates = CALENDAR("2019/1/1","2021/12/31")

Step2, import holiday in 2016 and 2017,refer:

Creating A Calendar Table For Holidays In Power BI

https://blog.enterprisedna.co/creating-a-calendar-table-for-holidays-in-power-bi/ 

And import web link :

https://www.calendarpedia.com/holidays/federal-holidays-2019.html

https://www.calendarpedia.com/holidays/federal-holidays-2020.html 

https://www.calendarpedia.com/holidays/federal-holidays-2021.html 

And you will see the below:

Step 3, base on dates,and holiday table ,to create a new table ,use the following dax(when weekend and holiday ,the column return false)

date1 = 
GENERATE (
    CALENDARAUTO (),
    VAR yyyy =
        YEAR ( [Date] )
    VAR mmmm =
        MONTH ( [Date] )
    RETURN
        ROW ("Date1",FORMAT ( [Date], "YYYY-MM-DD" ),
            "Year", yyyy,
            "Month", FORMAT ( [Date], "mmmm" ),
            "Month2", mmmm,
            "Week1", FORMAT ( [Date], "dddd" ),
            "Week2", WEEKDAY ( [Date] ),
            "weekday", NOT WEEKDAY ( [Date] ) IN { 1, 7 } && not [Date] in VALUES('2019'[Date])&& not [Date] in VALUES('2020'[Date])&& not [Date] in VALUES('2021'[Date])
        )
)

You will see the below:

The below due to I without your pbix file,may be you need to do some adjust:

difforder =
VAR day1 =
    CALCULATE (
        COUNTROWS ( 'date1' ),
        DATESBETWEEN ( date1[Date], TableName[JoinDate], TableName[ServiceDone] ),
        date1[weekday] <> TRUE,
        ALL ( TableName)
    )
VAR day2 =
    IF ( day1 = BLANK (), 0, day1 )
VAR day3 =
    DATEDIFF ( TableName[JoinDate], TableName[ServiceDone], Day) - day2
RETURN
    day3

Wish it is helpful for you!

Best Regards

Lucien

@stackedcreative . Work day as measure and column

measure

Work Day = COUNTROWS(FILTER(ADDCOLUMNS(CALENDAR(Min(Table[ServiceDone]),Max(Table[End Date])),"WorkDay", if(WEEKDAY([Date],2) <6,1,0)),[JoinDate] =1))

Column

Work Day = COUNTROWS(FILTER(ADDCOLUMNS(CALENDAR(Table[ServiceDone],Table[End Date]),"WorkDay", if(WEEKDAY([JoinDate],2) <6,1,0)),[WorkDay] =1))

else you need to create a calendar with holiday and use that for date diff
