    Eagles83,

    Firstly, import your Federal Holiday sheet and data table to Power BI Desktop.

    Secondly, create a calendar table using calendar() function, create relationship between data  table and calendar table using date field, and create relationship between Federal Holiday table and calendar table using date field, here is an example for you.


    Thirdly, create the following calculated columns in the calendar table.

    WeekDay = WEEKDAY('Calendar'[Date])
    Holiday = RELATED('Federal Holiday'[Holiday])
    If work day = IF(OR('Calendar'[WeekDay]=1,'Calendar'[WeekDay]=7),0,IF(ISBLANK('Calendar'[Holiday]),1,0))
    Rank = RANKX(FILTER('Calendar','Calendar'[If work day]=1),'Calendar'[Date],,ASC)
    Add 3 businss days = LOOKUPVALUE('Calendar'[Date],'Calendar'[If work day],1,'Calendar'[Rank],'Calendar'[Rank]+3)


    At last, create a calculated column using the following DAX in your data table.

    Column = RELATED('Calendar'[Add 3 businss days])

I get an error at Step 3 saying Expression.Error: The name 'WEEKDAY' wasn't recognized. Make sure it's spelled correctly. 

 

Is WeekDay a dax formula or do I need to add a WeekDay table?
