    Here is the Power Query code, same logic as the DAX code and the DAX is prettier...

     

    = Table.AddColumn(#"Changed Type", "Custom", each let
  Year = Date.Year(DateTime.Date([Date])),
  Month = Date.Month(DateTime.Date([Date])),
  Day = Date.Day(DateTime.Date([Date]))
in
 if (Day >= 26) and (Month = 12) then #date(Year+1,1,26) else if (Day >= 26) then #date(Year,Month+1,26) else #date(Year,Month,26))

Try this:

 

Column = 
    VAR __Year = YEAR([Date])
    VAR __Month = MONTH([Date])
    VAR __Day = DAY([Date])
RETURN
    SWITCH(TRUE(),
        __Day>=26 && __Month=12,DATE(__Year+1,1,26),
        __Day>=26,DATE(__Year,__Month+1,26),
        DATE(__Year,__Month,26)
    )

Thank you for this,

Is this added as a Custom Column? if so I am getting a "Token Eof expected" error

when I select show error, it highlights __Year

    Yes and I don't get that, attached the PBIX. I did add some spaces between things. I have seen that internationally sometimes having numbers butted up against commas causes problems. If it isn't that, not sure. Seems to work for me.

      Hi Greg_Deckler 

       

      Is this for Power BI or Power Query - (or both)

      as you dropped in a pbix file

      I need this to be added to PowerQuery (get and transform in Excel)

      Maybe the two are synonymouos but as written it ios not recognised by PowerQuery in Excel as a Custom Column
