    Ok...so this appears to work and do what I need:

     

    WeekStart

    = Table.AddColumn(#"WeekStart", each Date.ToText(Date.StartOfWeek([Date], Day.Sunday),"MM/dd/yyyy"))

     

    WeekStart_WeekEnd

    = Table.AddColumn(#"WeekStart_WeekEnd", each Date.ToText(Date.StartOfWeek([Date], Day.Sunday),"MM/dd/yyyy") & "-" & Date.ToText(Date.EndOfWeek([Date], Day.Sunday),"MM/dd/yyyy"))

     

     

     

    I'll leave this here so the next person trying this can hopefully find it and not bang their head for a full day.


    I appreciate all the help.

Hi

 

The below Dax will help to get the week start date. I am assuming that Sunday is your week start date.

 

WeekStartDate = Sheet2[Date]-  WEEKDAY(Sheet2[Date],1)+1  // Sunday as Week start date

WeekStartDate = Sheet2[Date]-  WEEKDAY(Sheet2[Date],2)+1 // Monday as Week start date

 

 

 

 

 

Hope this is what you are looking for.

Can you please help me understand how to use your DAX example?  Is it for a column or Table or Measure?   Is Sheet2 the name of the table?  and [Date] the name of the Date field in the Table?  I am unable to figure out how to get it to work.
