    Hi. The easiest way I figure out right now is adding a new custom column with Power Query in the same table that has the Date Column. The code should be like this:

ibarrau, thank you for the suggestion! Your solution triggered the idea to just use the round function directly in Power BI > Modeling > New Column.

 

Week = ROUNDUP( Dates[DayNoOfYear] / 7, 0 )
 
And I get day number of year [DayNoOfYear] from:
 
DayNoOfYear = DATEDIFF ( DATE ( YEAR ( Dates[Date] ), 1, 1 ), Dates[Date], DAY ) + 1
