matrin , You can weekrank and week number for that to compare Same week 364 day behind or 52 week behind. Have date table with following columns

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Number = WEEKNUM([Date],2)
Week = if('Date'[Week Number]<10,'Date'[Year]*10 & 'Date'[Week Number],'Date'[Year]&'Date'[Week Number])
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)

This Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))

Last year Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-52))

Week Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-364,DAY))

Hi matrin ,

You can create these calculated columns to calculate each year week total sales:

Week = WEEKNUM('Table'[Date],1)

Total =
CALCULATE (
    SUM ( 'Table'[Sales] ),
    ALLEXCEPT ( 'Table', 'Table'[Week], 'Table'[Date].[Year] )
)

If you want to see the evolution, use a line chart and multi select the slicer with year and month:
