Hi @jayceeb,

I create a table as you mentioned.

Then I create two calculated columns and here are the DAX codes.

WeekRange =

VAR StartOfWeek =

    'Table'[Date] - WEEKDAY ( 'Table'[Date], 2 ) + 1

VAR EndOfWeek = StartOfWeek + 6

RETURN

    FORMAT ( StartOfWeek, "MMM d" ) & " - "

        & FORMAT ( EndOfWeek, "MMM d" )

WeekNumber =

"week "

    & WEEKNUM ( 'Table'[Date], 2 ) - WEEKNUM ( STARTOFMONTH ( 'Table'[Date] ), 2 ) + 1

Next I think you can create a new table.

WeeklyTrends =

SUMMARIZE(

    'Table',

    'Table'[WeekRange],

    'Table'[WeekNumber],

    "Total", SUM('Table'[Quantity])

)

Hi @jayceeb ,

In Power BI Desktop, if you want to use a DAX statement after selecting a date, you need to strictly follow the Week rule on the calendar to do so. 

WeeklyTotal = 
CALCULATE(
    [TotalQuantity],
    ALLEXCEPT('Table', 'Table'[MonthYear], 'Table'[WeekNumber])
)

@jayceeb , You have create week columns in you table

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],1)+1 //Sunday

Week Start date Monday = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1 //Monday

Week End date = [Week Start date] +6

format and use in other column
