create a dynamic column header based on measures

[Jeanxyz]

I have created a timesheet matrix table as below. the current column field is Intl week number (e.g., 13, 14,15...). I need to populate the start date of each week into the column header, something like "week14 - 4/4/2022". Is there a way to populate this value to the column header. 

It's easy to populate this data in a table, but I have to use a matrix table here, hence there is an issue.

Thank you! Your solution worked. I had forgotten to accepted it as a solution though.

Week Start Date/Wk No = CONCATENATE(Data[Date] – WEEKDAY(Data[Date],2) + 1,Intl week number)
//try this one

The thing is I can't drag a measure into the column field. I have create a tooltip page to show weekstart data. Maybe someone has a better solution.

Hi @Jeanxyz ,

Please create a calculated column in the calendar table.

Week_Date = 
VAR _weeknum =
    WEEKNUM ( 'Calendar'[Date], 2 )
VAR _firstdate =
    CALCULATE (
        MIN ( 'Calendar'[Date] ),
        FILTER ( ALL ( 'Calendar'[Date] ), WEEKNUM ( 'Calendar'[Date], 2 ) = _weeknum )
    )
VAR _result = "Week" & _weeknum & "-" & _firstdate
RETURN
    _result

Then use this column as a field of the matrix column.
