Switch from WEEKNUM to time range

Hello dear community,

I would like to create a new column on my Calendar Table who gives the time range instead of the week num. For example :

For Week number 1 of 2023, ill get a value like "02/01 to 08/01".

ChatGPT tried to give me this solution, who only works for the first year 2023 : 

Range =
VAR FirstDateOfWeek =
    MINX(
        FILTER(
            Calendrier,
            Calendrier[Semaine] = EARLIER(Calendrier[Semaine])
        ),
        Calendrier[Date]
    )
VAR LastDateOfWeek =
    MAXX(
        FILTER(
            Calendrier,
            Calendrier[Semaine] = EARLIER(Calendrier[Semaine])
        ),
        Calendrier[Date]
    )
VAR LastDateOfWeekMinusOne =
    LastDateOfWeek - 1
VAR LastDateOfYear =
    CALCULATE(
        MAX(Calendrier[Date]),
        CALENDRIER[Annee] = MAX(Calendrier[Annee])
    )
RETURN
    "Du " & FORMAT(FirstDateOfWeek, "dd/MM") & " au " &
    IF(
        LastDateOfWeek = LastDateOfYear,
        FORMAT(LastDateOfWeek, "dd/MM"),
        FORMAT(LastDateOfWeekMinusOne, "dd/MM")
    )
 
Does someone here know an elegant way to provide this Range column for every year on a very large calendar ?
 
A great thank you for your reading,

@LZNPM Try:

Range = 
    VAR __WeekNum = [WeekNum]
    VAR __Year = YEAR([Date])
    VAR __Min = MINX(FILTER('Dates', [WeekNum] = __WeekNum && YEAR([Date]) = __Year), [Date])
    VAR __Max = MAXX(FILTER('Dates', [WeekNum] = __WeekNum && YEAR([Date]) = __Year), [Date])
    VAR __Return = FORMAT(__Min, "dd/MM") & " to " & FORMAT(__Max, "dd/MM")
RETURN
    __Return

DAX is easy, CALCULATE makes DAX hard...

Thank you very much Greg ! Your code works very well... until the year switch ! For all weeks in 2023 the correct time range is written, but for the first week of 2024, the value of the new column is "01/01 to 31/12". How can I correct it ? If you have an idea.
