## 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 ?

@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``````

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.
