VBA Convert date to week number

Question

In VBA I want to convert a date as 03/11/2017(DD/MM/YYYY) into the week number for that date.

Until now I have the following code:

   \'geting the d         


        

Answer 1

So, this is my final and working perfectly version

Public Function IsoWeekNumber(d As Date) As String

    Dim kwtemp As String

    kwtemp = DatePart("ww", d, vbMonday, vbFirstFourDays)

    If Len(kwtemp) = 1 Then kwtemp = "0" & kwtemp

    IsoWeekNumber = kwtemp

End Function

If Application.International(xlMDY) = True Then

HeadlineTemp = Mid(VRHeadline, InStr(VRHeadline, "[") + 1, 10)
HeadlineTemp = Replace(HeadlineTemp, ".", "/")
HeadlineTemp = Mid(HeadlineTemp, 4, 3) & Left(HeadlineTemp, 2) & Right(HeadlineTemp, 5)
VRFirstKW = CDate(HeadlineTemp)
HeadlineTempEndKW = Mid(VRHeadline, InStr(VRHeadline, "]") - 10, 10)
HeadlineTempEndKW = Replace(HeadlineTempEndKW, ".", "/")
HeadlineTempEndKW = Mid(HeadlineTempEndKW, 4, 3) & Left(HeadlineTempEndKW, 2) & Right(HeadlineTempEndKW, 5)
VREndKW = CDate(HeadlineTempEndKW)
VRKW = "KW" & IsoWeekNumber(VRFirstKW) & "-" & IsoWeekNumber(VREndKW) & "/" & Year(VREndKW)

    Else 'don't switch position of the month with days

    HeadlineTemp = Mid(VRHeadline, InStr(VRHeadline, "[") + 1, 10)
    HeadlineTemp = Replace(HeadlineTemp, ".", "/")
    VRFirstKW = CDate(HeadlineTemp)
    HeadlineTempEndKW = Mid(VRHeadline, InStr(VRHeadline, "]") - 10, 10)
    HeadlineTempEndKW = Replace(HeadlineTempEndKW, ".", "/")
    VREndKW = CDate(HeadlineTempEndKW)
    VRKW = "KW" & IsoWeekNumber(VRFirstKW) & "-" & IsoWeekNumber(VREndKW) & "/" & Year(VREndKW)
