weeknumber function in vba(excel) doesn't work
 

How to get a proper weeknum function in vba working?
I'm familiar with the weeknum function in the ordinary worksheet, but in vba
it's a different story.
Has anyone suggestions how to generate the weeknumber by the means of a
function in vba?

Many thanks in advance.

Use the date part function

DatePart(Interval, Date

DatePart("ww",date) will produce the week number

To mimic the Excel worksheet function WEEKNUM, you may use this UDF:

===========================
Function VBWeeknum(dt As Date, _
Optional FirstDayOfWeek As Integer = 1)

'VB Replacement for WEEKNUM worksheet function

Select Case FirstDayOfWeek
Case 1 To 2
VBWeeknum = DatePart("ww", dt, FirstDayOfWeek, vbFirstJan1)
Case Else
VBWeeknum = CVErr(xlErrNum)
End Select
End Function
=================================

To generate a weeknumber in accordance with ISO standards, you may use this
UDF:

=========================================
Function ISOWeeknum(d1 As Date) As Integer
' Daniel Maher
Dim d2 As Long
d2 = DateSerial(Year(d1 - Weekday(d1 - 1) + 4), 1, 3)
ISOWeeknum = Int((d1 - d2 + Weekday(d2) + 5) / 7)
End Function
=============================
