strftime %W (week==0!??)

I get week = 0 right now, why it's week = 1 now!

$this_week = strftime("%W");

I also tried setting setlocale to swedish, but to no help at all!

setlocale(LC_ALL, "swedish");

I run this on a WinNT 4 machine.
PHP v4.06

Any ideas?

Weeknumbers are only a definition. You call it week '1', the rest of the world call's it week '0'.

Readthe manual, you can also use %V to get the ISO standard week, wich does start at 1.

How could I miss it... but anyway %V didn't work on our NT server with PHP v4.06 it returned "" Why??

It did work on our external webserver running Linux apache!

Any workaround??

Silly question: can't you just take the %W number and add one? :-)

Nope, it's not that easy then I would get weeks like 54 sometimes and the first week of the year to start at 2 some years.

But I think I made it now... I'll post the solution when I know it works.
