Much better now, My dutch dates look fine in dynamic pages.
But one little problem: I made a custum template for my daily archives. If I click on a date in the calendar I get the daily archive page of that specific date, static that is.

If I build these archives dynamically, no matter what day I click I allways get the last daily archive in my weblog, 26 december 2004 that is. Even from an october page.
