I pasted your code (slightly adapted to the german language notation) in a tiddler and it works. Thank you very much!

I try to update my existing teaching materials from [TWc] to [TW5] for my german speaking pupil. Is it possible to set the days of week and the months to german language? @Eric Shulman: Are you planning to adapt your sophisticated plugins, which you provide at tiddlytools.com to the new TW5? (I love them since years ago when I started to make teaching materials because of their high quality, their further development and the very well documentation.)
