Well, I didn't notice, but perhaps because its correct in German, at least kind of: we write it "Kalender". There is however the word "kalendarisch" which means, um, calendrical... if there is such thing in english at all. It means "by calendar", "according to calendar",
Jeez, what's that, a grammar nazi ... oh. Never mind.
:-)
But it's right, after all. And it could be that the worst part is, nobody noticed.

I don't think we have such a word--but maybe we should.
