seasonal randomness

My sister gave me an advent calendar today, which in itself wouldn't be weird. But you know how those things usually are winter or x-mas themed? Well this one has some kind of vaguely Arabic/1001 Nights theme (crappy photo, about 40K), and in addition to the chocolate (hmm, Lindt chocolates...) you get some kind of Arabian proverb behind every door. I have to admit that I don't quite get it, why produce an advent calendar that has nothing to do with Christmas or any of the other usual seasonal trappings? And why Arabian proverbs? I mean, it's an advent calendar. Actually the one my sister has is even stranger in that it doesn't go until the 24th but has doors until New Year. Huh. Yay for increasing secularization, I guess. You can now have advent calendars without them being advent calendars in that they count to Christmas. And incidentally also have more chocolate. :)
