13

...is the smallest number with eight letters in its name spelled out in English. It's a prime number and an emirp (a prime that is another prime in reverse). It's a musical, a film, a song, and an album. It's bad luck, good luck, and the number of stripes on the American flag.

And December 13 is Saint Lucia's Day in Sweden. Like many of the Swedish traditions, especially around Christmas, it sounds awfully religious... But fear not; just like the rest of our holidays it's just another excuse to get drunk (lussevaka) and indulge in sweet treats.
