History Schmistory: Friday the 13th Edition.

Not a good day for lucky people. But what’s the origin? Well, to be honest, no one knows. Could be one of three things:
1. Norse mythology about some convoluted council of thirteen whatevers and the goddess Frigga (from whom we get the name Friday).
2. (made popular in The DaVinci Code) Friday, October 13, 1307, the date King Philip IV of France ordered the arrest of the Knights Templar–unlikely, though, since few people recognized Friday the 13th superstitions before the 20th century
3. Publication of a popular 1907 novel called Friday, the 13th. This is actually most likely, since the first references to this day as unlucky date from this time.
Either way, don’t break any mirrors or hang out with any black cats.
