Happy Friday the 13th!

To some this day is one of pure dread and horror. Yet others think it just a day filled with bad luck waiting to rain down from bleak skies. Still, others find it a day of celebration — a day just shy of Halloween in order of evil magnitude.

But where did this myth come from? Why is Friday the 13th so unlucky? Was it the birthday of Satan? Did some atrocity occur on this day to lend it some hateful credence? You’ll be surprised by the answer.

According to the Wikipedia entry (so it must be true — wink, wink), the following possibilities exist for the reasoning behind the madness:

  • In numerology, the number twelve is considered the number of completeness, as reflected in the twelve months of the year, twelve hours of the clock, twelve gods of Olympus, twelve tribes of Israeltwelve Apostles of Jesusthe 12 successors of Muhammad in Shia Islam, etc., whereas the number thirteen was considered irregular, transgressing this completeness. There is also a superstition, thought by some to derive from the Last Supper or a Norse myth, that having thirteen people seated at a table will result in the death of one of the diners.
  • Friday has been considered an unlucky day at least since the 14th century’s The Canterbury Tales,[4] and many other professions have regarded Friday as an unlucky day to undertake journeys, begin new projects or deploy releases in production. Black Fridayhas been associated with stock market crashes and other disasters since the 1800s.[3][5] It has also been suggested that Friday has been considered an unlucky day because, according to Christian scripture and tradition, Jesus was crucified on a Friday.[6]
  • One author, noting that references are all but nonexistent before 1907 but frequently seen thereafter, has argued that its popularity derives from the publication that year of Thomas W. Lawson‘s popular novel Friday, the Thirteenth,[7] in which an unscrupulous broker takes advantage of the superstition to create a Wall Street panic on a Friday the 13th.[1] Records of the superstition are rarely found before the 20th century, when it became extremely common.
