Friday the 13th is a day that has long been considered unlucky. Although the specifics of when this tradition began are uncertain, the superstition likely dates back to a longstanding Christian superstition that because of the seating arrangement at the Last Supper, having 13 guests at a table was a bad omen. The fear of the number 13 is so bad for some that it has been given a name: triskaidekaphobia.
