Today is Friday the 13th! Are you scared? Maybe you should be?

According to folklorists, there is no written evidence for a "Friday the 13th" superstition before the 19th century.[1][2][3] The earliest known documented reference in English occurs in Henry Sutherland Edwards' 1869 biography of Gioachino Rossini, who died on a Friday 13th. Several theories have been proposed about the origin of the Friday the 13th superstition.

One theory states that it is a modern amalgamation of two older superstitions: that thirteen is an unlucky number and that Friday is an unlucky day.
