What Happened on Friday the 13th? 13 Facts About the Unlucky Day

Stevie Wonder might have said “superstition ain’t the way,” but those of us that celebrate Friday the 13th can’t be bothered with his advice. Whether you mark with a new tattoo, binge-watch scary movies all night, or spend all day anticipating a spike in unfortunate occurrences, reveling in the spookiness of Friday the 13th can be quite fun. That said, we can’t help but wonder what happened on Friday the 13th to make the day so unlucky (and spooky).

What happened on Friday the 13th

Many believe Friday the 13th superstitions began in the Middle Ages and had to do with the story of Jesus’s last supper and crucifixion. According to the story, 13 people were present, and it took place on the 13th of Nisan Maundy Thursday before his execution on Good Friday. However, since the last supper occurred on a Thursday, this example only reveals the separate reasons why the number 13 and Friday were considered unlucky. In fact, there was no reference to both Friday and the number 13 being unlucky together until the late 19th century.

Despite popping up in the late 19th century, the superstitions surrounding Friday the 13th didn’t take off until 1907 when Thomas W. Lawson’s Friday, the Thirteenth published. That said, the famous novel isn’t the only reason the date became so well-known.

In the 20th century, a new origin was theorized — one that would finally explain why both the day and date are so unlucky. In addition to the story of Jesus’s last summer, many came to believe that the superstition dates back to Friday, October 13, 1307, when Philip IV of France arrested hundreds of the Knights Templar. Since the 20th century, the theory has spread widely and been mentioned in many novels, including Maurice Druon’s The Iron King, Steve Berry’s The Templar Legacy, and Dan Brown’s The Da Vinci Code.t
