History of Friday the 13th

Friday The 13th

If you’re reading this article to learn the history of Friday the 13th, you’re in luck.

Or perhaps bad luck.

No one knows, with any certainty, when it began or why it’s to be feared. However, there are lots of entertaining speculative theories about the topic.



What is the Fear of Friday the 13th?

  • Paraskevidekatriaphobia — is the name of the superstition. The word is constructed from the Greek words Paraskeví (Παρασκευή) meaning “Friday”, and dekatreís (δεκατρείς) meaning “thirteen.”
  • Friggatriskaidekaphobia — is the fear of Friday the 13th. The word is made of both Norse and Greek roots: Frigg or Frigga, the name of the wife of the Norse god Odin. Friday gets its name from Frigg. Triskadeka is “thirteen” in Greek (literally: “three” “and” “ten”), and phobia means “fear.”

12 is completeness, 13 is useless

Twelve is considered in many cultures as complete. Mathematically it can be divided into half, thirds, and quarters. You can’t do that neatly with Ten.


  • 12 Days of Christmas
  • 12 days of Christmas
  • 12 hours in a day
  • 12 months
  • 12 Zodiac signs
  • 12 gods of Olympus and Norse mythology

Thirteen is a dubious number, and Friday has gotten a bad rap. Add them together, and you get Friday the 13th.
