The Real Story Behind Friday the 13th

Gulf Shores, AL. — (GSN) — Friday the 13th has long held a unique position in Western folklore as a day associated with bad luck, suspense, and superstition. Occurring whenever the 13th day of a calendar month falls on a Friday, this date happens between one and three times each year.
The modern fear of Friday the 13th stems from a confluence of ancient myths, religious traditions, and historical tales surrounding both the number 13 and the day Friday.
- Norse Mythology: One of the earliest tales explaining the unluckiness of 13 involves a banquet in Valhalla attended by 12 Norse gods. The trickster god Loki crashed the gathering as the 13th guest and engineered the murder of Balder, the beloved god of joy, plunging the world into mourning.
- Christian Traditions: In Christian lore, 13 guests were present at the Last Supper (Jesus and his 12 apostles), and Judas Iscariot is often identified as the 13th attendee. The following day, Good Friday, was the day of Jesus’s crucifixion. Additionally, traditional folklore holds that Eve tempted Adam with the forbidden fruit and Cain slew Abel on a Friday.
- The Knights Templar: On Friday, October 13, 1307, King Philip IV of France ordered the sudden mass arrest of the Knights Templar. Many knights were tortured, charged with heresy, and executed. While historians note that Friday the 13th was not explicitly considered unlucky at that exact time, this event significantly enriched the day's dark legend in popular culture.
- 19th and 20th-Century Popularization: Written references joining Friday and the number 13 into a single superstition became common in the 19th century. The fear gained broader media traction with Thomas W. Lawson’s 1907 novel Friday, the Thirteenth, which depicted a stockbroker manipulating the date's superstition to cause market panic. Later, the iconic 1980 horror film Friday the 13th solidified the date’s spooky reputation in modern pop culture.
The anxiety surrounding Friday the 13th is recognized clinically, complete with specific terminology:
- Paraskevidekatriaphobia (or Friggatriskaidekaphobia): Derived from the Greek words for Friday (Paraskevi), thirteen (dekatria), and fear (phobos), or joining the Norse goddess Frigg (for whom Friday is named) with triskaidekaphobia.
- Triskaidekaphobia: The general fear or avoidance of the number 13.
The impact of this fear extends beyond psychological discomfort. Businesses, airlines, and real estate markets often see reduced traffic on Friday the 13th due to superstitious travelers and consumers opting to stay home, leading to estimated losses of hundreds of millions of dollars on these days. Many high-rise hotels and office buildings famously skip naming the 13th floor, jumping directly from 12 to 14.
Historic Events That Occurred on Friday the 13th
While bad events occur every day of the year, several notable historical occurrences coincidentally fell on a Friday the 13th:
- October 13, 1307: King Philip IV of France launched mass raids and arrests targeting the Knights Templar.
- April 13, 1866: The American train robber and outlaw Butch Cassidy was born.

Despite its ominous reputation, there is no scientific or statistical evidence that Friday the 13th carries more risk than any other date on the calendar.
Confirmation Bias: People are far more likely to notice and remember something negative happening if it occurs on Friday the 13th because of cognitive priming, while forgetting the countless mundane or good things that happen on the same day.
Cultural Relativity: Superstitions surrounding dates vary worldwide. In Hispanic cultures and Greece, Tuesday the 13th is traditionally viewed as unlucky, while in Italy, Friday the 17th carries the ominous distinction. In other traditions, 13 is viewed favorably.
Statistical Inevitability: With Friday the 13th occurring 1 to 3 times every year across thousands of calendar years, major global events are bound to fall on this day purely by random chance.
So, there is really no reason to lock yourself away today. Go ahead and enjoy your day—just stay a few feet back from the water's edge as you stroll the beach, keep your eyes firmly on the road as you drive over bridges, and make sure you completely peel the shrimp before eating. A little caution goes a long way, no matter what date is on the calendar.
