Why do we love this unlucky date on the calendar?
Haunters lean into the unsettling and macabre: things other folks would run from. And Friday the 13th is the calendar embodiment of fear. For superstitious individuals, it represents a lack of control and impending misfortune. For haunt enthusiasts and thrill-seekers, the fear is a calculated, intentional trigger for adrenaline, euphoria, and mental reset. Depending on your mindset, it’s either the unluckiest or most fun date on the calendar.
Except that this year, it’s not just one day: we get three Friday the 13ths in 2026. That’s the maximum we can have in any one year. To celebrate, we’re sharing our 13 favorite facts about this often misunderstood holiday.
1. Some People Just Fear the Number Itself
The clinical term for the irrational fear of Friday the 13th is paraskevidekatriaphobia (derived from the Greek Paraskevi for Friday, dekatreis for thirteen, and phobos for fear). It is also known as friggatriskaidekaphobia, incorporating Frigg, the Norse goddess associated with Friday. Say that three times fast.
Fear of the number 13 itself is triskaidekaphobia. In numerology and ancient cultures, 12 represented completeness (12 months, 12 signs of the zodiac, 12 Olympian gods, 12 tribes of Israel), making 13 feel inherently unbalanced and unsettling.
2. It All Started with the Valhalla Dinner Party Disaster
In Norse mythology, 12 gods gathered for a peaceful banquet in Valhalla. The trickster god Loki crashed uninvited as the 13th guest and tricked Höðr (the blind god of darkness) into fatally shooting Baldr, the beloved god of joy and light, with a mistletoe arrow. This established the folklore omen that having 13 dinner guests brings disaster.
3. The Superstition Also Has Origins in Christian History
Christian tradition linked the two elements: Judas Iscariot was believed to be the 13th guest seated at the Last Supper, and Jesus was crucified on Good Friday. In medieval Europe, Friday was also historically known as “Hangman’s Day” because public executions were frequently scheduled on Fridays.
4. The Knights Templar Downfall
On Friday, October 13, 1307, King Philip IV of France launched a coordinated raid to arrest hundreds of Knights Templar across France on fabricated charges of heresy, sorcery, and treason. Many were tortured and burned at the stake, cementing a dark association between the date and sudden betrayal.
5. It Inspired a Macabre Supper Club
Counterculture embraced Friday the 13th in the late 19th century, when Civil War veteran Captain William Fowler founded The Thirteen Club in New York City specifically to ridicule superstitious dread. Members came dressed in black suits, neckties, and top hats, and would make a point of walking under a ladder before sitting down to dinner.
Five U.S. presidents (Chester A. Arthur, Grover Cleveland, Benjamin Harrison, William McKinley, and Theodore Roosevelt) were honorary members. The group first convened at 8:13 PM on Friday, January 13, 1882. Members dined in tables of 13, tossed spilled salt over the wrong shoulder, and opened umbrellas indoors.
6. It’s Actually More Frequent Than Other Days
Under the 400-year cycle of the Gregorian calendar, the 13th of the month falls on a Friday more often than any other day of the week (688 times per 400-year cycle, compared to 684 for Thursday and Saturday).
Every calendar year has at least one Friday the 13th and can have up to three (any month that begins on a Sunday will contain a Friday the 13th).
7. Before the Movie, There was the Book
Before the movies, American financier Thomas W. Lawson published the 1907 novel Friday, the Thirteenth, depicting a ruthless Wall Street broker who exploits the superstitious public to orchestrate a market crash on that exact day.
8. The Famous Hockey Mask Solidified Its Pop Culture Stardom
The 1980 film Friday the 13th permanently cemented the date into horror pop culture. When Sean S. Cunningham directed the original 1980 Friday the 13th, the titular killer wasn’t Jason Voorhees wielding a machete behind a hockey mask…it was his mother, Pamela Voorhees. Jason didn’t adopt his signature hockey mask until Friday the 13th Part III (1982) after taking it from victim Donnie.
9. You Might Get a Deal Today
Rather than avoiding the day, alternative and horror subcultures embraced it as a holiday. Tattoo parlors across North America popularized “$13 flash tattoo specials” (often with a mandatory $7 tip for good luck), turning a day of bad omens into a celebration of macabre art.
10. In Some Countries, Tuesday is Unlucky
In Greece and Spanish-speaking countries, Tuesday the 13th (Martes 13) is the dreaded date rather than Friday. Tuesday is associated with Ares/Mars (the god of war), giving rise to the proverb: “En martes, ni te cases, ni te embarques” (“On Tuesday, neither marry nor embark on a journey”).
11. In Italy, it’s Friday the 17th
In Italy, Friday the 17th is feared instead of the 13th. In Roman numerals, 17 is XVII, an anagram of VIXI…which translates in Latin to “I have lived” (implying “my life is over / I am dead”).
12. The Holiday Has a More Recent History with Haunted Attractions
They might seem like a natural fit, but haunted attractions really didn’t embrace Friday the 13th until recently. Between 2011 and 2015, off-season haunts exploded into standard industry practice. Alongside “My Bloody Valentine”, “A Saint Patrick’s Day Massacre”, and Krampus/Christmas haunts, every off-season Friday the 13th became a staple calendar anchor across the United States.
13. 2026 Has the Maximum Unlucky days Possible
According to the Old Farmer’s Almanac, there can be as few as one and as many as three Fridays the 13th in any given year. And we only get three every 14 years! Whether you consider it lucky or unlucky, 2026 is one of those years with triple the Friday the 13ths:
- February 13
- March 13
- November 13
Final Thoughts
While the superstitious world stays home, avoids signing contracts, or dodges black cats, haunters treat Friday the 13th like an unofficial holiday.
Remember, whenever a month starts on a Sunday, a Friday the 13th is guaranteed…and we watch with anticipation as haunters rally their actors, fire up their fog machines, and open their doors for one night only.
