how did friday the 13th start

Friday the 13th as an “unlucky” day grew out of several overlapping superstitions about the number 13 and about Fridays, then got supercharged by books, media, and eventually horror movies that turned it into a pop‑culture icon.

Quick Scoop: How did Friday the 13th start?

1. Two older fears colliding

Before anyone worried about a specific date, people in Western cultures already thought both 13 and Friday were bad news.

• The number 12 was seen as “complete” (12 months, 12 zodiac signs, 12 apostles), so 13 felt odd and unstable.

• Some Christian traditions linked 13 at a table with betrayal because Judas is often described as the 13th guest at the Last Supper.

• Friday gained a gloomy reputation in Christian Europe because of beliefs that Jesus was crucified on a Friday (Good Friday), and it became associated with endings, misfortune, or bad omens.

Put together, an “unlucky number” landing on an “unlucky day” created a perfect superstition storm.

2. The medieval Templar story

One of the most famous origin stories points to a real historical crackdown:

• On Friday, October 13, 1307, King Philip IV of France ordered the arrest of the Knights Templar, a powerful religious‑military order, with backing from Pope Clement V.

• Many Templars were imprisoned, tortured, or executed, which later storytellers framed as a cursed or doomed Friday the 13th.

Historians debate how much people at the time truly linked that date to a broader superstition, but the story is now often quoted as a “classic” origin myth.

3. Religious and mythic layers

Other threads helped build the vibe around 13 and Friday before the modern meme took off:

• Christian storytelling: 13 guests at the Last Supper and the crucifixion on Friday reinforced the sense that combining “13” and “Friday” meant betrayal and suffering.

• Norse myth: some writers cite a story where Loki becomes the 13th guest at a feast in Valhalla, leading to the death of Balder, a beloved god, turning 13 into a symbol of chaos and tragedy.

These stories aren’t all from the same era or culture, but together they gave centuries of narrative “evidence” that 13, and sometimes Friday, brought trouble.

4. When the date itself became “a thing”

The specific idea that “Friday the 13th” is bad luck is surprisingly modern.

• By the late 1800s in the U.S., groups like the Thirteen Club in New York met with 13 people, on the 13th, under ladders, and more, specifically to mock superstitions about 13.

• Around the late 19th and early 20th centuries, references to Friday the 13th as an unlucky date start showing up more clearly in print.

• A big push came from Thomas W. Lawson’s 1907 novel “Friday, the Thirteenth,” about a stockbroker who uses the date’s bad‑luck reputation to crash the market, helping cement the phrase in popular imagination.

From that point, the date itself—not just 13 or Friday separately—became a recognizable superstition.

5. Pop culture supercharges it

In the late 20th century, entertainment turned Friday the 13th from a superstition into a global horror brand.

• The 1980 slasher film “Friday the 13th” (and its many sequels and spin‑offs) made the date synonymous with masked killers, jump scares, and campfire horror.

• Media coverage, lists of “bad things that happened on Friday the 13th,” and repeated horror reboots keep the date in the news cycle whenever it pops up on the calendar.

Now, for many people, the date feels like a mini horror holiday or meme day more than a deeply held belief.

6. Modern impact and “latest vibe”

Even today, Friday the 13th has real‑world effects.

• Surveys suggest millions of Americans say they feel uneasy or change behavior (avoiding flights, big purchases, or major events) on Friday the 13th.

• Some analysts and writers have claimed that reduced travel and spending on that date can cost the economy significant sums, although estimates vary and are debated.

• Online, every time the date rolls around (including in the 2020s), social feeds fill with jokes, horror references, and news outlets revisiting the superstition’s history, so it stays a recurring trending topic.

So, how did Friday the 13th start?
It didn’t begin with one single event. It grew slowly: old fears of 13 and Friday, dramatic stories like the Templar arrests, religious and mythic symbolism, then modern novels, news, and horror films that turned it into the “unluckiest” day on the calendar.
