Friday the 13th: History, Myths, and Superstitions Behind the Unlucky Day

Friday the 13th is a notoriously unlucky day with deep roots in history, religion and mythology. This superstition, which combines the fear of the number 13 with the importance of Friday, has influenced culture around the world, influencing behaviour and even the economy.

In many Western cultures, Friday the 13th is widely viewed as an unlucky day, with roots deep in history, religion and mythology. This superstition combines people’s fear of the number 13, which is often associated with bad luck, with Friday, which is historically associated with misfortune.

Historical and mythological origins

  1. Biblical Association: Christianity is one of the most important sources of this superstition, as people feared the vengeful wrath of God. During the Last Supper, Jesus had dinner with his twelve disciples, including Judas Iscariot, who was singled out to betray him. The dinner was held on Maundy Thursday, with thirteen people in attendance, and the next day, which was Friday, Jesus was crucified, so Friday became associated with adversity.
  2. Norse Mythology: In Norse mythology, numbers play an important role. One example is the Feast of Thor in Valhalla, which was attended by 12 gods. Loki, the god of mischief, arrived as the thirteenth guest and killed Balder, who represented light and joy among the gods. This myth reinforced the stigma surrounding the number 13.
  3. The Knights Templar: Another reason why Friday the 13th is considered unlucky comes from the arrest of the Knights Templar on October 13, 1307. King Philip IV of France ordered the capture and execution of many Knights Templar, making this day a day of bad luck.

Cultural influences and superstitions

Cultural influences: This superstition is reinforced by various cultural products such as literature and movies. In the United States, TW Lawson awakened this idea in his 1907 novel Friday the 13thIt tells the story of a stockbroker who exploits this superstitious date to create a financial panic.

Paraskevidekatriaphobia: The fear of Friday the 13th has a new name these days: paraskevidekatriaphobia. “Paraskevi” means “Friday” in Greek, and “triskaidekaphobia” refers to the fear of the number 13.

Economic and social impacts: While there is no scientific explanation to support the idea that Friday the 13th is unlucky, it can still have negative consequences. Some people avoid traveling, making major purchases, and even getting married on this day, which has both social and economic impacts. For example, it is estimated that the U.S. economy loses $800 million every Friday the 13th due to people’s avoidance behavior.

Variation of Faith

Interestingly, in some cultures, Friday the 13th is considered unlucky, but in others it is not. In countries like Spain and Latin America, Tuesday the 13th is considered unlucky, while in Italy, the number 17 (not 13) represents bad luck.

Superstitions surrounding Friday the 13th are a complex interplay of historical events, religious beliefs, and cultural narratives. While many view the day with skepticism or humor, for some it remains a source of anxiety and caution, illustrating the enduring power of superstition in shaping human behavior and social norms.

Despite its historical and mythological origins, Friday the 13th continues to impact people’s lives today. From cultural lore to economic consequences, superstition remains a powerful example of how ancient beliefs can influence modern behaviors and social norms.
