DID YOU KNOW? THE ORIGINS OF FRIDAY THE 13TH
Long before modern pop culture and horror franchises cemented its eerie reputation, the superstition surrounding Friday the 13th was forged from centuries of overlapping religious anxieties, ancient mythology, and historical events.
Historical records indicate that the fear of the number 13 likely stems from several distinct cultural touchstones. In Norse legend, a disastrous banquet in Valhalla featured 12 gods before the uninvited 13th guest, Loki, orchestrated the death of Balder. In Christianity, Judas Iscariot was famously the 13th guest at the Last Supper. Numerologically, the number 13 also disrupts the perceived completeness of 12, as seen in the months of the year, hours on a clock, and signs of the Zodiac.
Meanwhile, Fridays carried their own heavy historical burdens. Beyond bearing the association with the traditional crucifixion of Jesus on Good Friday, the day was historically designated as “hangman’s day” for public executions in Britain. A pivotal historical convergence occurred on Friday, October 13, 1307, when King Philip IV of France ordered the mass arrest and execution of the Knights Templar.
While these elements were feared separately for centuries, folklorists note that the specific unification of Friday and the number 13 into a single day of bad luck did not emerge widely until the 19th century, later popularized by literature and the 1980 film bearing the date’s name.
Cultural equivalents vary widely around the globe:
- In Spain, Latin America, and Greece, Tuesday the 13th is viewed as deeply unlucky due to associations with Mars, the Roman god of war, and historical traumas like the fall of Constantinople.
- In Italy, the unluckiest date is Friday the 17th, because the Roman numeral XVII rearranges to spell “VIXI,” a phrase meaning “I have lived” typically found on ancient tombstones.
- In East Asia, the number 4 serves a similar role to 13 because its pronunciation, “shi”, closely resembles the word for “death.”
