The superstition surrounding Friday the 13th, known as paraskevidekatriaphobia, blends fear of the number 13 with the day Friday.
Origins are debated but often traced to Norse mythology, where Loki's disruption at a Valhalla banquet led to a tragic event. Biblical accounts link Fridays to misfortune, such as Adam and Eve's sin.
This fear was popularized by cultural references like the "Friday the 13th" film and Dan Brown's The Da Vinci Code. Historically, both Friday and 13 were considered symbols of fortune, but modern figures like Taylor Swift are reshaping these views.
