Origins of Friday the 13th
The superstition surrounding Friday the 13th has complex roots dating back to mythology, religion, and popular culture. One of the main starting points is Norse mythology, where the number 13 is related to Loki, the god of chaos and mischief. At the Christian Last Supper, the 13th guest was Judas Iscariot, the apostle who betrayed Jesus, contributing to the negative perception of the number 13 in Christian culture.
The Fear of Friday
The fear of Friday itself has its roots in the Christian religion. Jesus was crucified on a Friday, and in the Middle Ages, Fridays were considered unlucky days to carry out any important activity. The combination of the number 13 with Friday fueled superstition and the belief in a cursed day.
