When discussing Friday the 13th, many believe the Bible plays a large part in the date being seen as an unlucky. In the New Testament, there were thirteen guests at the Last Supper: Jesus and his 12 apostles. The Last Supper was held on what is now called Maundy Thursday (Holy Thursday).

Spoiler alert: One of the 13 people in attendance, Judas Iscariot, betrayed Jesus who was crucified the next day, a Friday. To commemorate the death of Jesus, the Catholic Canon (law) states that followers should avoid eating meat every Friday of the year as a sign of penance for the sacrifice that Jesus gave of Himself.

Norse Mythology also tells of a similar story that helps explain the distrust associated with the the number 13. According to the myth, 12 gods were at a dinner party in Valhalla when a 13 guest, Loki, arrived uninvited. Known as the god of mischief, Loki plotted for the blind goddess of darkness, Hoder, to kill the god of joy and gladness — Balder the Beautiful. Balder’s death made the whole world go dark in mourning and has long since been the reason the number 13 is considered ominous.
