 Friday The 13 th

Friday the 13th is widely regarded as an unlucky day in many Western cultures, blending fears of the number 13 (triskaidekaphobia) with the, often, unlucky reputation of Fridays. This superstition, rooted in Christian, historical, and mythological traditions, can lead to anxiety, with 2026 featuring three such dates. 

Christian Traditions: Often linked to the Last Supper, where Judas Iscariot, the 13th guest, betrayed Jesus, who was crucified on a Friday. Other beliefs include Friday being the day Eve ate the forbidden fruit and when Cain murdered Abel.
