How Friday The 13th Works

In this episode of How It Works, we peel back the layers of superstition and history surrounding the world’s most infamous day: Friday the 13th. We journey through the origins of "paraskevidekatriaphobia," exploring how the convergence of a supposedly unlucky number and a day steeped in religious and cultural folklore created a persistent modern-day phobia. From the ancient numerical significance of the number 13 to the historical accounts of knights and biblical lore, we examine why this date continues to trigger anxiety and shape behavior across the globe. Join us as we separate historical fact from cultural fiction to understand the psychological forces that keep this eerie calendar anomaly at the forefront of the collective imagination.
