14 Terrible Things That Have Happened on Friday the 13th

Friday the 13th is so famously unlucky that there’s even a phobia dedicated to it: friggatriskaidekaphobia.

Even if you personally don’t put stock in this fear, there are a lot of people who do.

According to CNBC, the Stress Management Center and Phobia Institute estimated that between $700 to $800 million dollars are lost every Friday the 13th because people are afraid to shop, travel, and conduct business.

Still, think it’s just a superstition? These events might be enough to convince even the most determined non-believer.
