For non-believers, this year's second — and final — Friday the 13th is just the start of a weekend. However, for the estimated twenty million people in the US, and scores more worldwide, that suffer from "friggatriskaidekaphobia," or "paraskevidekatriaphobia," November 13, 2020, will be fraught with bad luck. Though some of the fear can be blamed on the Friday the 13th movie franchise, the day's bad reputation began long before the film’s hockey-masked villain, Jason Voorhees, made an appearance.
