The fear of Friday the 13th is called paraskavedekatriaphobia , a word derived from the concatenation of the Greek words Paraskeví (Παρασκευή) (meaning Friday), and dekatreís (δεκατρείς) (meaning thirteen), attached to phobía (φοβία) (meaning fear). The term is a specialized form of triskaidekaphobia, a simple phobia (fear) of the number thirteen appearing in any case.
According to the Stress Management Center and Phobia Institute in Asheville, North Carolina, an estimated 17 to 21 million people in the United States are affected by a fear of this day.
