Yes, there is an actual phobia of Friday the 13th! It’s called, Friggatriskaidekaphobia, and the etymology is broken down as “Frigga” related to the Norse goddess (Njörun) associated with Friday and the Greek word “triskaídeka” referring to the number 13 (thirteen) and “phobia” meaning fear. Put it all together and you have Friggatriskaidekaphobia = The Fear of Friday the thirteenth (13).
Friggatriskaidekaphobia is an anxiety-prone day for some, filled with superstition and the wait for a black cat to cross their path or to step on a crack to break their mother’s back. Why is it that there are always ladders around, just waiting for a person to walk under them or a mirror precariously positioned to fall and break when you walk near it?
