The unluckiest day in the Western calender, Friday the 13th, is here. This is the first Friday the 13th of 2018, and the second and the last one for the year will come in July. Below are some facts, myths and superstitions about this date.

1. The fear of Friday the 13th is known as friggatriskaidekaphobia which is also called paraskavedekatriaphobia.
