Some believe the superstition that Friday the 13th is a day of bad luck. Friday falls on the 13th at least once every year, but can occur up to three times a year.

Friggatriskaidekaphobia is derived from merging the words "Frigga" and "paraskevidekatriaphobia." "Friday" is believed to be named after Frigga, the Norse goddess of love and marriage, and triskaidekaphobia is the word for the fear of the number thirteen.
