Triskaidekaphobia

An example of the phobia. The elevator does not have the "13th floor".

Triskaidekaphobia^{[n 1]} is the fear of the number thirteen. The number 13 has been linked to bad luck in the western superstition. Some buildings in the United States do not have a "13th floor."

The term was first used by Isador Coriat in Abnormal Psychology.^[1]

There is also a fear of Friday the 13th. This fear is called paraskevidekatriaphobia^{[n 2]} or friggatriskaidekaphobia.^{[n 3]}
