Triskaidekaphobia On Friday The 13th

Friday The 13th Unlucky

Today is Friday the 13th which is considered unlucky by many superstitious people in western culture. But why?

Friday the 13th Superstition

Well, the number 12 is considered a “perfect number” by mathematicians and adding one more could be considered making a perfect number unlucky.

Also, it is believed that Jesus was crucified on Friday and several late 19th Century English language sources relate the “unlucky” number thirteen to the Last Supper where Judas, the disciple who betrayed Jesus, was the 13th to sit at the table.

So the combination of both Friday and the 13th came to become considered an unlucky superstition, particularly in the United States and the United Kingdom.

The Friday the 13th superstition is so prevalent in the U.S. that many hotels and high-rises skip the 13th floor altogether.

Some people irrationally fear Friday the 13th so intensely that they suffer from the psychological disorder friggatriskaidekaphobia which is a combination of the fear of the number 13 (triskaidekaphobia) and the number 13 falling on a Friday (from Old Norse Frigg).
