Friggatriskaidekaphobia is the term that describes the fear of Friday the 13th. There are two root words in this expression. Frigga is the name of the Norse Goddess for whom Friday took its name. Triskaidekaphobia refers to the fear of the number thirteen.
There is an extremely popular horror series about the day, and mentioning Friday the 13th can instill frightened looks. But why is this day so feared?
Here are some theories and superstitions surrounding Friday the 13th:
- Thirteen is an unlucky number, and Friday is an unlucky day, are two older superstitions that merged together.
- In numerology, the number twelve is the number of completeness. The number thirteen is irregular and messes up the completeness of twelve.
- Having thirteen people sit down to dinner - like in The Last Supper and a lesser known Norse myth - will result in the death of one of the people seated around the table.
- Jesus Christ was crucified on a Friday.
- Hundreds of members of the Knights Templar were arrested in France on October 13, 1307.
