Records of the superstition are rarely found before the 20thcentury, when it became common. So why do people think Friday the 13this a fateful day? It’s probably the combination of two older superstitions: thirteen is and unlucky number and Friday is an unlucky day.
In numerology, the number twelve is considered the number of completeness, the twelve months of the year, twelve hours of the clock, twelve gods of Olympus, twelve Apostles, etc. Whereas the number thirteen was considered irregular, breaking this rule of completeness. Another superstition, thought by some to derive from a Norse myth is that having thirteen people seated at a table will result in the death of one of the diners.
What’s your lucky number and are you superstitious about it? And more importantly, do you suffer from friggatriskaidekaphobia???
