excerpt::Friday the 13th, 'the most widespread superstition'
The sixth day of the week and the number 13 both have foreboding reputations said to date from ancient times, and their inevitable conjunction from one to three times a year (there happen to be three such occurrences in 2009, two of them right in a row) portends more misfortune than some credulous minds can bear.
According to some sources it's the most widespread superstition in the United States today. Some people refuse to go to work on Friday the 13th; some won't eat in restaurants; many wouldn't think of setting a wedding on the date.
How many Americans at the turn of the new millennium actually suffer from this condition? According to Dr. Donald Dossey, a psychotherapist specializing in the treatment of phobias (and coiner of the term paraskevidekatriaphobia, also spelled paraskavedekatriaphobia), the figure may be as high as 21 million. If he's right, at least eight percent of Americans are still in the grips of a very old superstition.
LEGEND HAS IT: If 13 people sit down to dinner together, one will die within the year. The Turks so disliked the number 13 that it was practically expunged from their vocabulary (Brewer, 1894). Many cities do not have a 13th Street or a 13th Avenue. Many buildings don't have a 13th floor. If you have 13 letters in your name, you will have the devil's luck (Jack the Ripper, Charles Manson, Jeffrey Dahmer, Theodore Bundy and Albert De Salvo all have 13 letters in their names). There are 13 witches in a coven. ~ read more
