The number 12 symbolizes completeness for numerologists and 13 has a reputation of a prime number steeped with irregularity. Thirteen is further tarnished by being the number of people at the Last Supper of Jesus. The Turks went so far as to ban the number from their language and the Vikings feared that if thirteen guests sat to dinner, all of them would die within a year under the curse of Loki, their god of mischief. Some humans have rejected this belief as superstition.Manhattan has a both East and West 13th Streets, however most high-rises on that fabled island are missing the 13th floor.
Many superstitions have their base in gambling and many gamblers exhibit an extraordinary fear of the #13 aka triskaidekaphobia.
There are usually 1-3 Friday the 13ths in a calendar year.
Today is one of them.
Unlike the West Thais consider the number 4 unlucky, although you’ll notice on Thai Air flights there is no row 13.
Personally I think 13's reputation comes from the age at which Jewish boys used to be circumcised and nothing is more unlucky for a man than losing a piece of your penis, unless you’re a ka-toey.
Black Sabbath also released their first album on Feb. 13, 1970.
The date had nothing to do with ladyboys.
Although with Ozzie you can never be sure.
