Another Friday the 13th came! Many superstition beliefs that this day is a bad luck for all of us.But the really strange thing is that most of the people who believe the day is unlucky offer no explanation at all, logical or illogical. As with most superstitions, people fear Friday the 13th for its own sake, without any need for background information.

The fear of Friday the 13th is called paraskavedekatriaphobia, a word derived from the concatenation of the Greek words Paraskeví (Παρασκευή) (meaning Friday), and dekatreís (δεκατρείς) (meaning thirteen), attached to phobía (φοβία) (meaning fear). This is a specialized form of triskaidekaphobia, a simple phobia (fear) of the number thirteen, and is also known as friggatriskaidekaphobia. The term triskaidekaphobia was derived in 1911 and first appeared in a mainstream source in 1953.

The fear of Friday the 13th stems from two separate fears -- the fear of the number 13 and the fear of Fridays. Both fears have deep roots in Western culture, most notably in Christian theology.

Thirteen is significant to Christians because it is the number of people who were present at the Last Supper (Jesus and his 12 apostles). Judas, the apostle who betrayed Jesus, was the 13th member of the party to arrive.



According to folklorists, there is no written evidence for a "Friday the 13th" superstition before the 19th century.[4][5][6] The earliest known documented reference in English occurs in an 1869 biography of Gioachino Rossini:
[Rossini] was surrounded to the last by admiring and affectionate friends; and if it be true that, like so many other Italians, he regarded Friday as an unlucky day, and thirteen as an unlucky number, it is remarkable that on Friday, the 13th of November, he died.

However, some folklore is passed on through oral traditions. In addition, "determining the origins of superstitions is an inexact science, at best. In fact, it's mostly guesswork." Consequently, several theories have been proposed about the origin of the Friday the 13th superstition.
