Paraskavedekatriaphobia - The fear of Friday the 13th is called paraskevidekatriaphobia, 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). The term triskaidekaphobia derives from the Greek words “tris”, meaning ‘three’, “kai”, meaning ‘and’, and “deka”, meaning ‘ten’. the whole word means three and ten. The word was derived in 1911 and first appeared in a mainstream source in 1953.

 ^{Friday the 13th occurs when the thirteenth day of a month falls on Friday, which superstition holds to be a day of good or bad luck. In the Gregorian calendar, this day occurs at least once, but at most three times a year. Any month’s 13th day will fall on a Friday if the month starts on a Sunday. In 2009 this applies to the months of February, March, and November. The next year to have three Friday the 13th dates will be 2012.}

^{I consider Friday the 13th to be a GOOD LUCK day!!!}
