It's a mighty big word for a superstition. According to the following Wikapedia definition paraskavedekatriaphobia is the fear of Friday the 13th.

"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."

Wow, what a mouthful. Personally I like Friday the 13th. 1.Because Friday are the threshold to the weekend. 2. Fridays were when my Mom went to the grocery and we got to have new cookies in the house. It was always fun to see what surprises were in the grocery bags. 3. Friday nights were High School football games and the chance to see my sons preform in the band. 4. Friday nights have often been the time weekend adventures began and begin. 5. Today I am hoping that this Friday the 13th will be extra special because I am praying that my son, Jim gets good news about his eye and vision. 6. This Friday the 13th leads us into Valentines Day!

Lots of reasons to think positively about Friday the 13th. Plus come to think of it, even though I can't pronounce them I have learned a couple of 50 cent words: paraskavedekatriaphobia and friggatriskaidekaphobia and triskaidekaphobia.

Okay, I confess. Just to be on the safe side I did eat some Lucky Charms!

Happy Friday the 13th!
