Word of the day - paraskevidekatriaphobe

I am starting a practice of writing any new word that I learn during the day.

Todays word - paraskevidekatriaphobe
Meriam Webster failed to have the meaning of this word.
WordSpy (www.wordspy.com) has it.
paraskevidekatriaphobia is fear of Friday 13th.

It is a Greek word. Paraskevi is the greek word for Friday. Dekatria is greek for 13th.
