Paraskavedekatriaphobia

No, not a random collection of letters that look like they might mean something. It is actually a specialized form of triskaidekaphobia.

We have three times this year to remember this special word- today, in four weeks and again in November.

It is, as you might expect, the fear of Friday the 13th- and I don't mean the movie.

So shiver and fear, avoid ladders and black cats, and most of all, stay away from anyone named Jason.
