Details of Phobia:
Every few years, there is a day that you call off from work, hide under the covers, and count the hours until Saturday. When you have paraskavedekatriaphobia, your fear of the Friday the 13th is taking over your life for a few days a year – if you're lucky. This is a day to be feared and to be avoided at all cost – just like the movies of the same name.
