Today is Friday the 13th; celebrate accordingly

Today is Friday the 13th, so I’m serving up a list of three iOS apps to “celebrate” the big day (sorry, OS X fans, but I couldn’t find any such apps at the Mac App Store).

Friday the 13th from Pocketkai is a free app that calculates all Fridays the 13th for the next 50 years. (Every year has one to three Friday’s that fall on the 13th.)

Do you really believe that Friday the 13th is unlucky? An estimated 17-21 million folks are afraid of the date. Friday the 13th — How Unlucky is It is a free app that lets you tell if the most recent Friday the 13th was lucky or unlucky for you.

A lot of folks in Canada don’t fear the day. Friday the 13th Port Dover is the largest independent gathering in Canada. Over 200,000 people get together each Friday the 13th to celebrate with friends. There’s a free app that tells you about the history of Port Dover’s celebration and the latest Port Dover news.

No one seems to know exactly how the legend of an unlucky Friday started. The superstition surrounding this day may have arisen in the Middle Ages, "originating from the story of Jesus' last supper and crucifixion" in which there were 13 individuals present. There’s evidence of both Friday[ and the number 13 being considered unlucky, there’s no record of the two items being referred to as especially unlucky in conjunction before the 19th century.
