We all know the superstition that the 13th day of the month if it is on a Friday, is unlucky. This is the most famous superstition in the world. Some people started to have a fear of this specific date, which nowadays is called paraskevidekatriaphobia. But where did this superstition come from?
The superstition of fear of Friday the 13th appeared and spread only at the end of19th century and – the beginning of the 20th century. Until then, the Fridays on the 13th day of the month were not considered anything exceptional. It is true that in the Western world, the number 13 was previously considered an unfortunate number, and Friday was an unfortunate day. Eventually, these two superstitions were simply merged into one.
