There’s no definite reason to back up this Western Superstitious concept, however there are a few explanations that have since been developed to demystify this.
In the western culture, Friday the 13th is considered to be an unlucky day or a day of bad luck. Unreal because they are not known for having superstitious believes. Number 12 mostly symbolizes perfection, cosmic order, Christian facts and traditions e.g. Jacob’s 12 sons, 12 tribes of Israel, 12 days of Christmas and 12 great feasts. But why is this day considered so sinister?
This occurs if the 13th of the month falls on a Friday. These superstitions are associated with some history and cultural references. For instance the last supper and the crucifixion of Jesus.
There is reason to believe that there was the Presence of 13 people on the night before Good Friday, which is when Jesus was crucified.
Another reason is because during the last supper, Judas the disciple who betrayed Jesus was the last one to sit down on the table.
Loki, who had the ability to change his sex and shape was a 13th guest at a god’s dinner party. According to the Norse mythology, he ruined the party consequently bringing darkness into the world.
These fears have led to people dreading even sitting together if they are only 13 on the table, some buildings skipping the 13th floor when building and many other related occurrences.
Friday the 13th is actually an American horror Franchise comprising of 12 slasher movies. Games, novels, books are also available.
“Paraskevidekatriaphobia” has even been coined as a word to refer to the fear of Friday the 13th.
