As if 2020 could get any weirder, Nov. 13 falls on a Friday this year. Cue the black cats, ladders and mirrors. Here are some fun facts about Friday the 13th!

The Origin of the Fear

Friday the 13th has become a day of fear and superstition. The fear of the day has many possible origins, with a couple of the most popular origins being from the Bible and Loki, the Norse god of mischief. In terms of the Bible, the Last Supper consisted of 13 guests and people began to fear having 13 dinner guests because of that. This fear spread from dinner guests to life in general. Another dinner-based fear comes from Norse mythology with a story in which Loki tricked another god, Höðr, into killing his brother Baldr. Baldr’s death occurred at a dinner party for 12 gods and was interrupted by a 13th, Loki.

The Birth of a Genre

Friday, Feb. 13, 1970, is considered the birthday of heavy metal. This day marks the anniversary of Black Sabbath’s self-titled album. The term “heavy metal” had been referenced earlier than 1970 but Black Sabbath has been deemed the true father of the genre. Black Sabbath became the inspiration for many bands throughout the 50 years since the birth of its album, such as Metallica, Judas Priest, Iron Maiden and many more.

Look out for the Asteroid 

Researchers at NASA have taken note of an asteroid that is set to fly very close by Earth on Friday, April 13, 2029. This particular asteroid was discovered in 2004, and it was given a one in 60 chance of crashing into Earth, which would produce devastating effects. More data that has been gathered since 2004 says the asteroid will completely miss Earth but will be visible as it passes by. It is expected to zoom past Earth 18,600 miles above the ground and be visible in Africa, Europe and Asia. An event like this is not expected for another 1,000 years or so.
