Superstitious? This Is Why Everyone Is Scared of Friday the 13th

Sometimes we just can't help but be superstitious. Broken mirrors, white lighters, black cats, spilled salt... it all, supposedly, brings bad luck. But the granddaddy of them all, Friday the 13th, has had people hiding behind locked doors for the past 100 or so years. So, why is Friday the 13th considered unlucky? Scroll down for everything we know!

On any Friday the 13th throughout each year, people may be afraid to leave their house because they're scared something bad will happen. Even weirder? This condition actually has a name, and it's paraskavedekatriaphobia, which means fear of Friday the 13th. But where did this bizarre myth actually come from?

To no surprise, it seems almost unbelievable. It's important to note, however, that we consider the number 13 and the day Friday unlucky for different reasons.

As for the 13th, there's apparently one theory associated with the Bible. Judas betrayed Jesus, and he ended up being the 13th guest at the Last Supper. Perhaps this is why it's considered unlucky to this day to have 13 people sitting at the dinner table.

The other theory, however, is a bit more mythical. In a Norse myth, 12 gods were having dinner at Valhalla when a 13th guest arrived unannounced. That guest was Loki, an evil and mischievous god who convinced another one of the gods to kill his brother. Yikes...

That said, these 13th guests have basically made history for their wrongdoings. For example, you sometimes won't see a 13th floor in a large building, and some planes don't even have a 13th row— all because it's considered to be bad luck.

But why is the day Friday so unlucky when there are six other days in a week? Even though it's arguably the best day of the week (hello, weekend!), Jesus was allegedly crucified on a Friday. Nineteenth-century American tradition also held all executions on Fridays, which really did not help the situation at all. 

And to make matters worse, Chaucer noted in The Canterbury Tales, "And on a Friday fell all this mischance." Spooky...

So, should we be worried about Friday the 13th? Probably not. It seems like it's just all in our heads, and just a running tradition that we can't seem to shake. Plus, we can't blame ourselves for thinking that being superstitious is really fun and mysterious.

On top of that, Friday the 13th doesn't exactly span to every culture. Italians consider Friday the 17th unlucky, while Greek and Spanish-speaking countries find Tuesday the 13th to be unlucky.

So far, none! However, we have two Friday the 13ths coming our way. The first one will be on Sept.13, 2019. The second one will be on Dec. 13, 2019. What a way to end the year...

And don't think 2020 will be any better. March 13, 2020 and November 13, 2020 will be equally eerie as well.
