This could be a long day for you if you’re a superstitious person. It’s kind of a double whammy.

First of all, it’s Friday the 13th. Long before some dude name Jason donned a hockey mask and was the main character in a slasher movie name “Friday the 13th,” it was a day that people looked on as bad luck.

As if that’s not enough, look up. Yep, that’s a full moon. So, a full moon on Friday the 13th. That hasn’t happened in — get this — since 2014.

Of course, if you’re going to hide under the covers all day and avoid this superstition double play, can I ask why?

Do you know why you think Friday the 13th and a full moon are evil? Or have you always just heard that’s the way it is.

I was just curious enough to do a couple of quick Google searches. Not a real deep dive of research mind you, but a quick glance. And it’s a good thing, too, because if you wanted to spend a lot of time on it, rest assured you’d end up with a long list of possibilities.

Not that this has ever happened on the Internet before or anything, but there are some points of disagreement.

Friday the 13th combines the overall “unlucky” number 13 with Friday.

The most common explanation seems to go back to biblical times.

The fact there were 13 people around the table at the Last Supper, with Judas thought to be the last — the 13th — to arrive, combined with Jesus then be crucified the next day — Friday — makes Friday the 13th a bad combination.

One web site listed bad things that have happened on Friday the 13th throughout history. But, with as long as divisive history has been, I bet you could find an equally long list for, oh, let’s say Tuesday the 21st.

Having said that, some researchers estimate that at least 10% of the U.S. population fear the number 13.

Even more aren’t wild about Friday the 13th.

Perhaps the most fun part of Friday the 13th is the word for fear of Friday the 13th – paraskevidekatriaphobia.

One tidbit of lore is that the doctor who came up with the word told his patients who have the disorder that if they could pronounce it, they will be cured. I don’t know about that, but if you work that word into your next game of Scrabble, I can almost guarantee you a win.

As for the full moon, the Google searches there are even more confusing.

It’s not so much that people consider it bad luck, just that many people contend it brings out the worst in people.

Jails and emergency rooms among the places that reportedly have increases in business during full moons.

Perhaps best known though would be the fact that it’s a full moon that brings out the beast in the werewolves of the world. One viewing of the movie “An American Werewolf in London” was all I needed to be just a little bit leery every month, let alone on Friday the 13th.

Of course, without werewolves coming out with a full moon, we never would have had the Warren Zevon song “Werewolves of London”, and the world would be a lesser place without it.

The full-moon doesn’t have the full bad image that Friday the 13th carries around.

Some say it improves hunting and fishing. It’s the star of many songs and movies. The full moon has been romanticized as much as it has been ostracized.

And let’s face it, much like bad events on Friday the 13th, I think you could pick most any time of the lunar phases and you’d find crazy things happening.

It just comes in handy when the moon is full to blame it on that.

I’ll leave it to the scientist to decide if it’s the stronger gravitational pull from the moon when it’s shiny bright and full.

All I know is that for the rest of this Friday the 13th, even the nighttime that is being illuminated by the full moon, I will not walk under a ladder, break a mirror, spill any salt, cross paths with a black cat or open an umbrella inside.

Hey, I don’t want to push my luck.
