Well, if you are superstitious today is a great day to stay in bed. Unless, of course, something bad happens while you are lying in bed. There are all sorts of warnings on Friday the thirteenth, but it actually has more to do with the number thirteen than a Friday. Ah, and this isn’t even Friday!
If you happen to be in a Jason movie then I suppose it is a bad Friday the 13th. However that said, any day you meet up with a character like Jason it’s likely to be a bad day. Besides Jason, you might want to avoid a building with a 13th floor, which most do not have even if they are taller than 13 floors. Ships will not sail if they have 13 crew members, including the Captain. It’s not a good idea to walk under a ladder today either. Naturally, it’s never a good idea to walk under a ladder anyway.
If, however, you come from the Mayan culture 13 is considered a lucky number. It was honored in their society so a Friday the 13th was the best day ever! But, I am not sure they knew what a Friday was… they probably had a different name for it.
In reality, Friday the 13th is just another day. We normally make our own bad luck if we suffer a bad luck day. The problem is that if you are looking for trouble, you will find it when you normally might walk right by it without even noticing it.
How to celebrate – If you are so inclined, stay in bed today. Have a nice day. Make up your own superstition.
