If you are scared of the number 13 you have Triskaidekaphobia. Personally, I am afraid of that word! It is believed that Friday the 13th got off to a bad start as the day that Able killed Cain. At least it was a bad day for Cain. The Code of Hammurah omitted the 13th when it came to making laws. Many buildings do not have a 13th floor (well they do have but they don’t label one as such). And Captains would not put to sea if they had a crew of 13. So if today is bad luck for you, even though we generally make our own bad luck, then you might want to avoid doing much today. If you meet a guy named Jason, run!
How to celebrate – Go back to bed and wait for the 14th. Observe Backwards Day today making it the 31st. Just get through your day anyway you can.
