How did we start fearing Friday the 13th? Some historians point to The Last Supper on the Thursday before Christ died as the event which triggered this ongoing taboo. There were 13 guests at that final meal before Jesus was crucified the next day. So apparently Christians began interpreting the two disparate things as disastrous when brought together.

Other historians trace this fear all the way back to 1780 B.C. when the Code of Hammurabi (282 laws which set up guidelines for everything from property rights and criminal behavior to slavery and divorce, and which also included bizarre and gruesome forms of punishment) was enacted without a 13th law. Bad things followed!

Friday was supposedly also the day on which Eve offered Adam that heinous apple and we all know what happened after that! But not everyone has a fear of Friday the 13th, or the number 13 in general. My dad considered thirteen to be a lucky number, as do many people in Italy, where my dad grew up.

Some sources indicate that only around 10 percent of Americans even believe that Friday the 13th has any incidental impact at all. Since there has never been a definitive study done on the effect of Friday the 13th on societal events on a large scale, no one can say with any certainty at all what kind of luck it may bring, good or bad.

But just to be on the safe side, I wouldn't walk under any ladders, holding a black cat, with an open umbrella! Happy Friday the 13th!
