So, Friday the 13th is considered to be an unlucky day. Fridays were regarded as unlucky, and I have always supposed this was because Friday was the day Christ was crucified.13 is considered unlucky because it follows 12, one of the “complete” numbers – twelve hours of the day, twelve months of the year, twelve tribes of Israel, twelve apostles of Jesus, twelve successors of Muhammad, twelve signs of the Zodiac, twelve deities of Olympus and the twelve years of the Chinese calendar. There is also a superstition, thought by some to derive from the Last Supper, that having thirteen people seated at a table results in the death of one of the diners.
The name of the fear of Friday the 13th is triskaidekaphobia. Gioachino Rossini was noted for being superstitious about Friday 13th and, indeed, he died on Friday 13th November. Usually a phobia is regarded as an “unreasonable fear” but if one actually dies was it unreasonable? The Knights Templar were harrassed and arrested en mass on Friday, 13 October 1307 and falsely charged with heresy, immorality and abuses.
In Finland their National Accident Day always falls on a Friday 13th, and in Holland they have fewer accidents on Friday 13th than on other days. People are thought to drive less and more carefully then.
On Friday 13th June 2014, there is also a full moon. This probably has nothing to do with bad luck, but it is an interesting fact nevertheless.
Have a happy and safe Friday 13th!
