Friday The 13th

Friday the 13th is considered a day of bad luck all over the world.Even in the ancient days.The fear of Friday the 13th is called Friggatriskaidekaphobia/paraskavedekatriaphobia. Frigga is the goddess to whom Friday is named while triskaidephobia is fear for the number 13. But where did the superstition come from?Some theories which have been proposed  try to explain why people have phobia for Friday the 13th.
1.Number 12 is considered a number of completeness because of many reflections like 12 hours of the clock,12 signs of zodiac,12months of the year,12 tribes of Israel,12 disciples of Jesus and many others.Therefore 13 is considered irregular and odd.For example the 13th person in the last supper betrayed Jesus.
2.Friday was also the day Jesus was crucified,therefore making it a day of tragedy.That could be the reason why serious Christians have fear for Friday.
It`s no wonder most Hotels skip the 13th floor,airlines skip the 13th gate and room 13 in most hospitals is skipped.
There is at least one 13th Friday in a year and at most 3,is that a coincidence? Is fear for Friday the 13th a mere superstition of the west or it is true it really is a day of bad luck.
 About 21 million Americans are affected by this day making it the most feared day in Human history.
Do you fear Friday 13th?Is it just a mere superstition?Does it affect you?It affects people,others can`t travel on this day,fearing something bad may happen along the way.And other people can not go to work for fear they might get fired.You can also get sucked for not going to work,so is it really worth it?
I am told the best remedy for this phobia  is to walk around your house 13 times,again that is being superstitious,so there is no remedy at all. Just accept and move on!
