The Fear of the Number 13
Triskaidekaphobia is the fear of the number 13. We have all heard of it, and many have heard rumors as to its origin, but do we really know the extend to which this superstition reaches worldwide, and for how long this fear has existed?
From the vikings, to the disciples, to the Knights Templar, to the Lunar calendar, there are many theories of the origin of Triskaidekaphobia. The myriad of occurrences of 13 portrayed in a negative light have furthered the superstition to travel around the world and increase its intensity.
Let's dive into the mysterious number 13...
The Fear of 13
The word triskaidekaphobia comes from greek: 'tris' meaning 'three', 'kai' meaning 'and', 'deka' meaning 'ten', and 'phobia' as we know meaning 'fear'. It is the fear of the number 13.
A specific fear of Friday the 13th is called paraskavedekatriaphobia or friggatriskaidekaphobia.
Related phobias include arithmophobia or numerophobia, which is the general fear of numbers, and hexakosioihexekontahexaphobia the fear of the number 666. Also, Tetraphobia, is fear of the number 4, a number considered quite unlucky in Korea, China, and Japan.

Possible Origins of this Worldwide Phobia - Why are we afraid of 13?
- Ancient man's counting method could be the very earliest cause of the 13 fear. Counting was done using ten fingers and two feet (presumably covered with a shoe). Anything beyond the countable 12 was deemed "unknown" and therefore suspect. In English, we have distinct names for the numbers one through twelve.
- Perhaps the 13 superstition stems from the Last Supper. At that meal 13 people sat a the table. Judas, the disciple who betrayed Jesus, was the 13th to sit at the table. This may also be the cause for the superstition that if 13 people sit down to a meal, then one will die within the year.
- The is a a Norse myth about 12 gods who had a dinner party at Valhalla, their heaven. A thirteenth - uninvited - guest attended the party. The 13th guest was the mischievous Loki. Once there, Loki tricked Hoder, the blind god of darkness, to shoot Balder the Beautiful, the god of joy and gladness, with a mistletoe-tipped arrow, killing him.
- The thirteen superstition may also be linked to that fact that a luni-solar calendar has 13 months in some years, while the solar Gregorian calendar and lunar Islamic calendar always have 12 months in a year.

The LUCKY Child 13
A surprising twist
With so much unluckiness about the number 13, it may be is surprising to some that superstitions say that 13 is not always unlucky. Those who are superstitious believe that children who are born on the 13th of any month shall be LUCKY in all of their ventures in life.
This is excellent news since I was one of those children!
Early American 13s (or so the British said)
As Printed in a London Newspaper in 1776
The number 13 came up many times surrounding the Americans at the time of the American Revolution. How much of this was intentional, versus coincidental, we will never know.
Thirteen is a number peculiarly belonging to the rebels. A party of naval prisoners lately returned from Jersey say that the rations among the rebels are thirteen dried clams per day; that the titular Lord Stirling takes thirteen glasses of grog every morning, has thirteen enormous rum-bunches on his nose, and that (when duly impregnated) he always makes thirteen attempts before he can walk; that Mr. Washington has thirteen toes on his feet (the extra ones having grown since the Declaration of Independence,) and the same number of teeth in each jaw; that the Sachem Schuyler has a top-knot of thirteen stiff hairs, which erect themselves on the crown of his head when he grows mad; that Old Putnam had thirteen pounds of his posteriors bit off in an encounter with a Connecticut bear, ('twas then he lost the balance of his mind); that it takes thirteen Congress paper dollars to equal one penny sterling; that Polly Wayne was just thirteen hours in subduing Stony Point, and as many seconds in leaving it; that a well-organized rebel household has thirteen children, all of whom expect to be generals and members of the High and Mighty Congress of the "thirteen United States" when they attain thirteen years; that Mrs. Washington has a mottled tom-cat, (which she calls, in a complimentary way, 'Hamilton,') with thirteen yellow rings around his tail, and that his flaunting it suggested to the Congress the adoption of the same number of stripes for the rebel flag.

Why is FRIDAY the 13th especially unlucky? - (paraskavedekatriaphobia or friggatriskaidekaphobia)

The Thirteen Club
An effort to end the superstition
In 1881, a group of rationalists joined together in forming The Thirteen Club. Their goal was to debunk the 13-at-table myth by dining once a month with 13 at each table, to show that no more of them died than in any other group. Though it took a year to recruit the first 13 members, by 1887 The Thirteen Club was 400-strong, with five U.S. Presidents as honorary members.
A copy of Robert Green Ingersoll's toast at the December 13, 1886 dinner is available online. It ends with:
"We have had enough mediocrity, enough policy, enough superstition, enough prejudice, enough provincialism, and the time has come for the American citizen to say: "Hereafter I will be represented by men who are worthy, not only of the great Republic, but of the Nineteenth Century."
