Friday the 13th

I always wondered where the fear of Friday the 13th came from. So according to Wikipedia here is a overview of why:

Phobia

The fear of Friday the 13th is called friggatriskaidekaphobia (Frigga being the name of the Norse goddess for whom "Friday" is named and triskaidekaphobia meaning fear of the number thirteen), or paraskevidekatriaphobia^[1][2] a concatenation of the Greek words Paraskeví (Παρασκευή, meaning "Friday"), and dekatreís (δεκατρείς, meaning "thirteen") attached to phobía (φοβία, from phóbos, φόβος, meaning "fear"). The latter word was derived in 1911^{[citation needed]} and first appeared in a mainstream source in 1953.

History

Consequently, several theories have been proposed about the origin of the Friday the 13th superstition.

One theory states that it is a modern amalgamation of two older superstitions: that thirteen is an unlucky number and that Friday is an unlucky day.

• In numerology, the number twelve is considered the number of completeness, as reflected in the twelve months of the year, twelve hours of the clock, twelve tribes of Israel, twelve Apostles of Jesus, twelve gods of Olympus, etc., whereas the number thirteen was considered irregular, transgressing this completeness. There is also a superstition, thought by some to derive from the Last Supper or a Norse myth, that having thirteen people seated at a table will result in the death of one of the diners.
• Friday has been considered an unlucky day at least since the 14th century's The Canterbury Tales,^[3] and many other professions have regarded Friday as an unlucky day to undertake journeys or begin new projects. Black Friday has been associated with stock market crashes and other disasters since the 1800s.^[6][7] It has also been suggested that Friday has been considered an unlucky day because, according to Christian scripture and tradition, Jesus was crucified on a Friday.^[8]

A theory by author Charles Panati, one of the leading authorities on the subject of "Origins," maintains that the superstition can be traced back to ancient myth:

The actual origin of the superstition, though, appears also to be a tale in Norse mythology. Friday is named for Frigga, the free-spirited goddess of love and fertility. When Norse and Germanic tribes converted to Christianity, Frigga was banished in shame to a mountaintop and labeled a witch. It was believed that every Friday, the spiteful goddess convened a meeting with eleven other witches, plus the devil — a gathering of thirteen — and plotted ill turns of fate for the coming week. For many centuries in Scandinavia, Friday was known as "Witches' Sabbath."^[9]

Social impact

According to the Stress Management Center and Phobia Institute in Asheville, North Carolina, an estimated 17 to 21 million people in the United States are affected by a fear of this day. Some people are so paralyzed by fear that they avoid their normal routines in doing business, taking flights or even getting out of bed. "It's been estimated that [US]$800 or $900 million is lost in business on this day".^[5] Despite this, representatives for both Delta and Continental Airlines say that their airlines do not suffer from any noticeable drop in travel on those Fridays.^[13]


Rate of accidents

There are conflicting studies about the risk of accidents on Friday the 13th. The Dutch Centre for Insurance Statistics (CVS) on June 12, 2008, stated that "fewer accidents and reports of fire and theft occur when the 13th of the month falls on a Friday than on other Fridays, because people are preventatively more careful or just stay home. Statistically speaking, driving is slightly safer on Friday the 13th, at least in the Netherlands; in the last two years, Dutch insurers received reports of an average 7,800 traffic accidents each Friday; but the average figure when the 13th fell on a Friday was just 7,500.^[14][15] However, a 1993 study in the British Medical Journal that compared the ratio of traffic accidents between Friday the 6th and Friday the 13th stated that there is a significant increase in traffic-related accidents on Friday the 13th.^[3][16] There are indications that there are more accidents on Fridays than average weekdays (irrespective of the date) probably because of alcohol consumption. Therefore it is less relevant for this purpose to compare Friday the 13th with any other 13th day of another month.
