Friday the 13th has long been regarded as an unlucky day. Why do we choose this day in particular to fear for our lives?
In 1993, scientists found that there is a general increase in hospital admissions on Friday 13th.

Why is Friday 13th unlucky?
So is it just superstition or is there something more tangible at play?

History of Friday the 13th
The superstition around this day is thought to have come about during the Middle Ages, and may have Biblical origins.
Some historians have claimed it was the day on which Eve bit the apple from the Tree of Knowledge, the great flood began and the builders of the Tower of Babel.
In the New Testament there were 13 people present for Jesus's last supper. The other eleven desciples were sitted with Jesus Christ who made them twelve, before Judas entered and made them thirteen,Thursday, the day before Christ's crucifixion on Good Friday.
Geoffrey Chaucer made reference to the apparent unluckiness of the day, recording in his Canterbury Tales that it was bad luck to start a journey or a project on a Friday.

On Friday October 13th 1307 Philip IV of France arrested hundreds of the Knights Templar.
In his novel Da Vinci Code, Dan Brown cites the 14th century execution of Templar Grand Master Jacques de Molay, which took place on Friday the 13th. He cursed the Pope and the King of France, and this spread misfortune down the ages.
It is also possible that the publication in 1907 of Thomas W. Lawson's popular novel Friday, the Thirteenth played a part in disseminating the superstition. In the novel, an unscrupulous stock broker takes advantage of the superstition to create a Wall Street panic on a Friday the 13th.

The number 13 has been considered unlucky for many years, even before Christ. The number 12 is historically considered the number of completeness, while its older cousin, 13, has been seen as an outlier.
There are 12 months of the year, 12 gods of Olympus, 12 hours of the clock, 12 tribes of Israel, 12 Apostles of Jesus, 12 Descendants of Muhammad Imams, among many incidences of the pattern historically.

In many Western countries tall buildings are missing the 13th floor.
Houses often do not have a number 13, and many hotels, including the Carlton in London, miss out a thirteenth floor.
It is considered very unlucky for thirteen people to dine together, and the first to rise will reach serious misfortune - a superstition upheld by US President Roosevelt. He also refused to travel on Friday the 13th.
