It’s Friday 13th – the unluckiest day!
In 2017, it occurs twice (on January 13 and October 13), and there will be two Friday the 13ths per year until 2020.
On this date some people avoid flying on a plane, going to work, or even getting out of bed.
And it was on Friday, October 13. 1307 that King Philip IV of France had multitudes of Knights Templar captured. tortured into giving false confessions, and burned at the stake (Since he was deeply in debt to the order, he took advantage of the situation to gain control over them)
Their Grand Master Jacques de Molay, cursed the Pope and the King of France, and this spread misfortune down the ages.
The superstition around this day arose during the Middle Ages, and may have Biblical origins.
For example, Judas Iscariot, the apostle who betrayed Jesus, was the 13th guest at the Last Supper, the day before Christ’s crucifixion on Good Friday.
(Also in Norse mythology there was a 13th guest, Loki, who ruined a party of the gods, and caused the world to be plunged into darkness.)
Other biblical events that apparently occurred on a Friday include the beginning of the great flood, the confusion of languages at the Tower of Babel, the day Eve bit the apple from the Tree of Knowledge,
For hundreds of years, Friday has been considered the unluckiest day of the week, and Geoffrey Chaucer, in his Canterbury Tales, wrote: “and on a Friday fell all this mischance.”
In Britain, Friday was once known as Hangman’s Day because it was the day when people condemned to death were hanged.
As regards the number 13, it is considered unlucky in some cultures. It follows 12, which is seen as the number of completeness: there are 12 months of the year, 12 zodiac signs, 12 gods of Olympus, 12 hours of the clock, 12 tribes of Israel, 12 Apostles of Jesus, 12 Imams succeeding Muhammad, and so on.
In ancient cultures, the number 13 represented femininity, because it corresponded to the number of lunar (menstrual) cycles in a year. One theory is that, as the solar calendar triumphed over the lunar, the number thirteen became anathema, whereas another theory states that the number 13 was purposely vilified by the priests of patriarchal religions precisely because it represented femininity and was revered in prehistoric goddess-worshipping cultures.
