Friday the 13th has everyone asking…

Posted by Collen on Fri November 13, 2015 in Vaalnest News.

Vaalnest reviews a few weird facts about the popular day. Did you know, the longest period that can occur without a Friday the 13th is fourteen months, either from July to September the following year being a common year starting on Tuesday (e.g., between 2001–02, 2012–13, and 2018–19), or from August to October the following year being a leap year starting on Saturday (e.g., between 1999–2000 or 2027–28).

Friday the 13th, also known as Black Friday is considered an unlucky day in Western superstition. It occurs when the 13th day of the month in the Gregorian calendar falls on a Friday. This year is a special one for Friday the 13ths, let us highlight top facts that surround this day:

  •  You may have heard of the word paraskavedekatriaphobia, (also known as friggatriskaidekaphobia). Those are the scientific terms for fear of Friday the 13th, additionally Triskaidekaphobia is actually a fear of the number 13.
  • It's not clear when or why Friday the 13th became associated with bad luck. The association may be biblical, given that the 13th guest at the Last Supper betrayed Jesus. His crucifixion was the next day, apparently a Friday.
  • Hotels and hospitals often skip the 13th floor, and even airports quietly omit gate 13 sometimes.
  • This year marked another year where we had three Friday the 13ths occuring. They were recorded in February, March and November.
  • Why does the Friday the 13th superstition stick so firmly in our minds? According to Thomas Gilovich, who chairs the department of psychology at Cornell University, our brains are almost too good at making associations.
  • If anything bad happens to you on Friday the 13th, the two will be forever associated in your mind, and all those uneventful days in which the 13th fell on a Friday will be ignored," Gilovich said in a statements.
    Interestingly for pagans, 13 is actually a lucky number. It corresponds with the number of full moons in a year.
  • Did you know according to the Stress Management Center and Phobia Institute in Asheville, N.C. it was estimated that hundreds of millions of dollars, up to $900 million to be exact are lost due to people's fear of flying or doing the business as usual that day, though that number isn't backed up with other estimates.
