Didn't we just have a Friday the 13th? Yes, September 13th was the first in 2013. The next Friday the 13th isn't until June, 2014.
Why is Friday the 13th considered unlucky? Blame it on superstitions that have been handed down for centuries.
For hundreds of years the fear of Friday the 13th has haunted many who consider it just a downright unlucky day. Studies show that some people even go so far as to alter their plans for the day, choosing to avoid flying in an airplane, buying or selling stocks or even getting out of bed to face the day.
So just how did all this Friday the 13th superstition get started? According to one theory the superstition was made up of two older superstitions.
In numerology the number 12 is considered the number of completeness, as evidence the 12 months of the year, 12 hours of the clock, 12 gods of Olympus and so on. The number 13, however, is considered irregular.
And history has proven there have been numerous reasons why Friday is considered unlucky. And as far back as the 14th century Friday has been thought to be an unlucky day. In Canterbury Tales, some stories depicted bad things happening on this day which helped advance the superstition.
For Christians Friday was considered bad luck because it was the day Jesus was crucified. And of course in the 20th century, Black Friday is forever connected to the great stock market crash on a Friday in 1929.
Others point to the superstition as a modern day invention noting that references to Friday the 13th are nearly non-existent before 1907 which was the year Thomas W. Lawson's popular novel "Friday, the Thirteenth" in which an unsavory broker caused a panic on Wall Street on a Friday the 13th.
