Friday, the 13th
Friday the 13th is considered an unlucky day in superstition. It happens when the thirteenth day of the month in the Gregorian calendar is a Friday.Its occurrence is between one and three times in the same year. Also, the 13th day of the month is more likely to be a Friday than any other weekly day.
The superstition surrounding that day may be originated from the story of Jesus Christ's last supper and crucifixion, in which there were 13 individuals present in the Upper Room on the 13th of Nisan Maundy Thursday, the night before his death on Good Friday.
For several other reasons, many people think that Friday is the unlucky day of the week, while 13 is conceded as an unlucky number. So, when a date has both of them, there is the belief that it is the unluckiest day of the year.
That is a motive why this day is associated with horror, plus the fact that 31, whose day in October is Halloween, can be obtained when alternating the algarisms of the number 13.
Comment if you believe that Friday the thirteenth is an unlucky day or not. Also, you can expose other reasons why it is considered a day of bad luck or recommend movie or other media in celebration of that day.
Independent of such opinion, as today is a date like that, I wish good luck to everyone!
Happy Friday the 13th!
