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. According to the Stress Management Center and Phobia Institute in Asheville, North Carolina, an estimated 17 to 21 million people in the United States are affected by a fear of this day, making it the most feared day and date in history. Some people are so paralyzed by fear that they avoid their normal routines in doing business, taking flights or even getting out of bed. “It’s been estimated that $800 or $900 million is lost in business on this day”.
On Friday the 13th of November 2015 Eight ISIS terrorists wielding AK-47s and wearing suicide belts carried out coordinated attacks at six sites around Paris, killing at least 129 people and wounding at least 352 others.
