It's Friday the 13th! This date has been associated with bad luck for centuries. Many people believe that this day is cursed and in an almost Halloween-like atmosphere, tell spooky tales about misfortunes that have taken place on this day. The fear of Friday the 13th has been called paraskevidekatriaphobia, from the Greek words Paraskeví (meaning "Friday"), and dekatreís (meaning "thirteen"), and while it may seem like an outdated concept to fear the day, the superstition still lives.

According to some estimations, the world loses $700 to $800 million in revenue on Friday the 13th because people do not want to conduct business. And it's not just that, 80 percent of the high rise buildings reportedly skip the 13th floor and many airports and hospitals skip gate 13 and room 13, respectively. The fear of the number 13 has also been given a scientific name: "triskaidekaphobia."

Several theories have been proposed about the origin of the Friday the 13th superstition. But the one that we like the most is that in numerology the number twelve is considered the number of divine organizational arrangement or chronological completeness, as reflected in the twelve months of the year, twelve hours of the clock day, twelve gods of Olympus, twelve tribes of Israel, twelve Apostles of Jesus, the twelve successors of Muhammad in Shia Islam, twelve signs of the Zodiac, the 12 years of the Buddhist cycle, etc., whereas the number thirteen was considered irregular, transgressing this completeness.

Nevertheless, today we feel like it could be a funny day if you forget about the bad things and superstitions and indulge in some funny phrases that we've gathered up for you regarding the date.
