Friday the 13th 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. That happens at least once every year, but can occur up to three times in the same year. In 2017, it occurred twice, on January 13 and October 13. In 2018, it also occurred twice, on April 13 and July 13. There will be two Friday the 13ths every year until 2020; 2021 and 2022 will have just one occurrence each.
Fear of a particular date is called paraskevidekatriaphobia, fear for Friday 13 is called triskaidekaphobia.
One of the most popularised myths attempting to explain the origin of the Friday 13 superstition stems from events on Friday 13 October 1307, when hundreds of Knights Templar were arrested and burnt across France.
