Friday the 13th is a day that is considered unlucky in Western superstition. It occurs when the 13th day of the month in the Gregorian calendar falls on a Friday, which happens at least once every year but can occur up to three times in the same year. In 2023, the last Friday the 13th of the year lands on October 13th. This is the second Friday the 13th of the year, with the first one occurring in January. The next Friday the 13th of October will be in 2034, then 2045, and 2051.
