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, which happens at least once every year but can occur up to three times in the same year. For example, 2015 had a Friday the 13th in February, March, and November; 2017 through 2020 had two Friday the 13ths each; 2016, 2021 and 2022 had just one occurrence of Friday the 13th each; 2023 and 2024 will have two Friday the 13ths each.[1]
