Friday the 13th
Occurrence
In the 2010s, there were three Friday the 13ths in 2012 and 2015, and two in 2013, 2017, 2018 and 2019. In the 2020s, there will be three F13s in 2026, and two in 2020, 2023, 2024, and 2029. The rest of years have at least one F13 if there are fewer than two or three in the 2010s and 2020s. Assuming nothing is changed with the calendar, there are never more than three F13s in a year. There is a 28-year cycle that repeats when there is a F13 in February, March and November, and the current start of that pattern was in 2009. Although there is at least one F13 per calendar year, it can be as long as 14 months between two F13s. For the details see the table below.
