Common year starting on Thursday
This is the only common year with three occurrences of Friday the 13th, in February, March and November. The other type of year with three occurrences of Friday the 13th is a Leap year starting on Sunday which has three Friday the 13ths in January, April, and July. Also interestingly, with the exception of skipped leap years, leap years starting on Sunday falls exactly three years either side of two consecutive common years starting on Thursday; the most recent occurrence was 2012 between 2009 and 2015. From February until March in this type of year is also the shortest period (one month) that runs between two instances of Friday the 13th.
