This is the second month in a row we’ve had a Friday the 13th.  That occurrence doesn’t roll around all that often, as it can only occur in March on a year that isn’t a leap year.  Some quick calculations indicate that the next one won’t roll around until 2026.  Looking further ahead through the rest of the century, the remaining occurrences are in 2037, 2043, 2054, 2065, 2071, 2082, 2093, and 2099.
