No month has a guaranteed Friday the 13th. Every year does though.
A month must begin on a Sunday in order to have a Friday the 13th..
It last happened in 1998. The only time this phenomenon can ever occur is in a February-March pairing in a non-leap year. Calendars repeat themselves in intervals of 6, 11, 12…, and 28 years; 2009 and 1998 happen to match up in an 11-year cycle. However, even not knowing that you can use the provided virtual calendar website to step back through the years to manually determine the most-recently occurring instance of this Friday the 13th pairing. Just use the navigation links to go back or forward in time. Incidentally, it will happen again in 2015.
February, March & November
Two consecutive months can have a Friday the 13th only if one of them is February and the other is March. This will occur in the year 2015.
February/March is the only time Friday the 13th will happen in back to back months given it is not a leap year since exactly 28 days is needed between the dates. The last time… that happened was in 2009 the next time will be 2015.
