Can Friday the 13th fall in consecutive months?

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.
