Can Friday the 13th fall in consecutive months?

Answer 1

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.

Answer 2

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.

Answer 3

There can be one, two or three Friday the 13ths in a year. For consecutive months, it can only happen in a non-leap year with February and March both having a Friday the 13th. It can happen as close as 6 years and at most 11 years. Over the past 60 years, here are the years it happened:

1953

1959

1970

1981

1987

1998

2009

Answer 4

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.

Answer 5

All months can have a Friday the 13th at some point. There are either one, two or three in any year.
