Two sequential Friday 13ths can only happen on Feb & March, and only in
non-leap years. So, i would guess it happens 3/28 years, or about 11% of
the time.

Good morning all, and a happy 2015 to everyone.
Looking at my diary this morning, I noticed that 2015 is a bit unusual
in having Friday 13 in consecutive months: February and March.
Does anyone know how often this occurs, when was the last time, and
when is the next time it will happen?
(And no, I don't place any particular significance in the day!)
Cheers, John
