Is this different from english.stackexchange.com/questions/50615/…? – Andrew Leach Jun 17 '13 at 17:30
It can be either calendric or non-calendric. See Fillmore's lecture on "Time" from his Deixis Lectures. – John Lawler Jun 17 '13 at 17:31

It would depend on the context. It could mean different things. It could literally mean the past 730 days. If it were used near the beginning of 2013, it would more likely mean 2011 and 2012, but if it were used at the end (say, December), it would be referring to 2012 and 2013. Context is everything!

+1 for "context is everything". By the way, here are a few other possible contexts: In the past two academic years (as when a professor is asked, "How many courses have you taught in the past two years?"); in past two football seasons (as when a sportscaster says, "They've only been shut out once in the past two years"); in the past two hurricane seasons (when the meteorologist says, "There hasn't been a CAT III hurricane in the past two years") – you get the idea. – J.R.
