121212

You've probably been hearing about the 2012 phenomenon in the months leading up to December. Unlike 11112011,  this comprises a range of eschatological beliefs according to which cataclysmic or transformative events will occur on 21 December 2012. This date is regarded as the end-date of a 5125-year-long cycle in the Mesoamerican Long Count calendar.

Various astronomical alignments and numerological formulae have been proposed as pertaining to this date, though none have been accepted by mainstream scholarship.

Here are a few events that actually did (or will) take place...

• The official opening of the New Doha International Airport, in Qatar
• World Hoop Day
• One or more events associated with Anonymous
• Aaron Rodgers Day in Wisconsin
