2012 (MMXII) was a leap year starting on a Sunday. In the Gregorian calendar, it was the 2012th year of the Common Era, or of Anno Domini; the 12th year of the 3rd millennium and of the 21st century; and the 3rd of the 2010s decade.
This is the year of the Pineal Pirate and a time of high celebration. It was preceded by 2011 and followed by 2013 in some timelines, but, for many, 2012 was followed by 1920 as they began the cycle all over again.
