Per many authorities, the Mayan Calendar ended on 12/21/2012.
For this past year, I'm learning over-and-over that time and space don't actually exist; but we are sense-based humans, so in our perceptions of reality, time and space seems to exist.
But...as we learn to live in the moment (due to increasing our awareness and consciousness), we are able to perceive that when we truly live in the moment, we are set free from time.

The ending of the calendar could serve as a confirmation to us....that yes, indeed, we are awakening, and that we are on the right path....of awareness... that time is an element of physical-dimension awareness; and as we become fully awakened, it will make sense; we will know that we are timeless, and all one. There is no beginning and no end -- There just is the Infinite perfect One.
