Despite the buzz in pop culture and New Age circles, the world is not coming to an end on Dec. 21 that was predicted by ancient Mayans.

There's been so much confusion about the end date on the Mayan calendar that NASA set up a site to dispel the apocalypse rumor and a few other doomsday myths.

What is happening is a reset of a calendar used by the ancient Maya. But rather than marking the end of the world, Dec. 21 marks the end of an era in the Mayan long-count calendar.

So just as our calendar starts anew on Jan. 1, the Mayan long-count calendar enters a new era with the passing of Dec. 21.

Now that you don’t have to fear the end of the world, take some time to test your knowledge of the calendar that started all the doomsday hype.
