The Round Mayan Calendar Has an End?

The movie 2012 and a bunch of other hype say the world will end this coming Friday, December 21, 2012. When I first heard this nonsense, I remembered the round clay tablet my mother brought home in the early 1970s, from a visit to South America. I thought to myself, "The round Mayan calendar has an end?"

Think about it. Part of the definition of a circle is that it does not have an end.

You have heard of a circular argument, yes? Circular logic? Going round and round the mulberry bush? Coming full circle? The wheel of time? Going round and round and round in the circle game? The endless circle?

While researching the Mayan calendar a few years ago for an article, I discovered that it was constructed of several round clay tablets that interact together like gears in a mechanical clock. This photo shows that, a bit. How cool is that? This Friday, December 21, 2012 may be the end of one of the cycles of the Mayan calendar, but friends, a round calendar cannot come to an end. The definitions in geometry won't allow it.
