Very good mini documentary about the mayan calendar and how it works

In this interview Graham talks about the maya prophecy and the possible implications of the prophecy.

Totally unconvincing. this guy claims that the only thing that WILL happen is a ''simple planetary alignment'' and he is so wrong with that. there is NO  planetary alignment on that date. There is however according to John Major Jenkins n alignment of our solar system with the galactic center, which is a different thing.
