The late Ian Lungold gives a presentation on the Mayan Calendar back in 2003. The talk encompasses a history of time and the intent of the creation cycle as perceived through ancient knowledge based on the mayan calendar.
Ed comment: Some dates given in this presentation are in question, off or at least delayed (on the "official" level), but it's an excellent lecture with many brilliant points for your considerations, especially the discussion around the role or the illuminati of the ruling elite at this particular time. One reason for the delay could be that it takes longer for things to manifest on the material level. There is no question that the economic "depression" that was discussed by Carl Johan Calleman a few years ago now has manifested, just slightly delay.
