2012 Mayan Calendar 'Doomsday' Date Might Be Wrong 144

astroengine writes "A UC Santa Barbara associate professor is disputing the accuracy of the mesoamerican 'Long Count' calendar after highlighting several astronomical flaws in a correlation factor used to synchronize the ancient Mayan calendar with our modern Gregorian calendar. If proven to be correct, Gerardo Aldana may have nudged the infamous December 21, 2012 'End of the World' date out by at least 60 days. Unfortunately, even if the apocalypse is rescheduled, doomsday theorists will unlikely take note."

      Indeed, no one seems to be able to calculate this. When they first tried it came to sometime in 2013. Then it got moved to 2012 for about 15 years. Then for five it was 2013 again; but no one seemed to pay attention to that five years. Then as you said, they recalculated and found it to be off by 4,000.

      What I don't understand is, the mayan numerical system is positional (it has the equivalent of a zero); how could their calendar have an end date? Were they still alive today, they could have just added another position.

        actually, they have a circular calendar. Just that most people don't quite get the concept that once it reaches their "last" date, it just goes back to the first date and keeps going.

        And the people who do get it are riddled with nutjobs that believe that a new age is upon us or something like that.

      • I always refer to it as the Mayan Y5K problem.

        their computers(real people) couldn't calculate beyond a certain point so that became the final end date. Just like Y2K. lazy programmers cause the world to burn.

      • Mayan prophecies refer to dates several thousand years farther in the future than the date at the end of the popular Mayan calendar. Basically, all that you need when the calendar rolls over is just adding another character or getting a bigger stone, and the Mayans didn't have to worry that they'd have to upgrade all their abacuses to Stone 2K compliance.

      If by they you mean the Maya, then, no, they didn't predict the end of the world.

      They had a calendar which has a cycle expire at a particular time. The assignment of the "end of the world" or similar apocalyptic significance to that cycle expiration is something that was done in the 20th Century by New Age writers.

        The Mayans had a Long Count calendar which was based on how many days since the day they believe creation started. They believed that this age was the fourth world and the fifth would start at the end of the Long Count. Now I'm not up to speed on the specifics but I don't think scholars have figured out what the Mayans thought would happen at the start of the fifth world.

          They believed that this age was the fourth world and the fifth would start at the end of the Long Count.

          The first half is correct. The Maya did believe that this was the fourth -- and only successful -- creation, that followed three prior, failed attempts at creation.

          The second half is less correct. First, the Long Count doesn't end (or at least not in the currently-expected lifetime of the universe and several orders of magnitude more; the abbreviated expression that was all that was needed to record current dates does 'run out', similar to the Y2K problem, but the Long Count has many higher positional cycles that were used in writing future dates, and occasionally used in writing current dates in ceremonial contexts.)

          Second, there is no evidence that the Maya expected the current creation to end at any particular time; and there are concrete indications (in the form of predictions of events in the current creation that did require the use of higher-order cycles) that if they did expect the current creation to end, it wasn't at the point where Long Count dates counted from the beginning of the current creation would begin to need to use the higher-order cycles that weren't conventionally used to express current dates.

        Yes, this was like the Engineer of the Mayans, which used limited resources to describe the calendar. Now that the resources are almost done (and since no other Mayan Engineer has been able to update the Y2012 bug), then everyone speculates about the mess that this is going to cause.

    The most damning evidence against the "doomsday" is the fact that at least one Mayan king wrote about how he hoped people will still celebrate him in, then he gave a date, a date several thousand years after the end of the Mayan long calendar. So, did he not get the memo that the world would have been destroyed thousands of years before that date? Was he just oblivious? Seems contrary to assume he was clueless, since the only reason we think the Mayan calendar predicts the end of the world is the assumption that they were all-knowing and all-seeing, by virtue of not being us.

    Not the end of the planet, solar system, galaxy, universe, time or whatever is supposed to occur in 2012 (of course, those things will inevitably end, as well). However the inevitable end that I'm referring to is the end of a period of time that can be represented by a calender. I have never understood why the end of the Mayan calendar has to be the end of anything... I mean, The Dilbert calender on my desk ends on December 31st of this year... I wonder if I should attach any cosmic significance to that?
