Whenever I go on one of my “The-History-of-Mexico-Is-The-Most-Ignored-Of-The-Tragic-Spectacular-and-Misunderstood-Histories” overtures, the above statement would well-summarize one of my main theses. Facesmack and high five at the same time, Monsieur Zag.
I have a diary (yes, I still buy page a day diaries because, whatever) that has a year planner for 2013 so I guess we’re all safe until the end of… wait… it’s doesn’t go to 2014 so WE’RE ALL GOING TO DIE AT THE END OF 2013! OH NO!
I’m not quite sure how far in advance the Mayans were supposed to be planning. I’d say they thought that they had plenty of time to work on the next calendar before it was needed because they had hundreds of years to get around to it.
Any time someone’s mentioned the Mayans to me in person I’ve done the thing with my calendar and feigned fear until giving them ‘a look’. I do not get invited to many parties.
