I took a fantastic two-day long seminar at the Adler Planetarium back in January of this year. I learned about about the Mayan Calendars (yes, that's plural), and how astronomy really fits in neatly with their calendars and other aspects of Maya life. I developed a 45-50 minute long presentation that, over the last year, I have given at many local libraries, astronomy clubs and a star party. It has been well-received at each venue. I condensed most of the major/important aspects of my presentation into a 10 minute long video: The truth about the Mayan Calendar Hopefully it will help those who watch it have more informed conversations about the Mayan Calender in the next couple of weeks.
