| The ancient Mayan calendar has long been a source of fascination for modern scholars. And many say that the calendar holds the key to a greater understanding of our planet, our collective welfare, and our place in the cosmos. The countdown to the 13th Bak'tun - the mysterious Mayan "end of days" on December 21, 2012 - is included for each month as well. Proceeds support Maya Exploration Center, a non-profit research and education center. | |
