Mind Fuck: Day 10

Today I found out... The Mayans developed a calendar that had a unit called a "Baktun" which was 144,000 days long. They believed that after a great cycle of thirteen Baktuns the world would be destroyed and recreated again. Because their astronomical records were so precise, we can work out that the most recent great cycle started on Wednesday 8th September 3114BC.  This means that it - and, according to the Mayans, the world - will come to an end on Sunday 23rd December 2012. Pack your bags and don't say you haven't been warned...
