The Maya used a yearly solar calendar that was fairly precise, using 18 months and 20 days per month, with five additional unlucky days at the end, which totals to 365 days. The Maya did not take into account the additional 1/4 day, which we take into account through leap year, because it was not important for them. They additionally had a 260 day ritual calendar which worked in conjunction with the 365 day calendar to create a 52-year cycle. They also used a Long Count calendar which counts the number of days since the creation of the world on August 13, 3113 BC. This calendar returns to zero in 2012, which has caused an Apocalypse scare. However, this stems from a misunderstanding of the calendar, because the calendar is generally abbreviated to 5 places, when in reality there are over 40, so the calendar will continue after this date.  The calendar is written with five numbers with a period between each, such as 5.4.3.2.1. Each of the numbers between the period represents a place, since the Maya number system was base-20. In this date, for example, the 1 represents 1 days, the 2 represents 2*20 days, the 3 represents 3*360 days, the 4 represents 4*7,200 and the 5 represents 5*144,000. Each digit except the second (2) and the last (5) goes to 19 before returning to zero. The second only goes to 18 and the last only goes to 13. The original date for the world was 13.0.0.0.0, which will be the same date on December 21, 2012, and the reason for the Apocalypse scare.
