The '''{{PAGENAME}}''' is a very sophisticated calendar system used by the ancient Maya. It actually consisted of two calendars, one ritualistic calendar consisting of 260 days (13 times 20 days) called ''Tzolkin'', and a sun calendar consisting of 360 days (18 times 20 days) plus 5 unlucky or [[Unnamed Days|unnamed days]] (where the Tomb Raider Underworld level [[The Unnamed Days]] gets its name from) called ''Haab'', approximating the about 365¼ days of the sun year. Combined these two result in a cycle of 52 years after which the same dates repeat themselves. Additionally there was a ''long count'' for dates further in the future or past than these 52 years. (For further reading see [http://en.wikipedia.org/wiki/Maya_calendar Wikipedia].)

==Tomb Raider Underworld==
In [[Tomb Raider Underworld]] [[Lara Croft|Lara]] encounters a Maya Calendar puzzle that opens the entrance to [[Xibalba]]. She has to align the two calendar rounds to a specific date - the date when in Maya mythology the door to the underworld opens - to solve the puzzle and enter Xibalba.
