Mayan dating system
This was similar to the Gregorian calendar in that it consisted of months, and within months, of days numbered consecutively.
However, unlike the Gregorian calendar, the haab cycle is made up of eighteen months of twenty days each, plus five days at the end of the year. The haab cycle thus consisted of 18×20 5 = 365 days, the integral number of days closest to the mean solar year of 365.2422 mean solar days.
THE LONG COUNT A Maya long count date is a modified vigesimal number composed of five places, e.g.
184.108.40.206.0, and interpreted as a count of days from some base date. THE TZOLKIN Sacred Calendar The tzolkin, known as the sacred calendar, is a cycle of 260 days.
The Maya calendar was adopted by the other Mesoamerican nations, such as the Aztecs and the Toltec, which adopted the mechanics of the calendar unaltered but changed the names of the days of the week and the months.A typical Mayan date looks like this: .2.6, 3 Cimi 4 Zotz. One of the ‘gears’ is called the tzolkin, or Sacred Round. The smaller wheels together represent the 260-day Sacred Round; the inner wheel, with the numbers one to thirteen, meshes with the glyphs for the 20 day names on the outer wheel.A section of a large wheel represents part of the 365-day year – 18 months of 20 days each (numbered 0-19).The Maya calendar uses three different dating systems in parallel, the (civil calendar). The tzolkin is a cycle of 260 days and the haab is a cycle of 365 days.Of these, only the Haab has a direct relationship to the length of the year. The tzolkin cycle and the haab cycle were combined to produce a cycle of 18,980 days, known as the calendar round. The “Calendar Round” is like two gears that inter-mesh, one smaller than the other.
