Mayan Calendar - 13th Baktun

Dec. 21, 2012, marks the supposed end of the Maya calendar, which began sometime around August 11, 3114 B.C. Many believe that the end of the calendar, which happens to fall on the same day as the Winter Solstice, marks the end of the world. Doomsday prophets are banking on the end of humankind.

The notion states: There have been about 514 Leap Years since Caesar created it in 45BC. Without the extra day every 4 years, today would be July 28, 2013. Also, the Mayan calendar did not account for leap technically the world should have ended 7 months ago.

The National Geographic laid out a six-point argument disproving multiple end-of-the-world myths, one of which included that the Maya purportedly predicted the end of the world for 2012.

According to National Geographic, the Maya calendar does not actually end in 2012 and archaeologists contend that the Maya never viewed that year as the end of the world. Though the Maya viewed time as linear, with an understanding of past-present-future, they also saw time as cyclical. The calendar was a cyclical entity that would circle around again once one cycle was completed.

Dec. 21, 2012, is a momentous day. It's the time when the largest grand cycle in the Mayan calendar-1,872,000 days or 5,125.37 years-overturns and a new cycle begins, said Anthony Aveni, a Maya expert and archaeoastronomer at Colgate University in Hamilton, N.Y.

On that date, the Maya Long Count calendar runs out. The Long Count calendar began one Aug., 11, 3114 B.C. which was the dawn of the last creation period, according to National Geographic. On Dec. 22, 2012, the calendar will roll over again and start at Day Zero.

The Maya were known for their exceptionally advanced civilization and their developed understanding of astronomy and mathematics.


The Mayan calendar moves in cycles with the last cycle ending in December 2012. This is often interpreted as "the world will end on 21 December 2012, at 11:11 UTC".

Count down the seconds to “the end”

The best doomsday prophecies in history

The last day of the Mayan calendar corresponds with the Winter Solstice (or December Solstice), which has played a significant role in many cultures all over the world.

The Maya didn't invent the calendar, it was used by most cultures in pre-Columbian Central America – including the Maya – from around 2000 BC to the 16th century. The Mayan civilization developed the calendar further and it's still in use in some Maya communities today.
Wheels working together

The Mayan Calendar consists of three separate corresponding calendars, the Long Count, the Tzolkin (divine calendar) and the Haab (civil calendar). Time is cyclical in the calendars and a set number of days must occur before a new cycle can begin.

The three calendars are used simultaneously. The Tzolkin and the Haab identify and name the days, but not the years. The Long Count date comes first, then the Tzolkin date and last the Haab date. A typical Mayan date would read: 4 Ahau 8 Kumku, where is the Long Count date, 4 Ahau is the Tzolkin date and 8 Kumku is the Haab date.

The Haab

The Haab is a 365 day solar calendar which is divided into 18 months of 20 days each and one month which is only 5 days long (Uayeb). The calendar has an outer ring of Mayan glyphs (pictures) which represent each of the 19 months. Each day is represented by a number in the month followed by the name of the month. Each glyph represents a personality associated with the month.

The Haab is somewhat inaccurate as it is exactly 365 days long. An actual tropical or solar year is 365.2422 days long. In today’s Gregorian calendar we adjust for this discrepancy by making almost every fourth year a leap year by adding an extra day – a leap day – on the 29th of February.
The Tzolkin

The divine calendar is also known as the Sacred Round or the Tzolkin which means “the distribution of the days”. It is a 260-day calendar, with 20 periods of 13 days used to determine the time of religious and ceremonial events. Each day is numbered from one to thirteen, and then repeated. The day is also given a name (glyph) from a sequence of 20 day names. The calendar repeats itself after each cycle.
The Long Count

The Long Count is an astronomical calendar which was used to track longer periods of time, what the Maya called the “universal cycle”. Each such cycle is calculated to be 2,880,000 days (about 7885 solar years). The Mayans believed that the universe is destroyed and then recreated at the start of each universal cycle. This belief still inspires a myriad of prophesies about the end of the world.

The “creation date” for the current cycle we are in today, is 4 Ahaw, 8 Kumku. According to the most common conversion, this date is equivalent to August 11, 3114 BC in the Gregorian calendar or September 6 in the Julian calendar.
How to set the date

A date in the Maya calendar is specified by its position in both the Tzolkin and the Haab calendars which aligns the Sacred Round with the Vague Year creating the joint cycle called the Calendar Round, represented by two wheels rotating in different directions. The Calendar round cycle takes approximately 52 years to complete.

The smallest wheel consists of 260 teeth with each one having the name of the days of the Tzolkin. The larger wheel consists of 365 teeth and has the name of each of the positions of the Haab year. As both wheels rotate, the name of the Tzolkin day corresponds to each Haab position.

The date is identified by counting the number of days from the “creation date”.
A typical long count date has the following format: Baktun.Katun.Tun.Uinal.Kin.

Kin = 1 Day.
Uinal = 20 kin = 20 days.
Tun = 18 uinal = 360 days.
Katun = 20 tun = 360 uinal = 7,200 days.
Baktun = 20 katun = 400 tun = 7,200 uinal = 144,000 days.

The kin, tun and katun are numbered from zero to 19; the uinal are numbered from zero to 17; and the baktun are numbered from one to 13. The Long Count has a cycle of 13 baktuns, which will be completed 1.872.000 days (13 baktuns) after This period equals 5125.36 years and is referred to as the “Great Cycle” of the Long Count.
End of the World?

Will the world will end on 21 December 2012, at 11:11 UTC?

The Mayan calendar completes its current “Great Cycle” of the Long Count on the 13th baktun, on Using the most common conversion to our modern calendar (the Gregorian calendar) the end of the “Great Cycle” corresponds to 11:11 Universal Time (UTC), December 21, 2012, hence the myriad of doomsday prophecies surrounding this date.
The Maya

The Maya kept historical records such as civil events and their calendric and astronomical knowledge. They maintain a distinctive set of traditions and beliefs due to the combination of pre-Columbian and post-Conquest ideas and cultures. The Maya and their descendants still form sizable populations that include regions encompassing present day Guatemala, Belize, Honduras, El Salvador and parts of Mexico.
