Reading the Maya Long Count Date

The Maya Long Count Date consists of three calendars.

In Maya dating, the date reads ‘longest to shortest’ from left to right. Beginning on the very left, the ‘Long Count’ calendar date is written first, then the ‘Tzolkin calendar date’ and then lastly, the ‘Haab calendar date’.  Meaning, the Maya written date starts with the longest calendar’s count on the left, and then the ‘Tzolkin date’ is written, and then the ‘Haab date’.

For example, using the Maya calendar numbering system, a typical date would read as: / 4 Ahau / 8 Kumku

Here’s how the Long Count date works:

Maya long count dates are written out from left to right with five numbers which are separated by four periods, written as such:

The dating order is: the year is marked to the far left with the day being counted to the far right.

The ancient Maya represented these number values with their own beautifully designed hieroglyphs instead of using actual numerals, as in these examples: were-three-major-achievements-mayan-civilization_7146788d32ca00b9

The number on the right-most position is called the “k’in,” which counts single days, for example:,,, etc..

The Maya counted the days to 20.

The “k’in” counts up to 19 days and then goes back to zero, with counting picked back up by the next position, called the “uinal” (winals). This is the Maya equivalent of a month.

So counting up from the day would become

Example of Long Count date by Columbia Pictures.

Each “uinal” is a block of 20 days (k’in). After an ‘uinal’ is added to the count, the ‘k’in’ position then picks back up at 0 and again counts up to 19 before adding another ‘uinal’ on the 20th count.  So the day after would be and then, all the way up to until finally adding an ‘uinal’ to make

The ‘uinals’ count upward as well.

While the Maya generally used a vigesimal (base-20 counting system) in everything they did, the Long Count is really a mixed base-20 and base-18 system that represents the number of days since the start of Maya creation of the World. To make this work, they modify this slightly for the ‘uinals,’ which only counts up to 17 before rolling over at the count of 18 to the third position (middle), which is called the “tun.”

Each “tun” is 18 blocks of 20 days, which equals 360 days total.

A tun is approximately a year by the solar calendar. The ‘tuns’ in turn count up to 19 and then at the count of 20, rolls over into the fourth position from the right, which are called, “k’atuns.”

A k’atun is 20 blocks of 360 days, which adds up to 7,200 days, or just under 20 years.

The k’atun counts up to 19, before reaching 20 and rolling over into the final digit of the Long Count, called the “b’ak’tun.”

If the word, “b’ak’tun,” sounds familiar, it’s because on the modern date of December 21, 2012 on our calendar marked the end of the “13th b’ak’tun” of the Maya Long Count Calendar.

In other words, it’s the day the Maya long count date will read
On December 22, 2012 the Maya Long Count Calendar read as

Each “b’ak’tun” is 144,000 days long, which is just under 400 years.

To the ancient Maya, the 13th b’ak’tun represented a full cycle of creation according to their beliefs.

The Maya never made any apocalyptic prophecies about the “End of the World” or anything like that. The Long Count is an astronomical calendar that was used to track long periods of time, which the Maya called the “universal cycle.” Each of these cycles are 2,880,000 days long, which is about 7885 solar years.

The beginning of the 13th b’ak’tun was on August 11, 3114 BC on the Gregorian calendar or September 6, 3114 BC on the Julian calendar.

The 13th b’ak’tun marks the creation of the World for human beings, according to Maya Mythology.

The ancient Maya believed that it was on this “Creation Date” that “Raised-up-Sky-Lord” caused three stones to be set by associated gods at “Lying-Down-Sky, First-Three-Stone-Place.” Because the sky still lay on the primordial sea, it was black, the setting of the three stones centered the cosmos which allowed the sky to be raised and revealed the sun. The creation of the World inhabitable by humans.

The belief that the end and start of a calendaric cycle is going to trigger some event still inspires a myriad of prophesies about the end of the world. However, there is nothing to worry about. The final episode in the Maya Creation Myths concluded with the creation of humans with no further destruction/recreation cycles. Even though the Maya started their calendar based on their belief of the creation of the World, their calendar was nothing more than a means to record the date and events.

The Maya had the capacity to count millions of years into the future, but rarely used units that were larger than “b’ak’tuns.”
