The Aztec calendar was an adaptation that the Mayan calendar. It had a 365-day farming calendar, and a 260-day sacred calendar. (This is a digital composite. Color included for visibility.)
Among their various other accomplishments, the old Mayas invented a calendar of remarkable accuracy and complexity. At ideal is the old Mayan Pyramid Chichen Itza, Yucatan, Mexico. The Pyramid that Kukulkan in ~ Chichén Itzá, built circa 1050 was developed during the so late Mayan period, when Toltecs native Tula came to be politically powerful. The pyramid was provided as a calendar: four stairways, each with 91 steps and a communication at the top, make a full of 365, equivalent to the variety of days in a calendar year.
The Maya calendar was embraced by the other Mesoamerican nations, such as the Aztecs and the Toltec, which embraced the mechanics the the calendar unaltered but readjusted the surname of the work of the week and also the months. One Aztec calendar stone is shown over right.
The Maya calendar uses three various dating systems in parallel, the long Count, the Tzolkin (divine calendar), and also the Haab (civil calendar). Of these, just the Haab has a direct relationship to the length of the year.
A usual Mayan day looks choose this: 184.108.40.206.6, 3 Cimi 4 Zotz.
|220.127.116.11.6 is the long Count date.|
|3 Cimi is the Tzolkin date.|
|4 Zotz is the Haab date.|
What is the long Count?
The long Count is yes, really a combined base-20/base-18 depiction of a number, representing the number of days since the begin of the Mayan era. It is therefore akin come the Julian day Number.
The straightforward unit is the kin (day), i m sorry is the last component of the lengthy Count. Walking from best to left the remaining contents are:
|uinal||(1 uinal = 20 kin = 20 days)|
|tun||(1 tun = 18 uinal = 360 job = approx. 1 year)|
|katun||(1 katun = 20 tun = 7,200 work = approx. 20 years)|
|baktun||(1 baktun = 20 katun = 144,000 days = approx. 394 years)|
|The kin, tun, and also katun space numbered from 0 come 19.|
|The uinal room numbered indigenous 0 to 17.|
|The baktun space numbered indigenous 1 come 13.|
Although they are not component of the long Count, the Mayas had names for bigger time spans. The adhering to names are periodically quoted, although they are not old Maya terms:
|1 pictun = 20 baktun = 2,880,000 days = approx. 7885 years|
|1 calabtun = 20 pictun = 57,600,000 days = approx. 158,000 years|
|1 kinchiltun = 20 calabtun = 1,152,000,000 work = approx. 3 million years|
|1 alautun = 20 kinchiltun = 23,040,000,000 days = approx. 63 million years|
The alautun is most likely the longest named period in any kind of calendar.
When walk the lengthy Count Start?
Logically, the first date in the long Count must be 0.0.0.0.0, however as the baktun (the very first component) are numbered from 1 come 13 quite than 0 come 12, this very first date is actually written 18.104.22.168.0.
The authorities disagree on what 22.214.171.124.0 synchronizes to in our calendar. I have actually come across three possible equivalences:
|126.96.36.199.0 = 8 Sep 3114 BC (Julian) = 13 Aug 3114 BC (Gregorian)|
|188.8.131.52.0 = 6 Sep 3114 BC (Julian) = 11 Aug 3114 BC (Gregorian)|
|184.108.40.206.0 = 11 Nov 3374 BC (Julian) = 15 Oct 3374 BC (Gregorian)|
Assuming one of the an initial two equivalences, the lengthy Count will certainly again reach 220.127.116.11.0 ~ above 21 or 23 December ad 2012 - a not too far-off future.
The day 18.104.22.168.0 may have actually been the Mayas’ idea that the date of the creation of the world.
The diagram in ~ left reflects the work symbols, in the same order as the table above.
As the named week is 20 days and also the smallest long Count number is 20 days, there is synchrony between the two; if, for example, the last digit of today’s long Count is 0, today must be Ahau; if it is 6, it must be Cimi. Since the numbered and also the named week were both "weeks," each of your name/number readjust daily; therefore, the job after 3 Cimi is no 4 Cimi, however 4 Manik, and the work after that, 5 Lamat. The next time Cimi roll around, 20 days later, it will be 10 Cimi instead of 3 Cimi. The following 3 Cimi will not occur until 260 (or 13 x 20) days have passed. This 260-day cycle additionally had good-luck or bad-luck associations connected with each day, and also for this reason, it became known together the "divinatory year."
The "years" of the Tzolkin calendar room not counted.
What is the Haab?
The Haab was the polite calendar of the Mayas. It had 18 "months" that 20 days each, complied with by 5 extra days, recognized as Uayeb. This gives a year size of 365 days.
The names of the month were:
|1. Pop||7. Yaxkin||13. Mac|
|2. Uo||8. Mol||14. Kankin|
|3. Zip||9. Chen||15. Muan|
|4. Zotz||10. Yax||16. Pax|
|5. Tzec||11. Zac||17. Kayab|
|6. Xul||12. Ceh||18. Cumku|
In contrast to the Tzolkin dates, the Haab month names adjusted every 20 days rather of daily; therefore the day after 4 Zotz would certainly be 5 Zotz, adhered to by 6 Zotz ... Up to 19 Zotz, which is adhered to by 0 Tzec.
The work of the month were numbered from 0 come 19. This use of a 0th work of the month in a civil calendar is distinct to the Maya system; the is believed that the Mayas discovered the number zero, and the offers to i m sorry it can be put, centuries prior to it was uncovered in Europe or Asia.
The Uayeb days gained a an extremely derogatory reputation for bad luck; known as "days there is no names" or "days there is no souls," and also were observed together days the prayer and mourning. Fires were extinguished and also the population refrained indigenous eating warm food. Anyone born on those days to be "doomed come a miserable life."
The years of the Haab calendar room not counted.
The length of the Tzolkin year to be 260 days and also the length of the Haab year to be 365 days. The smallest number that deserve to be divided evenly by 260 and 365 is 18,980, or 365×52; this was well-known as the Calendar Round. If a job is, because that example, "4 Ahau 8 Cumku," the next day falling on "4 Ahau 8 Cumku" would certainly be 18,980 days or about 52 year later. Amongst the Aztec, the finish of a Calendar Round to be a time that public scare as it was believed the world might be comes to one end. When the Pleaides overcome the horizon ~ above 4 Ahau 8 Cumku, they knew the civilization had been granted another 52-year extension.
Did the Mayas Think a Year to be 365 Days?
Although there were just 365 work in the Haab year, the Mayas were mindful that a year is slightly longer than 365 days, and also in fact, plenty of of the month-names are linked with the seasons; Yaxkin, because that example, means "new or solid sun" and, at the beginning of the lengthy Count, 1 Yaxkin to be the work after the winter solstice, when the sun starts come shine because that a longer period of time and greater in the sky. As soon as the lengthy Count was put right into motion, that was started at 22.214.171.124.0, and also 0 Yaxkin coincided with Midwinter Day, as it did in ~ 126.96.36.199.0 ago in 3114 B.C.E. The accessible evidence indicates that the Mayas estimated that a 365-day year precessed v all the seasons twice in 188.8.131.52.0 or 1,101,600 days.
We can thus derive a value for the Mayan calculation of the year by dividing 1,101,600 through 365, individually 2, and taking that number and also dividing 1,101,600 by the result, which gives us response of 365.242036 days, i beg your pardon is slightly much more accurate 보다 the 365.2425 work of the Gregorian calendar.

(This evident accuracy could, however, it is in a an easy coincidence. The Mayas estimated that a 365-day year precessed with all the seasons twice in 184.108.40.206.0 days. These numbers are only accurate come 2-3 digits. Intend the 220.127.116.11.0 days had corresponded to 2.001 cycles quite than 2 cycles that the 365-day year, would certainly the Mayas have noticed?)
In ancient times, the Mayans had actually a heritage of a 360-day year. Yet by the fourth century B.C.E. They take it a different technique than either Europeans or Asians. They kept three different calendars at the very same time. In one of them, they separated a 365-day year right into eighteen 20-day months followed by a five-day period that was part of no month. The five-day duration was considered to be unlucky.
