We have a lot to learn from the ancient Mexicans about time – its measurement, its management and its meaning. In the modern world we tend to relate the passing of time to movement along a straight line (look at history timelines in our classrooms!) and assume automatically that ‘latest is best’ - a computer is instantly ‘out of date’ the day after we’ve bought it. We’re only now beginning to rediscover the ‘wisdom of the ancients’ and to realise how arrogant we’ve been in ‘writing off’ - for centuries – their sophisticated knowledge of time, mathematics, astronomy, geometry and music, all of which relate to each other through rhythm patterns at the very heart of our universe.

Hundreds, if not thousands, of years before us, the Mesoamericans had discovered zero, measured leap years to 4 decimal points of accuracy, allowed for the influence on us not only of the sun but also of the moon and Venus (the 3 brightest bodies in the sky), clocked the motion of Venus to an accuracy of better than two hours in five centuries, played different notes simultaneously in musical performances, and even very likely calculated the Precession of the Equinoxes – a period of 26,000 years.

Counting in 20s – presumably because we have 20 fingers and toes – they developed complex time rounds that, like wheels, are far more natural in design than our modern Western European calendar with its odd mix of 30-, 31- and 28-day months.

There’s no doubt that, as far as calendars go, the Mesoamericans could literally run rings round us ...!
The Aztec calendar features strongly in our school programmes. Good friends Steve and Michelle (and pupils) at Little Green Junior School, Croxley Green, Herts., produced this beautiful wall hanging illustrating the Aztec day signs (well, 19 of them anyway...)

Whilst in the snap above we took of the daysigns at one of our all-time favourite schools, Redriff Primary, Rotherhithe, we noticed they’d been a bit TOO keen and ended up with 21!

The Aztec Sunstone/Calendar Stone continues to fascinate young and old alike. We recently snapped a group of Year 6 boys at St. Nicolas School in Cranleigh, Surrey, who spontaneously gave up their lunch break to study our large Sunstone model before we packed it away after a workshop. We were just sorry that the copy in their classroom was VERY ‘cheap-and-nasty’: follow the link below...

I have a doubt regarding the correlation dates for the Aztec Calendar.
It’s widely accepted that the fall of Tenochtitlan was in August 13, 1521 - which corresponds to the Julian date number 2276828 (at 12AM).
This date is correlated to the aztec date 2 Xocotlhuetzi 1 Coatl.
On the other hand, another well knowed date is refered: the entrance of Cortez in the city, in November 8, 1519.
This date corresponds to the Julian day 2276184 (12 AM).
It’s refered to the aztec date 8 Ehecatl 9 Quecholli of the year 1 Acatl.
The problem is that if we take the first correspondence, we will get for the second julian day number the date 7 Cipactli, 8 Quecholli.
It’s one day of delay.
If we take the second date as reference, the first will give us one day after the citation.
There’s always one day of difference - I think I’m not mistaken.
All the sites that do the calculations based on Alfonso Caso correlation, and in the first correlation date I’ve mentioned, cleary show the discrespancy in the calculations.
Can you please tell me if I’m missing something here?
Mexicolore replies: Thanks, Rui. I’m afraid our level of expertise doesn’t run to answering this for you. What we DO know is that this issue of correlation is a veritable nightmare! An excellent website that tries to make sense of the correlations problem is given above, recently added (2016). Recommended!

The Aztec day Xochitl was zero kin just like the Mayan day Ahau. The Aztec day Mazatl was 7 kin just like the Mayan day Manik. The Aztec day Acatl was kin 13 just like Ben. But Xochital was moved 13 days earlier on Mazatl so that 1Acatl was 1Ahau but 1Acatl becomes moved 13 days earlier to the day that was 1Mazatl and 1 Manik. In 1518AD this is 0Pop the Mayan year bearer 1Manik, no longer Aztec 1Mazatl, but now year bearer 1Xochitl on 0Pop. So for the year to be CeAcatl (1Reed) becaus ethe day is 1Acatl the Aztec new year has to be regarded as 13 days later as 1Ahau 13Pop. Thus 1Acatl formerly 1 Ben will now always be 1Ahau, and the Aztec 365-day Xiuh-Pohualli like the Mayan 365-day haab will always fall on 13Pop. I prefer the Genesis correlation of G.Aug 12 in 3114bc and so Egyptian Thoth 1 is always Pop 17 (not 18) and this means Aztec new year on Pop 13 is always Epagum 2. The G.Aug 11 epoch makes Aztec new year and Pop 13 as Epagum 1. There are correlations that debate the 360-day calendar Long Count as falling on 2,7,12,17 while others on 3,8,13,18. The Aztec new year is obviously then exactly 260 days before Cortez whether 1Acatl is Thurs Apr 21 or Good Friday Apr 22, thus debating whether the new year 1Acatl in 1518ad is July 22 or 23. I would very much like to know the Aztec equivalent to Pop and Uo etc.

The date 2 rabbit was also a symbol of drunkeness, legend says a rabbit scratching out the center of a maguey agave plant drank the fermented licor and became intoxicated, And anyone born under the sign of 2 rabbit was destined to become an alcoholic.
Alcoholism in Aztec times was severly punished.

Please give me the meaning or where I can go to get information on the New year 2013, year of the Calli
Mexicolore replies: 2013, as a year in our ‘solar’ calendar, would be named, in the equivalent Aztec xihuitl Ce-Calli, or ‘1-House’. (2012 is ‘13-Flint’ and 2014 will be ‘2-Rabbit’, followed by ‘3-Reed’ in 2015). House-Rabbit-Reed-Flint was the cycle of four year signs which, accompanied by a number from 1-13, made up the very important period of 4x13=52 years, something like the Aztec equivalent of our ‘century’. You can’t read too much into one single factor such as the ‘name’ of next year (Calli or House): for ‘meaning’ you need to look at a whole range of extra elements, combining solar and lunar calendars.

It is important to remember that the Spaniards and literate Aztecs who chronicled the ancient civilization wrote about people in the cities. They neglected to document village life and religious traditions in smaller communities. The result is that we know little about the people who lived at the edges of the Aztec empire and even less about their gods and rituals. However, Aztec villagers must have shared many features of their culture with people in the cities, and so we can assume that the gods worshiped in the rural areas must have been similar to those worshiped in urban centers.

When is the Aztec New Year? One might think that it was our December 21, given the significance of that date in 2012, but I’ve seen at Wikipedia that it’s claimed to be two different dates, both around the end of January, Xispas.com says the date is March 12, and at AztecCalendar.com I noticed that the Solar Year changed on October 6th, 2008 (which although seems to be a great site, I’m not now sure how much faith to place in it, since I’ve failed to notice any unnamed days of the Nemontemi which precede the new year). Since the Caso correlation works from the well-recorded date of the fall of Tenochtitlan ‘1-Coatl = August 12’ just when is it?
Mexicolore replies: This is always going to be a hard question to answer in any clear-cut way. Sahagún noted in the Florentine Codex that in the 16th century the Aztec year began on 2 February by our calendar. But remember for a start a) just how inaccurate the old Julian calendar from Europe was in those days and b) that there were even regional differences in pre-Hispanic Mexico concerning the calendar round. Traditionally (see the work of Paso y Troncoso and Seler, or look at the Codex Borbonicus) the Aztec agricultural year began with the festival of Izcalli, matching the European calendar in 1521 CE with the dates January 24 to February 12 (each festival was a 20-day ‘month’). But several scholars have shown that this starting point was not standardised even within the Basin of Mexico: Kirchhoff, for example, suggested back in 1950 that there were 13 different calendric systems in use simultaneously by 13 different ethnic groups in and around the Basin of Mexico! This meant that the year 1-Reed for the Aztecs would be 7-Reed for the Texcocanos, 3-Reed for the Matlatzinca, 12-Reed for the Colhua, etc. Correlating the calendars is a minefield...!

I have read aztecs gave special “magical” properties to numbers, and so the days in the calendar would be influenced by each number’s quality. E.g. number “one” being a good omen number. Is there a chance you can tell us more about number’s particular magical sense?
Mexicolore replies: Yes, you’re right, each number had its own significance. Very briefly, the numbers 3, 7, 10-13 were generally lucky, while 4, 5, 6, 8 and 9 brought bad luck. The number 2 linked to the daysign Rabbit was particularly unfortunate. 1 was considered neutral, though it was associated with (new) beginnings and in this sense was a positive number.

Were birthdays celebrated, and if so, how were birth years measured? I’ve seen codices denote days of birth using the dot-and-glyph method to pen names (which reflects xiuhpohualli method) but also dots used to show how old a child is (which I make the modern assumption this number is measured in solar/seasonal years - I see a conflict with my assumption).
Do we know or have a reasonable assumption as to whether those year-dots are based on 260 day cycles (xiuhpohualli) or 365 day cycles (tonalpohualli)?
I’m curious what confusion this may have created because someone claiming to be "42" (xiuhpohualli) would only be 30 years old by the customary solar year measure.
Mexicolore replies: We think your confusion stems from the fact that ages of children by reference to year dots are only (to our knowledge) found in the Codex Mendoza - written AFTER the Conquest. These ages are clearly written as ‘European’/solar/tonalpohualli years. All birth ‘day’ signs/names in pre-Hispanic codices refer to the ritual 260-day xiuhpohualli calendar round. As far as we know, yearly birthday celebrations, as we know them today, were not a part of Aztec life.
