An example of a tzolkin date could be "1 Imix"<BR/><BR/>The list of names had intercalated orientation (orient, nort, ponient, sout) so every "week" (5 days) started and ended with the same orientation... and every of the 260 designations of days informs elapsed days and orientation. They also divided the calendar in periods of 52 days (unique combinations of 13 numbers with 4 orientations)<BR/><BR/>This system its then based on the relation of two sets: the base 13 numbers and the 20 names. The consecutive asociation was done trought simple counting, making pairs... there were not needed any operations with positional notation.<BR/><BR/>All this counts (asociations) are cyclic... repetitive, but not identical because every repetition starts at a diferent point in the cycle. I think of them, like time units (for example [day:orientation] to name a "week") The name of the repetition its given by is starting day (for example "week" 1-nort) The relation of two sets with a difference in cardinality of 1 its very common in the maya "time units" (for example 5 days:4 orientations) and its called "movement efect" because the maya didnt have a word for "time", to talk about the elapsing of time they used words related to movement<BR/><BR/>The maya also used a calendar of 365 days we call haab (divided in 73 "weeks" of 5 days or 18 "months" of 20 days plus 1 week... of bad luck) The haab is an alternate form of the tzolkin that relates (trought consecutive asociation) the number of day (from 0 to 19) and name of the month. Examples of the names of the month are: Pop, Uo, Zip, Zotz, Tzec, Xul, Yaxkin, Mol, Chen, Yax, Zac, Ceb, Mac, Kankin, Muan... An example of a haab date could be "4 Ahau - 18 Pop". Therefore, the day 0 Pop was the maya new year, and the haab date (for example "1 Imix - 0 Pop") designed the name of the year. The tzolkin-haab dates gave the mayas 94,900 unique combinations (of 260 tzolkin dates with 365 days of haab months) to name his days.<BR/><BR/>Here comes the really interesting part... To measure longer periods of time, the maya keeped lists of dates "sampled" from the tzolkin-haab succession of days at some fixed interval. Doing a mathematical analysis of the numeric properties of this calendaric system, was found that some astronomical intervals produced lists of "sampled" dates sorted (as a whole or in part) in ascending, descending order or with a fixed marker. The astronomical intervals where aproximated because the mayas used only whole numbers.<BR/><BR/>For example here are some lists of "sampled" dates at fixed intervals (using for simplicity 1Imix-0Pop as origin, not the historical 4Ahau-8Cumhu)<BR/>365 days : 1Imix-0Pop, 2Cimi-0Pop, 3Chuen-0Pop, 4Cib-0Pop, 5Imix-0Pop, 6Cimi-0Pop, 7Chuen-0Pop, 8Cib-0Pop...<BR/> Here, obviously se fixed marker its the "0 Pop" or new year day<BR/>584 days : 13Chicchan, 12Muluc, 11Ben, 10Caban, 9Imix, 8Chicchan, 7Muluc, 6Ben, 5Caban, 4Imix, 3Chichan...<BR/> Aproximated Venus sinodic revolution<BR/>116 days : 13Caban, 12Ben, 11Muluc, 10Chicchan, 9Imix, 8Caban, 7Ben, 6Muluc, 5Chicchan, 4Imix, 3Caban...<BR/> Aproximated Mercury sinodic revolution<BR/>378 days : 2Cauac, 3Caban, 4Men, 5Ben, 6Chuen, 7Muluc, 8Manik, 9Chicchan, 10Akbal, 11Imix, 12Cauac...<BR/> Aproximated Saturn orbital sinodic period<BR/>780 days : 1Imix-10Zip, 1Imix-0Xul, 1Imix-10Mol, 1Imix-0Zac, 1Imix-10Mac, 1Imix-0Pax...<BR/> Aproximated maximun Mars oposition to Sun<BR/>399 days : 10Ahau, 6Cahuac, 2Etznab, 11Caban, 7Cib, 3Men, 12Ix, 8Ben, 4Eb, 13Chuen, 9Oc, 5Muluc...<BR/> Aproximated maximun Jupiter oposition to Sun (this succession its ordered in the names)<BR/><BR/>The mayas used what now we call "astronomical" days (that start/end on midday) in order to keep all the astronomic observations of one night on the same date. Divided the sky in sections, and for the record of some visible planet, used like reference point the presence of close deep space objects and changed sections and objects over time.<BR/><BR/>There is much more to this theory.... but i am late already, and dont have more time to write about it.alushehttp://www.astrored.org/mexiconoreply@blogger.comtag:blogger.com,1999:blog-7306557.post-887366939762950862007-09-20T18:48:00.000-07:002007-09-20T18:48:00.000-07:00I like many others find the end date, or end perio...I like many others find the end date, or end period of the mayan calendar fascinating. Given the emperical evidence of conditions on this planet now and in the immediate future, one truly does not have to be a rocket scientist to see major change on the horizon. There are over 6 billion people on the earth and they all want the same things out of life. Maybe the changes to come will be a birth process..very messy...but truly profound for mankind.AMGhttp://www.blogger.com/profile/16206767509148904897noreply@blogger.comtag:blogger.com,1999:blog-7306557.post-1156630916378778022006-08-26T15:21:00.000-07:002006-08-26T15:21:00.000-07:00Although I am an independent Baptist I find the Ma...Although I am an independent Baptist I find the Mayan Calendar very interesting. Many may argue, that like Nostradamus, the predictions are vague and could be applied to many times and events if the right spin is applied. However, I find it very peculiar that in a Katune about 2012 (the end of time for them) that the author says that for (not verbatim) "half will be blessed and half will be cursed and the judgement of God will follow" (i'm not sure exactly the quote please find it for me). Now if you examine revelation by John then you know that he predicts 7 years of prosperity and 7 years of destruction and death before the judgement of God. The first thing I thought of when I read the Katune was not half of the population... but half of the time.

Anyway, here's was wikipedia has to say:<BR/><BR/>"The turn of the great cycle is conjectured to have been of great significance to the Maya, but does not necessarily mark the end of the world. According to the Popol Vuh, a sacred book of the Maya, they were living in the fourth world. The Popol Vuh describes the first three worlds that the gods failed in making and the creation of the successful fourth world where men were placed. The Maya believed that the fourth world would end in catastrophe and the fifth and final world would be created that would signal the end of mankind.<BR/><BR/>The last creation ended on a long count of 13.0.0.0.0. Another 13.0.0.0.0 will occur on December 21, 2012, and it has been discussed in many New Age articles and books that this will be the end of this creation or something else entirely. However, the Maya abbreviated their long counts to just the last five vigisimal places. There were an infinitely larger number of units that were usually not shown. When the larger units were shown (notably on a monument from Coba), it is expressed as 13.13.13.13.13.13.13.0.0.0.0, where the larger units are obviously supposed to be 13s in all larger places. In this creation we are only approaching 0.0.0.0.0.0.13.0.0.0.0, and the larger places are no where near the 13s that would match the end of the last creation.<BR/><BR/>This is confirmed by a date from Palenque, which projects forward in time to 1.0.0.0.0.0, which would be in 4772. The Classic Period Maya obviously did not believe that the end of this age would occur in 2012. There will be a Baktun ending in 2012, a significant event being the end of a 400 year period, but not the end of the age."SQPY23http://www.blogger.com/profile/05844159283024883949noreply@blogger.com
