Mayan calendar.

Overview

Chac is a complete, accurate Maya calendar application. It can find Maya calendar dates based on today's date, any date, a Long Count, Tzolk'in, Haab', Calendar Round, Julian day number, distance number, long reckoning , seatings in the cycle of God K, and convert between the Julian and Gregorian calendars. Chac can find the next heliacal or cosmical rising or setting of Venus and the visibility of the current inscription or date.

You can use a large range of correlation constants, any one of the six possible moon numbers, astronomical or historical dating, any of the four Year Bearer systems and appearance of the new moon or the disappearance of the waning moon. Chac can display a Long Count with head or symbolic glyphs. Chac draws the results as a complete Maya calendar inscription.

An inscription with its preferences can be saved in Chac’s file format or it can be saved as graphics in TIFF, PDF, JPG, PNG, JP2, or BMP formats. An inscription can also be copied to the clipboard where it will be posted as PDF and TIFF.

What's new in Chac

Version 2.8.1:
  • I fixed a bug that caused the skull and crossed bones icon not to be displayed when the user uses a correlation constant other than the GMT

Actually, they did not predict the world would end on that day. I've read that they predicted that the end would begin on that day. Moreover, they predicted that we would be undone by our technology. Given Russian bots, hacking, and who knows what, and the world chaos that's ensuing, maybe they were on the money.

The image of the priest offering a victim's heart is too unsettling and unnecessary.

Virgeist, I don't know how serious you are concerning your comment. Perhaps you are simply being sarcastic. It is difficult to tell, being as you haven't used any smilies. Whatever the case may be, allow me to suggest that you take the time to read the three-part series entitled "2012: New Age Deception and Psychobabble". It is a matter-of-fact, sane examination of the 2012 hype. You can read it -- for free -- at the following URL: http://www.endtimeprophecy.net/Articles/2012bab1.html ENJOY!

Virgeist, just curious . . . How do you differentiate between that which is truly "religious crap" and that which is non-religious crap. Or do you consider anything -- and all things -- which has to do with religion and spiritual things as being "crap"? As a lifelong Christian, while even I recognize that there is a lot of "crap" going on in modern religion -- Christian and otherwise -- there is also a lot of truth to be found as well, if one is a wise, diligent seeker of the same; although it won't be found in the 2012 Mayan long calendar nonsense. :)

@WordWeaver Since you asked, my position on religion is as follows. From where I stand as an outsider, I don't think we can honestly say that one religion is more legitimate an another, since all beliefs are based on the same amount of empirical evidence — that is to say, none at all. This is why I am perplexed when you label the Mayan calendar stuff as nonsense while you seem certain of the validity of your own beliefs. Ultimately, the only quantifiable difference between the major religions (once again, from my perspective as an agnostic) is time, social acceptance and the number of followers. Despite this admittedly cynical view, I am not opposed to the idea of a god in itself. It's just that it seems very unlikely that a god would be anying like what is described in the holy texts of major religions. I don't rule out the deist concept of a god that is merely energy, or the Spinoza approach that consists in considering the whole universe as god itself. That said, I believe that organised religion is very useful, as it gives hope to people who would otherwise wither and die. Not everyone can take the red pill and face reality happily, so to speak. Religion serves a useful purpose as a tool to encourage positive behaviour and as psychological support, so I believe it should maintain a place in our society (assuming scientific progress is not slowed or halted as a result). Anyway, I don't really want to engage in a heated debate on the matter, as this would be a disservice to the Chac developer to drive potential users away with controversy.

Don't worry Virgeist; I am not the least bit interested in debating with you. I was merely curious regarding your previous remarks. Obviously, I don't agree with all of your points, but that is for another time and place. However, let me mention -- or perhaps clarify -- that as I point out in the series "2012: New Age Deception and Psychobabble", I agree with the Chac developer's opinion that a lot of unfounded, unsupported nonsense has in fact been attached to the Mayan Calendar, and the year 2012, which even modern-day Mayans do not agree with. I mention this point in the series. The people who are profiting most from the 2012 hype are movie producers and book authors, because there are always naive, gullible souls who are willing to take the bait. Should we expect any less of them?

I am a great fan of both Chac and MacMaya. My Mac died and I had to downgrade to the more affordable pc world. I would be thrilled to have a pc version or iphone app for both Chac and MacMaya.

Chac replaces MacMaya so no more MacMaya. IPhone and iPad - maybe since apps for these are developed with Objective C/Cocoa with some additional classes. Windows - NEVER, NEVER. I would have to buy a PC, learn the .net framework, and C# or C++. This would be a whole lot of work for a free program. Also why should I work on a crappy knock-off (windows) when I can have the real thing. Get a Mac.

I just got this app mailed.... ad I was watching some others calendars... I'm pretty confused, because mr. Ian Lungold rom www.mayanmajix.com uses Calleman's Book for his speeches, and this one ends in 28. October 2011, not 2012.... And 2nd, I was using the apple maya calender widget. http://www.apple.com/downloads/dashboard/information/mayacalendar.html And a second calendar from the learning lab of mayanmajix: http://www.xzone.com.au/tzolkin/getcalendar.php And those both were showing me the same date today, Example, in both was 3 Etz'nab today. And this Chac Calendar is the onlyone showing 9 Eb being the Day today.... I still haven't find which is right, but till now, is 2 softwares(apple widget and xzone) against 1 (chac) If you find out anything about which one is right, please let me know by commenting back :)

The farthest right menu in a Mac OS X application is a Help menu. The second item is entitled "Chac Help". All of this is explained in this help document. More discussion of the writings of Jose Arguelles, Ian Lungold, Carl Callemans, Terrence McKena, etc. can be found in the talk page of the Wikipedia article about the Mesoamerican Long count Calendar here: http://en.wikipedia.org/wiki/Talk:Mesoamerican_Long_Count_calendar Reading this will explain why their theories are never allowed in the wiki pages about the Maya calendar. The bottom line is that they are new age spiritualists who have made up bizarre incorrect theories about the calendar and their writings are dis information. Chac agrees with the Dashboard widgit but has lot more information.

Chac, http://www.xzone.com.au/tzolkin/getcalendar.php and the dashboard widget all agree so I don't know what you're talking about. the online calculator is an astrology page and it only can calculate today's Tzolk'in so it's fairly worthless. The widget can only calculate today's Long Count and calendar round so it's quite limited in what it can do as well.

i believe the Maya calendar ends in 2012 with the end of the world. I just saw something on the History Channel about it.

No, the Maya calendar doesn't end in 2012. This is explained in the help book for this application. You can read it by going to the help menu and selecting the second item: Chac Help. There are actually two of those shows about the "Mayan Doomsday Prophesy" on the History Channel. They probably have set a dubious record by condensing more disinformation into one show than any other TV show in the history of television. These shows are entertainment, amusing fiction but not science.
