The calendar cycle
For genuine astronomers,the calendar cycle begins on Mar 1st of one
year and ends 4 cycles later on February 29th having completed the required proportion of full rotations to the nearest orbital circuit which translates into the unused fact that the Earth turns 365 1/4 times per year. The Western calendar is so spectacular by virtue that its development relied on two major orbital events - the flooding of the Nile on a particular day and orbital point and the coincident appearance of Sirius from behind the glare of the central Sun ,in a way imitating what can be seen presently as Venus remains the only point of light left before the rotating Earth enters full solar radiation each day . There is something so amazingly fresh about the Egyptian description and a sense of pride behind it in that a few thousand years later,the development of the AM/PM system in tandem with the Lat/Long system grew out of those astronomical observations and terrestrial effects - "on account of the precession of the rising of Sirius by one day in the course of 4 years.. therefore it shall be, that the year of 360 days and the 5 days added to their end, so one day as feast of Benevolent Gods [the pharaoh and family] be from this day after every 4 years added to the 5 epagomenae before the New Year" Canopus decree,Egypt Now we have NASA trying to sound rational with Dec 21st nearing while the same organization insists there are 1465 rotations in 4 orbital circuits - "The Earth spins on its axis about 366 and 1/4 times each year, but there are only 365 and 1/4 days per year. " http://imagine.gsfc.nasa.gov/docs/as...rs/970714.html The end of the world indeed !,if there were sane people they could tell you when the end of the year is by counting the number of rotations/days across 4 annual cycles of the Earth.How it came to be that our astronomical ancestors could work out the references for annual traits and keep the daily cycles fixed to the orbital points of the solstices and equinoxes now stands in contrast to this era's inability to keep rotations and 24 hour days in step would look like the end of the world for any intelligent person and indeed it may very well be for there is nothing lower on the intellectual scale. I don't want people to be ashamed,I wish them to act like responsible people and that means some of the most public and renowned organizations in the world. |

The calendar cycle
The Long Count ends on December 21, 2012.
So, remember to adjust your calendars. From now on, a new calendar round will begin on every 4 Ahau 3 Yax, once in 52 years, during the new Baktun, instead of when 4 Ahau 8 Cumhu rolls around the way it used to be! John Savard |

... For genuine astronomers,the calendar cycle begins on Mar 1st of one year and ends 4 cycles later on February 29th Please explain what significance Mar 1st has to an astronomer. Surely the dates of the solstices and equinoxes are more significant? The choice of Feb 29th for the leap year day is completely arbitrary (certainly as far as astronomy is concerned). |

Surely the dates of the solstices and equinoxes are more significant? The beginning of a full cycle which contains the proportions of days/ rotations to years/annual cycles in keeping rotations fixed to annual points and visa versa is arbitrary,the Egyptians started their year using the annual appearance of Sirius which happened to coincide in their era with the Nile flooding whereas Western conventions begin Mar 1st and end 4 years later on Feb 29th.What is not arbitrary is the total 1461 days/rotations to 4 annual orbital circuits as this is a pure astronomical and technical matter.I don't even stop to consider January 1st but I am certain that Ra/Dec observers are locked into this convenient format where Feb 29th is almost anonymous technically so rather than go through an exposition on the Ra/Dec extensions,it is just easier to look at the original system,take note of the references and then rework the details into the Western system. The Egyptians have already supplied you with the reference which keep days fixed to an orbital event (Nile Flood) which was probably more important to them agriculturally than when the solstice of equinox happened.They realized that you cannot base the Nile flooding on a consecutive 365 day sequence but some very clever man noticed that the appearance of Sirius at dawn,in technical terms as the Earth's line of sight to Sirius due to its annual orbital motion takes the star a distance from the glare of the Sun,missed a day after every 4 years yet the Nile flooded on a specific date from its appearance.This is how they knew to add an extra day to keep days in sync - http://astroguyz.com/wp-content/uplo...of-Sirius..png Look,most of this is new in terms of comparing days/years with rotations/annual cycles and really it hasn't been done before.You do not need to stick pegs in the ground and wait for a star to return daily,the annual return of Sirius in simply a line of sight observation due to the orbital motion of the Earth and it doesn't matter where it makes an appearance,it only matters that it does so 365 days from any given year for 3 years but the next year it will not show up after 365 days but 366 days. The choice of Feb 29th for the leap year day is completely arbitrary (certainly as far as astronomy is concerned). February 29th is both a 24 hour AM/PM cycle and one rotation of the Earth with all its terrestrial effects,it also closes out the number of rotations/days for 4 orbital circuits but here we have this era which insists in trying to squeeze 1465 rotations into the same 4 year period thereby screwing up the explanation which ties the 24 hour AM/ PM system to the Lat/Long system on which clocks and civil timekeeping is based. What greater gift than the ability to use timekeeping properly and discovering its origins,what is arbitrary and what is beyond the control of humans and unfortunately too many assume that they are sorcerers and can dictate planetary motions and a choice of references hence they lose control of assertions. |

March 1st is significant to a calendrist, which relates it to astronomy since the calendar depends on the rotation and orbit of the Earth. March 1st is the day that the calendar year should begin, since then the length of the first eleven months is simply calculated and February reduces to a mere residuum.

Don't worry son,the star Sirius still does not return after 4 years of consecutive 365 days but an additional rotation is needed (Feb 29th) to close out 4 orbital circuits of the Earth hence the full proportions of rotations in 1461 to 4 which breaks down to the unused fact of 365 1/4 rotations to one circuit. The empirical inanity is all yours and especially as you are unaware that the format of 365 days/366 days is built on the motions of the Earth hence there are no choices involved - it is not even a 'solar' calendar as opposed to a lunar calendar but you would have to be an astronomer to work it out.So,when the observer looks at the brightest star in the celestial arena,they ignore any reference to its daily circumpolar return and consider only its annual appearance from behind the glare of the Sun as the orbital motion of the Earth brings it back into view,at one time its annual appearance coincided with the flood of the Nile hence our calendar is truly reflective of the motions of the Earth unlike your homocentric descriptions of a 'solar calendar'. In short,the calendar is one exciting mechanism which uses the actual motions and cycles of the Earth with one notable reference,Sirius in this case, as a basis of all timekeeping- when it is all put together it is as good a story as any out there and the basis for the 24 hour AM/PM cycle and Lat/Long system and although later Ra/Dec system a step too far as it tries to obliterate the original reference to Sirius in founding,it only requires astronomers to recognize the limitations. In all other walks of life you encounter experts who can discuss the ins and outs of things,I don't mean windbags who try to project superiority using trivia or rote learning that you can pick from any internet website,but true experts who are comfortable with technical and historical unknowns. I never encountered people who could even make sense of what the Egyptians wrote and why they were extremely proud of the additional day which was required to keep days in sync with the orbital points because empiricists are too fond of the Greek heritage to recognize anything further back in history for unlike the limitations of the homocentric Ra/Dec system,it appears the limitations extend to human history as well. "But that these feast days shall be celebrated in definite seasons for them to keep for ever, and after the plan of the heaven established on this day and that the case shall not occur, that all the Egyptian festivals, now celebrated in winter, shall not be celebrated some time or other in summer, on account of the precession of the rising of the Divine Sothis by one day in the course of 4 years, and other festivals celebrated in the summer, in this country, shall not be celebrated in winter, as has occasionally occurred in past times, therefore it shall be, that the year of 360 days and the 5 days added to their end, so one day as feast of Benevolent Gods [the pharaoh and family] be from this day after every 4 years added to the 5 epagomenae before the New Year, whereby all men shall learn, that what was a little defective in the order as regards the seasons and the year, as also the opinions which are contained in the rules of the learned on the heavenly orbits, are now corrected and improved" Canopus Decree I wish people would work towards making the system clear,from its beginnings to the later advancements which recognized the variations in the natural noon cycle and why they occur instead of trying to bury the system in a tangle of abbreviations and junk.Of course that takes talent. -- *(c) John Stockton, nr London, UK. * E-mail, see Home Page. * *Turnpike v6.05. *Website *http://www.merlyn.demon.co.uk/ - w.

I do not know what to make of any of you,the appearance of Sirius is an annual orbital event when the Earth moves around far enough to one side of the central Sun to bring the star into view - http://www.yorku.ca/ns1745b/fig2-sirius-helrise.gif The transformation of days/years into rotations/orbital circuits takes a little bit of work but there is nothing there that evokes this ignorance based on the idea that one 24 hour day does not keep in step with one rotation. I wish there was some decent person who knew enough to understand that this is actually important. |

You do understand, don't you, that several thousand other stars also reappear every day throughout the year when the Earth moves around far enough to one side of the central Sun to bring them into view, and that this event is not in any way limited to just Sirius? It is just a coincidence that the reappearance of Sirius happens to correspond to the annual flooding of the Nile. Other than that, it is of no importance whatsoever. \Paul A |
