The 13-month, 28-day alternative has been in use on this planet for more than 6000 years. In prehistoric India and China, and throughout South America it was the standard time-keeping system. The Essenes, Egyptians, Polynesians, Maya, Inca, Lakota, and Cherokee used a 13-month, 28-day calendar. The Celtic knowledge of the Druids is based on the Tree Calendar, also a 13-month, 28-day calendar. Today many cultures are still using their traditional 13-month calendar system.
Calendar reform, properly calendrical reform, is any significant revision of a calendar system. The term sometimes is used, also, for a proposal to switch to a different calendar. The idea of calendar reform is not a new, crazy idea.
Please find below an excerpt from the history of calendar reform from the book Thirteen Moons in Motion by José and Lloydine Arguelles, the last advocates of calendar reform of our time:
THE PAST:
“The two most significant calendar reforms in history were the Julian calendar reform of 46-45 B.C., and its successor, the Gregorian, in A.D. 1582. Julius Caesar’s motives had everything to do with his personal ambition and the conversion of Rome from a republican to an imperial form of government. Julius Caesar’s calendar assured it to be the basis of imperial dominance. The course of the empire utilizing the Julian and later Gregorian calendar has prevailed as the dominant force now inseparable from the course of history itself. The 445-day “year of confusion” (46 B.C.), which attended Julius Caesar’s reform, was matched by the second significant reform, the Gregorian, in which ten days were “lost forever,” between October 5-14, 1582, so that the calendar could “catch up” with the sun.
“While European Catholic countries easily accepted the reform, Protestant countries begrudgingly acquiesced. Throughout the Americas, however, the Julian-Gregorian calendar was imposed as an instrument of power and symbol of dominance over the peoples the Europeans had conquered, including the high civilizations of the Maya, Inca, and Aztecs—all of whom happened to use, among other calendars, a Thirteen Moon/28-Day count. As with Julius Caesar, for Pope Gregory XIII the moment was politically ripe for a reform that would communicate itself as a means of expressing and extending power and control, but this time over the entire globe. As European dominance and control spread around the planet, even nations with their own established timing systems accepted, for the sake of “international policy,” the Gregorian (Julian) calendar system for measuring the solar year. And so Western dominance over every aspect of global life became absolutely assured.”
After the original time came the seeds and the planting. Then came the sword, and the forgetting. During the last four hundred years the Indigenous Peoples of the planet retreated deeper into the forest, the wilderness, the jungle. Wherever they went, they were followed by the machine and the twelve-month calendar of colonialism. Deprived of their own time, the Indigenous Peoples were forced into the false time of the machine.”
“On October 12, AD 1492 (Dreamspell 7 Earth of year 7 Storm), Christopher Columbus arrived in the “New World.” The hopes of the Maya, the Hopi, and all indigenous people, not only of the Americas, but of the entire planet were thoroughly shattered and destroyed. Genocide, enslavement, and colonization were the indigenous people’s reward. Never had the knowledge of a high civilization been so intentionally desecrated and destroyed as was that of the Maya.In one single act of conquest, humanity was deprived of the gift of the knowledge of time. By 1583 the Catholic Church installed its “reform” of time known as the Gregorian calendar. Simultaneous to the proclamation of the Gregorian calendar was the development of mechanized time, the basis of all machine technology. Instead of the 13:20 galactic frequency of time, the planet was bequeathed with the 12:60 (12-month year, 60-minute hours) frequency of machine technology.”

THE PRESENT
Calendar reform is NOT a new crazy idea
It is important for us to remember that during the first half of the 20th century, a vigorous and well organized calendar reform movement flourished. George Eastman of Eastman Kodak organized a great campaign on behalf of a particular 13-month, 28-day calendar, known as The International Fixed Calendar, a perpetual calendar (same every year) with 13 equal months of exactly 4 weeks (28 days) each, comprising 364 days, and with the final 365th day held not in any week or month, often known as a “Null Day” or “Zero Day,” so that the first day of the year is always the first day of the week, a Sunday.
A truly “KODAK Moment”
“In 1922, the League of Nations appointed a Committee of Inquiry to study the question of calendar reform. More than 130 (185) different proposals were submitted to the committee, but the Cotsworth Plan is the one outstanding proposal that meets the needs of business organizations such as the International Chamber of Commerce, the NY State Chamber of Commerce… and is fast gaining favor among business men. In fact, many concerns have already adopted a thirteen-month calendar for their records and are already getting some of the advantages of the proposed plan…”
The Campaign for the New Time of the New Millenium

It was following the stabilization of the World Thirteen Moon Calendar Change Peace Movement through the Foundation for the Law of Time, that a serious study was undertaken to incorporate the information regarding the earlier calendar reform movement into considerations of the current Thirteen Moon Calendar Change Peace Movement. From these efforts came the next stage of operations, the Campaign for the New Time, 2000-2004. It is now important to understand something of the history and nature of this earlier reform movement, because it lends even greater legitimacy and contextual seriousness to the efforts of the Movement to which the Foundation for the Law of Time is committed to pursue to the end.”

In 1996, the World Thirteen Moon Calendar Change Peace Movement was initiated by artist, author, and educator José Argüelles and his wife Lloydine Burris, in an effort to establish whether or not people of various cultures would respond to the call for replacing the Gregorian calendar with the Thirteen Moon calendar. Correcting for the irregular standard of the Gregorian Twelve-Month Calendar, the Thirteen Moon 28-Day Perpetual Calendar is an even standard of measure based on the female biological cycle.
To promote the cause of the Calendar Change, they convened:
- The First Planetary Congress of Biospheric Rights (1996, Brasilia, Brazil)
- The World Congress on the Law of Time (Tokyo, Japan, 1997); and the
- World Summit on Peace and Time (University for Peace, Costa Rica, 1999).
Since both the Vatican (1961) and the United Nations (1956) had already proposed a need for calendar reform, the 13 Moon Calendar Change Peace Plan called for planetary unification in the “new time” (13:28) on July 26, 1999.
In order to test the hypothesis of the Law of Time, that the human race was destroying its biosphere due to operating according to an error in time, and that only a shift in its experience of and perception of time would save it from such destruction, Jose and Lloydine took on the responsibility of organizing the World Thirteen Moon Calendar Change Peace Movement.
Beginning in Latin America, then spreading to Japan, Western Europe, Russia, and finally North America, a movement to change the everyday perception of time was established, instilling profound meaning behind the effort to reform the calendar.
The role of the World Thirteen Moon Calendar Change Peace Movement was particularly significant because it grounded on Earth an entire new knowledge base rooted in the advanced calendrical science devised by the ancient Maya civilization of MesoAmerica centuries ago. The modern, most simple and practical application and implementation of this mathematical system to reckon time is the 13-Moon, 28-day Calendar matrix. Even though the campaign did not achieved to change the calendar, this global movement is still present in more than 80 countries, and allowed a critical mass of human beings to consciously track the closing of the 5,125-year Great Cycle of History (3113BC-2012AD) , that was completed on December 21, 2012.

Why are we so blind about these KEY subjects of TIME and CALENDARS if these are the guiding principles of our EVOLUTION and CONSCIOUSNESS? What can be done about this?
THE FUTURE
The call for a NEW Macro-Organizing program for Society
We now understand that a calendar is a programming device for a society. Our beliefs, habits, and customs are governed by the calendar that we use. Throughout human history, calendars have been the primary instrument by which a society is regulated and controlled.
A calendar is like the operating system of your computer. You are usually unaware that you are using it until a glitch causes the system to get confused. A calendar should not create confusion due to its irregularity and irrationality.
It should be an operating system that is clear, simple, and perpetual, one that creates awareness of natural cycles of time.
“To change and replace the calendar with the thirteen moon standard is to return us to our original purpose, leading us back to pathways of natural health. According to the law of time, the damage already inflicted in the time humanity last hesitated and lost the chance to alter its timing frequency, 40 years ago, has been incalculable. The final opportunity to change the calendar and the timing frequency is now upon us. Because of this we must be very clear and unshakable in our understanding and determination to expose and eliminate the current civil calendar for once and for all.” ~ Jose Arguelles
The return to NEW Standard Unit of Measure
In the current world standard 12-month Gregorian calendar, the units of measure, months, are of unequal length. Perhaps it is the only measurement known to man that has unequal units of measure.Consider that today is Friday. Using the 12-month system, it is “Friday, July 22nd, 2016” One month later in this system, it will be “August 22nd” But what day of the week will it be?Because the months are irregular and do not have a whole number of weeks, WE DO NOT KNOW.When there is this disruption in the flow of consciousness, it is like a glitch in the operating system. It causes error and confusion. And this occurs every day for millions of people.Such a system is an idiotic basis of human thought. It is a time virus, and so it is a consciousness virus. The ramifications are incredible just as it is incredible that such a system of confusion is still in use. […]
“Of all the unexamined assumptions and criteria upon which we base and gauge our daily lives as human beings on planet Earth, by far the greatest and most profoundly unquestioned is the instrument and institution known as the Gregorian Calendar.”
