The How and Why of the Mayan End Date in 2012
A.D. by John Major Jenkins
Why did the ancient Mayan or pre-Maya choose
December 21st, 2012 A.D., as the end of their
Long Count calendar? This article will cover
some recent research. Scholars have known for
decades that the 13-baktun cycle of the Mayan "Long
Count" system of timekeeping was set to
end precisely on a winter solstice, and that
this system was put in place some 2300 years
ago. This amazing fact - that ancient Mesoameri-
can skywatchers were able to pinpoint a winter
solstice far off into the future - has not
been dealt with by Mayanists. And why did they
choose the year 2012? One immediately gets
the impression that there is a very strange
mystery to be confronted here. I will be building
upon a clue to this mystery reported by epigrapher
Linda Schele in Maya Cosmos (1994). This article
is the natural culmination of the research
relating to the Mayan Long Count and the precession
of the equinoxes that I explored in my recent
book Tzolkin: Visionary Perspectives and Calendar
Studies (Borderlands Science and Research Foundation,
1994).
The Mayan Long Count
Just some basics to get us started. The Maya were adept skywatchers. Their
Classic Period is thought to have lasted from 200 A.D. to 900 A.D., but recent
archeological
findings are pushing back the dawn of Mayan civilization in Mesoamerica. Large
ruin sites indicating high culture with distinctly Mayan antecedents are being
found in the jungles of Guatemala dating back to before the common era. And
even before this, the Olmec civilization flourished and developed the sacred
count of 260 days known as the tzolkin. The early Maya adopted two different
time keeping systems, the "Short Count" and the Long Count. The Short
Count derives from combining the tzolkin cycle with the solar year and the
Venus cycle of 584 days. In this way, "short" periods of 13, 52 and
104 years are generated. Unfortunately, we won't have occasion to dwell on
the properties of the so-called Short Count system here. The Long Count system
is somewhat more abstract, yet is also related to certain astronomical cycles.
It is based upon nested cycles of days multiplied at each level by that key
Mayan number, twenty:
Number of Days / Term
1 / Kin (day)
20 / Uinal
360 / Tun
7200 / Katun
144000 / Baktun
Notice that the only exception to multiplying
by twenty is at the tun level, where the uinal
period is instead multiplied by 18 to make
the 360-day tun. The Maya employed this counting
system to track an unbroken sequence of days
from the time it was inaugurated. The Mayan
scholar Munro Edmonson believes that the Long
Count was put in place around 355 B.C. This
may be so, but the oldest Long Count date as
yet found corresponds to 32 B.C. We find Long
Count dates in the archeological record beginning
with the baktun place value and separated by
dots. For example: 6.19.19.0.0 equals 6 baktuns,
19 katuns, 19 tuns, 0 uinals and 0 days. Each
baktun has 144000 days, each katun has 7200
days, and so on. If we add up all the values
we find that 6.19.19.0.0 indicates a total
of 1007640 days have elapsed since the Zero
Date of 0.0.0.0.0. The much discussed 13-baktun
cycle is completed 1872000 days (13 baktuns)
after 0.0.0.0.0. This period of time is the
so called Mayan "Great Cycle" of
the Long Count and equals 5125.36 years.
But how are we to relate this to a time frame
we can understand? How does this Long Count
relate to our Gregorian calendar? This problem
of correlating Mayan time with "western" time
has occupied Mayan scholars since the beginning.
The standard question to answer became: what
does 0.0.0.0.0 (the Long Count "beginning" point)
equal in the Gregorian calendar? When this
question is answered, archeological inscriptions
can be put into their proper historical context
and the end date of the 13-baktun cycle can
be calculated. After years of considering data
from varied fields such as astronomy, ethnography,
archeology and iconography, J. Eric S. Thompson
determined that 0.0.0.0.0 correponded to the
Julian date 584283, which equals August 11th,
3114 B.C. in our Gregorian calendar. This means
that the end date of 13.0.0.0.0, some 5125
years later, is December 21st, 2012 A.D.1
The relationship between the Long Count and
Short Count has always been internally consistent
(both were tracked alongside each other in
an unbroken sequence since their conception).
Now it is very interesting to note that an
aspect of the "Short Count", namely,
the sacred tzolkin count of 260 days, is still
being followed in the highlands of Guatemala.
As the Mayan scholar Munro Edmonson shows in
The Book of the Year, this last surviving flicker
of a calendar tradition some 3000 years old
supports the Thompson correlation of 584283.
Edmonson also states that the Long Count was
begun by the Maya or pre-Maya around 355 B.C.,
but there is reason to believe that the Long
Count system was being perfected for at least
200 years prior to that date.
The point of interest for these early astronomers
seems to have been the projected end date in
2012 A.D., rather than the beginning date in
3114 B.C. Having determined the end date in
2012 (for reasons we will come to shortly),
and calling it 13.0.0.0.0, they thus proclaimed
themselves to be living in the 6th baktun of
the Great Cycle. The later Maya certainly attributed
much mythological significance to the beginning
date, relating it to the birth of their deities,
but it now seems certain that the placement
of the Long Count hinges upon its calculated
end point. Why did early Mesoamerican skywatchers
pick a date some 2300 years into the future
and, in fact, how did they pinpoint an accurate
winter solstice? With all these considerations
one begins to suspect that, for some reason,
the ancient New World astronomers were tracking
precession.
The Precession
The precession of the equinoxes, also known
as the Platonic Year, is caused by the slow
wobbling of the earth's polar axis. Right now
this axis roughly points to Polaris, the "Pole
Star," but this changes slowly over long
periods of time. The earth's wobble causes
the position of the seasonal quarters to slowly
precess against the background of stars. For
example, right now, the winter solstice position
is in the constellation of Sagittarius. But
2000 years ago it was in Capricorn. Since then,
it has precessed backward almost one full sign.
It is generally thought that the Greek astronomer
Hipparchus was the first to discover precession
around 128 B.C. Yet scholarship indicates that
more ancient Old World cultures such as the
Egyptians (see Schwaller de Lubicz's book Sacred
Science) and Babylonians also knew about the
precession.
I have concluded that even cultures with simple
horizon astronomy and oral records passed down
for a hundred years or so, would notice the
slow shifting of the heavens. For example,
imagine that you lived in an environment suited
for accurately demarcated horizon astronomy.
Even if this wasn't the case, you might erect
monoliths to sight the horizon position of,
most likely, the dawning winter solstice sun.
This position in relation to background stars
could be accurately preserved in oral verse
or wisdom teachings, to be passed down for
centuries. Since precession will change this
position at the rate of 1 degree every 72 years,
within the relatively short time of 100 years
or so, a noticeable change will have occurred.
The point of this is simple. To early cultures
attuned to the subtle movements of the sky,
precession would not have been hard to notice.2
The Maya are not generally credited with knowing
about the precession of the equinoxes. But
considering everything else we know about the
amazing sophistication of Mesoamerican astronomy,
can we realistically continue to deny them
this? Many of the as yet undeciphered hieroglyphs
may ultimately describe precessional myths.
Furthermore, as I show in my book Tzolkin:
Visionary Perspectives and Calendar Studies,
the Long Count is perfectly suited for predicting
future seasonal quarters, indefinitely, and
precession is automatically accounted for.
Some of the most incredible aspects of Mayan
cosmo-conception are just now being discovered.
As was the case with the state of Egyptology
in the 1870's, we still have a lot to learn.
In addition, Mayanists like Gordon Brotherston
(The Book of the Fourth World) consider precessional
knowledge among Mesoamerican cultures to be
more than likely.
The Sacred Tree
We are still trying to answer these questions:
What is so important about the winter solstice
of 2012 and, exactly how were calculations
made so accurately, considering that precession
should make them exceedingly difficult?
If we make a standard horoscope chart for
December 21st, 2012 A.D., nothing very unusual
appears. In this way I was led astray in my
search until Linda Schele provided a clue in
the recent book Maya Cosmos. Probably the most
exciting breakthrough in this book is her identification
of the astronomical meaning of the Mayan Sacred
Tree. Drawing from an impressive amount of
iconographic evidence, and generously sharing
the process by which she arrived at her discovery,
the Sacred Tree is found to be none other than
the crossing point of the ecliptic with the
band of the Milky Way. Indeed, the Milky Way
seems to have played an important role in Mayan
imagery. For example, an incised bone from
8th century Tikal depicts a long sinking canoe
containing various deities. This is a picture
of the night sky and the canoe is the Milky
Way, sinking below the horizon as the night
progresses, and carrying with it deities representing
the nearby constellations. The incredible Mayan
site of Palenque is filled with Sacred Tree
motifs and references to astronomical events.
In their book Forest of Kings, Schele and Freidel
suggested that the Sacred Tree referred to
the ecliptic. Apparently that was only part
of the picture, for the Sacred Tree that Pacal
ascends in death is more than just the ecliptic,
it is the sacred doorway to the underworld.
The crossing point of Milky Way and ecliptic
is this doorway and represents the sacred source
and origin. In the following diagram of the
well known sarcophagus carving, notice that
the Milky Way tree serves as an extension of
Pacal's umbilicus. The umbilicus is a human
being's entrance into life, and entrance into
death as well:
Diagram 1: Pacal and the Sacred Tree.
We may also remember at this point that the
tzolkin calendar is said to spring from the
Sacred Tree. The Sacred Tree is, in fact, at
the center of the entire corpus of Mayan Creation
Myths. We should definitely explore the nature
of this astronomical feature.
The first question that came up for me was
as follows. Since Lord (Ahau) Pacal is, by
way of divine kingship, equated with the sun,
and he is portrayed "entering" the
Sacred Tree on his famous sarcophagus lid,
on what day does the sun come around to conjunct
the crossing point of ecliptic and Milky Way?
This would be an important date. In the pre-dawn
skies of this date, the Milky Way would be
seen to arch overhead from the region of Polaris
(Heart of Sky) and would point right at where
the sun rises. This (and the corollary date
6 months later) is the only date when the Sun/Lord
could jump from the ecliptic track and travel
the Milky Way up and around the vault of heaven
to the region of Polaris, there to enter the "Heart
of Sky." It should be mentioned that 1300
years ago, during the zenith of Palenque's
glory, Polaris was much less an exact "Pole
Star" than it is now. Schele demonstrates
that it wasn't a Pole Star that the Maya mythologized
in this regard, it was the unmarked polar "dark
region" symbolizing death and the underworld
around which everything was observed to revolve.
Life revolves around death - a characteristically
Mayan belief. The dates on which the sun conjuncts
the "Sacred Tree" are thus very important.
These dates will change with precession. Schele
doesn't pursue this line of reasoning, however,
and doesn't even mention that these dates might
be significant. If we go back to 755 A.D.,
we find that the sun conjuncts the Sacred Tree
on December 3rd. I should point out here that
the Milky Way is a wide band, and perhaps a
10-day range of dates should be considered.
To start with, however, I use the exact center
of the Milky Way band that one finds on star
charts, known as the "Galactic Equator" (not
to be confused with Galactic Center). Where
the Galactic Equator crosses the ecliptic in
Sagittarius just happens to be where the dark
rift in the Milky Way begins. This is a dark
bifurcation in the Milky Way caused by interstellar
dust clouds. To observers on earth, it appears
as a dark road which begins near the ecliptic
and stretches along the Milky Way up towards
Polaris. The Maya today are quite aware of
this feature; the Quich» Maya call it
xibalba be (the "road to Xibalba")
and the Chorti Maya call it the "camino
de Santiago". In Dennis Tedlock's translation
of the Popol Vuh, we find that the ancient
Maya called it the "Black Road".
The Hero Twins Hunahpu and Xbalanque must journey
down this road to battle the Lords of Xibalba.
(Tedlock 334, 35. Furthermore, what Schele
has identified as the Sacred Tree was known
to the ancient Quich» simply as "Crossroads."
This celestial feature was not marginal in
ancient Mayan thought and is still rec- ognized
even today. In terms of how this feature was
mythologized, it seems that when a planet,
the sun, or the moon entered the dark cleft
of the Milky Way in Sagittarius (which happens
to be the exact center of the Milky Way, the
Galactic Equator), entrance to the underworld
road was possible, which could then take the
journeyer up to the Heart of Sky. Shamanic
vision rites were probably involved in this
scenario. In the Yucatan, underground caves
were ritual places used by shaman to journey
to the underworld. Schele explains that "Mayan
mythology identifies the Road to Xibalba as
going through a cave" (Forest of Kings,
209). Here we have a metaphorical reference
to the "dark rift" in the Milky Way
by way of its terrestrial counterpart, a syncretism
between earth and sky which is characteristic
of Mayan thinking. Above all, what is becoming
apparent from the corpus of Mayan Creation
Myths is that creation seems to have taken
place at a celestial crossroads - the crossing
point of ecliptic and Milky Way.
To clarify this ever growing picture, we should
stop here and plot out some charts. In addition
to the detailed star maps from Norton's 2000.0
Star Atlas which allowed me to pinpoint the
crossing point of Galactic Equator and ecliptic,
I use EZCosmos to plot these positions3. What
I found answers the question of why the Maya
chose the winter solstice of 2012, a problem
seemingly avoided by astronomers and Mayanists
alike. While it is true that the sun conjuncts
the Sacred Tree on December 3rd in the year
755 A.D., over the centuries precession has
caused the conjunction date to approach the
winter solstice. So, how close are we to perfect
conjunction today? Exactly when might we expect
the winter solstice sun to conjunct the crossing
point of Galactic Equator and ecliptic - the
Mayan Sacred Tree? Any astronomer will tell
you that, presently, the Milky Way crosses
the ecliptic through the constellation of Sagittarius
and this area is rich in nebulae and high density
objects. In fact, where the Milky Way crosses
the ecliptic in Sagittarius also happens to
be the direction of the Galactic Center.
