To the right is the Cakra constellation , defined as a cycle of years ; a hexagon.  In the hexagon the constellation Draco the dragon with it's tale ending in where on the procession the star Thuban is (Ruha is the head and ketu is the tale).  The constellation was laid over the meridian and local horizon forming a calendar that incorporated a geographic positional tool where the seasons would change with time as the precission of the equinox changed (the hexagon below does not change the seasons change not the Hexagon).  With this tool a meridian is conceptualized like the Stupa at Sanchi intercepting their prime meridian at 23.4795 degrees north of the ecliptic ( Sanchi is 23.4795 degrees north and the equator and ecliptic pole is 23.4393 in 2000 CE degrees from the celistial pole). The exact position of the celestial pole can then be calculated a zenith is formed and Nader from this the longitude and latitude can be calculated with the right ascension of heavenly bodies equaling 15 degrees an hour and two hours is a Zodiac house 30 degrees , two houses is 60 degrees then 72 orbits instead of years for one degree of precission ,  72 x 60 = 4320 orbits .  Below in the Hexagon (that is today finding the star Polaris as the celestial pole at the top of the hexagon , in past times the last part of the spring before the summer equinox  the celistial pole was above Polaris)  for four month Vishnu rides on the back of the dragon decribed by Manu the prophet of the Vedic flood acount, Manu decribes Vishnu as moving on the waters , reclining on Sesha the serpent of "infinity" , then spoke of an astronomy of the century's ( the presicion of the Equinox).   A Loka Has 4 month X 3  and 3 cubed is 27 Naksatras(  found on the Indus seals as the Unicorn ; one horn sanskrit; ekazRGga having but one horn , unicorn ; having but one peak the name of Vishnu) 
  Ketu the bright appearance , clearness ,    "rays of light"  RV. VS.AV   here ketu the dragon's tail or descending node considered in astron. as the 9th planet , this is an alignment of Druva the star "Polaris" and the triple stars of "Orion" today's 6th hour and the fixed Naksatra's that are the fall equinox of today "Leo" Purva Phalguna , the winter solstice "Sagittarius" Purva Ashada and today's spring equinox "Pisces" Revita.  Polaris and the star Thuban were used to form the cricle below with the hexagon being formed inside it starts with Polaris.  Polaris with it's highest , lowest and middle points  having been fixed in ancient times because of the difficulty in finding the celestial pole.  In ancient India the star Polaris had to be found for marriages and finding it was the same way as today first finding the bucket of Ursa Major the front section points to it.  The head ( Ra1hu ) part of the dragon was all ways the ascending phase of the orbit or the northwards motion with the alignment of Polaris. The node of the moon would be half way between both the highest and lowest points.  Note below the Hexagon is formed by 6 x 4320 orbital legs.

  The Siddhaantas ( Aryabhatiya , Suryasiddhanta , Narada Purana) used a given number of planetary revolutions.  A Mahayuga or yuga equals 4320.000 revolutions ,  the moon 57753336 , Jupiter 364220.  The Ardharatrikapaksa has the same numbers for a yoga  the moon and Jupiter , it gives Saturn 146564 , mars 2296824 , Venus 7022388  and Mercury 17937020. Due to the precession of the equinox the shift through 1 degree arc was 72 orbits  today it is 71.6 .   The time period for the equinoctial shift to go through an astrological house (30 degrees) was 72 x 30 = 2160 than two houses were 2160 x 2 = 4320. The ancients multiplied the number by a factor of 1000  at the end of a calculation they would have had to divide by 1000 , today this is called in science the precision of three decimal places.     

         The planet Jupiter above was given 364220 orbits , three decimal place precision 4320.000 / 364.220 = 11.86096 here 4320 / 364.2 = 11.86161 the precise measurement of today of one orbit of Jupiter is 11.86 earth orbits  (earth orbit equals 4320/X as a ratio).  Here I want to mention the Veda has Jupiter as the most true and most auspicious of all the planets.

Saturn takes 10,759 Earth days or 29.5 earth orbits. The Vedic number of 146.564 / 4320 = 29.475.

The Siddhaantas ( Aryabhatiya , Suryasiddhanta , Narada Purana)   the moon the Veda gave 57753336 and a Yuga  4320000 Three dicmal place precession   57753.336 / 4320 = 13.3688 x  27.32167 days per lunar orbit = 365.2587 the Julian calendar is 365.25 days of 86400 SI secondsThe Earth's rotation is slowing at a rate of 0.002 seconds per day per century.  As a result of the slowing there is a Conservation of angular momentum the slowing of earth's rotation is accompanied by an increase of the mean Earth-Moon distance of about 3.8 m per century , or 3.8 m cm per orbit.

      Mars in science orbits the sun in 687 earth days.  The Vedic number 2296824 for mars in the equation 4320 / 2296.824 = 1.88  then 1.88 x 365.25636 = 686.9953 The Martian orbit is equal to 1.8809 Earth orbits,  , 320 days , and 18.2 hours , the Vedic numbers 4320 / 2296.824 = 1.88085.

      Venus in science completes an orbit of the sun in 224.65 days.  The Vedic numbers 7022388 three decimal places 7022.388 / 4320 = 1.6255527 then 365.25636 a orbits  divided by the modern number 224.65 = 1.622589.

    Mercury in science takes 88 days to complete an orbit around the sun. the Vedic numbers 17937020 , then 17937.02 / 4320 = 4.152 and 365.25636 / 88 = 4.15064.
The seal above of a buffalo is the  same   type of Indus image seal found in Mesopotamia.  The image is  Bali ; a buffalo , "Tax" , tribute , an offering , gift , oblation   or Balin ; a buffalo , strong , mighty , stout , robust   RV.   In the image the buffalo stands in front of : KhaDgapAtra ; A vessel ( formed from Buffalo's horns ) being a large salver or charger on which the sacrificial knife is laid.  This image means "tax paid" to the Sargon's sons from the Vedic Indus Valley ,  this is prior to the war of the " ten kings" , recorded in mesopotamia as Dilium giving tribute.  VAmana ; a dwarf , " the Dwarf " Name of Vishn2u in his fifth  Avata1ra or descent ( undertaken to "humble" the pride of the Daitya Bali this legend is from RV.

The precession of the equinox is a change in the orientation of the rotation axis of the earth.  This change or shift is 1 degree in 72 years ,  in the Veda this shift was used as a calendar as 15 degrees is one hour , 2 hours is one Zodiac house , 2 houses or 60 degrees equals 60 x 72 = 4320.oo a Yuga. In making this calendar you have to fix the polar stars Polaris and Thuban.

  In the Veda their was a lunar 355 years and a 366 solar , this is like the Egyptian calendar , you take  365 orbits instead of 365.25 Gregorian calendar  that is .4 x 365 = 146 so in
1460 orbits you are back to the start/star or point in the sky  , the Egyptian's used Sirius.  Sirius does fit in Vedic astronomy where 27 Naksatra's divided by 4 is 6.75  and Sirius is at the 6th hour and 45 min right accension from Polaris.

     Tropical Zodiac the sun is in Virgo from 23 August to 23 September leaving it at the moment of autumnal equinox , Sidereal Zodiac is from Septenber 17 to October 17     Sanchi is 23.4795 degrees north and the equator and ecliptic pole is 23.4393 in 2000 CE degrees from the celistial pole)
Hindu astonomy is based on the sidereal or visible zodiac , accounting for the shift of the equinoxes by a correction called ayanamsa.  The difference between the Vedic and and the Western zodiac is at 24 degrees , this corresponds to a separation of
1700 years , when the vernal equnox was in the center or the constellation Pisces and the tropical zodiac coincided with the sidereal one (around 290 Ad , or 23.86 degrees as of 2000 ). and this is the time 180 opposite Chitra and the spring equinox meet , the end of having two points to make a calculation   The Indic word to account for the shift is ayanamsa Anil-ayana = way or course of the wind , marut-ayana = "wind-passage"  , vat-ayana = moving in the wind , vy-ayana going apart , separation RV.  ayanamsa is  from Hams-ayana = goose , Swan as a vehicle.

All Mesopotamian king lists (Calendars) have the flood as a part of their recording of dates. Both calendars before and after the flood have been lost as far as our understanding of their dating system.  The first Mesopotamian calendar used a completly different system with 1000's of unites for one life time.  After the flood the second calendar used a system of about 60. The Egyptian calendar is based on a 1460 years system  The early history of Egypt prior to 2800BCE is a cultural exchange with Mesopotamia, their civilization sprung up from this exchange.  I believe the Egyptians got their written script from this early Mesopotamian influence.  Egypt did start forming their own script before the arrival of this calendar that they called Thoth (this calendar was based on the fixed star Sirius named Spdt and the Greeks called it Sothis 'a combination of Spdt and Thoth').  The Thoth calendar I believe is an Indic calendar, it whould be the Vedic solar calendar and was the second calendar employed in Mesopotamia after the flood. Thoth was the God of both the calendar and writing (computator of the times of life and ruler of the Years, the giver of speach and writing). The Mesopotamian's also have a prophet associated with this flood.  The start of the Vedic Sapta calendar also starts with the flood of Noah.  Noah was the greatest prophet of the Vedic Age, his name in Sanskrit is Manu. He was the 8th prophet of the Veda.  Their were 12 prophets of the Vedic Age in Sindhu, the land of the 7 rivers (the #7 is Sapta the calender is Saptarisa named after the great 7 prophets).

There is an old Germanic story of Manu the progenitor of mankind, where the English word Man, Mankind and hu-man originate (English is a Ger'man'ic language). In Mesopotamia the word Manu became: boat, ship and "Ark".   This view of history makes Noah the driving force behind the success of the Indo-European.   Because Noah (Manu) had the greatest influence on the Vedic Age (2800-2000 BCE, the year 2000BCE is 500 years before the Biblical Exodus of Egypt).  Manu being the greatest prophet of that age.   With the Egyptians the story took on a mythological tone in the personified creator Nun who is represented in the book of the dead as a man rising from the primordial waters holding above his head the sacred boat of the sun God. Thus Nun is the leader of the "eight genies".  These eight genies were believed to have swum together in the form of an egg in the darkness of "father" Nun.  Then from this egg burst forth the bird of light (probable roots of the famous Egyptian Phoenix).

       One capital recorded by the Mesopotamian's before the flood was Ur.  This reference to a huge flood at Ur had to be the achaeological flood at the site of Ur that was dated by Dr. C. Leonard Wooly to around 2800BCE.  This flood had 8 feet of sediment between levels.  With the Chinese story (that they eather got through cultual exchange or they too experinced it ) there are four separate accounts of the flood. Beyond reason the event happened before 4000BCE when civilization started. The Mesopotamian King lists confirm that the flood happened "after" 8 kings, their start of civilization as they knew it.  The Mesopotamian account has 8 kings and then the Flood with a prophet (Noah).  The Babylonian Utanapishtim exactly parallels the Noah flood account (Utaratutu is the 8th king in the Sumerian king list and Utanapishtim is his name after 900 years in the Babylonian account).  The Babylonian account of Gilgamesh that meets Noah is dated to around 2550BCE (the time of Gilgamesh not Babylon).  In this meeting Gilgamesh has to travel to Dilium, this is the place of paradise to the Mesopotamians.  Gilgamesh was a King and in all king lists of Mesopotamia he is generations after the flood (the flood's date is around 3000BCE and Gilgamesh was 2550BCE).  I interpret this to mean Dilium was where he had to go to find the branch of immortality (the religion of Noah went to Dilium).

\Two calendars Saptarsi prior and Kalpa or Manu after the star Thuban
vA 99 423,424    vA 99 427   Kalpa start is Jyestha and Saptarsi is Mula  ,  The Saptarsi the first calendar starts oppisite Kali same as oppisite  Krittika or when the spring equinox passes Taurus and hits todays 4th hour Krittika that is four Yuga from Polaris 4260 x 4 = 17040 orbits at Satyabesha constellation from here the spring equinox is in Mula  .  Manu or Kalpa calendar starts at 12000 years of precession from todays 1st hour and in Jyestha
852000 / 12000 = 71    864000 /12000 = 72         864000 / 4320 = 200   852000 / 4260 = 200

The construction of the Cakra  is a astronomical given in that the big Dipper points to both stars of the precision of the equinox.    From the star Polaris the 14th hour of the Vedic fixed stars is Citra "our 14th hour and the star Thuban" then a great cycle is formed from 180 degrees Citra.

1 Manu-kala = 71 Catur-Yuga       1 Manu-kala = 4260 months    The lunar orbit is 355 days and 366 days solar  ,  this is like the Egyptian calendar were you make the  365 orbits instead of 365.25 Gregorian calendar  that is .4 x 365 = 146 so in 1460 orbits you are back to the start were ever star you call the start the Egyptian's used Sirius. It may be that Sirius was Vedic where 27 Naksatra's divided by 4 is 6.75 or 6 and 45 min.
                        4260 x 4 = 17040   and 4320 x 4 = 17280      17040 / 71 = 240 degrees  17280 / 72 = 240 degrees      4320 + 4260  / 2 = 4290  4290 x 4 = 17160       1460 x 12 = 17520        17520 - 17280 = 240
              4260 / 12 = 355  above  the 355 days and 366 are to come together after 355 years         and   12 x 366 = 4392 - 72 = 4320          1460 x 3  =  4380 - 4320 = 60  

            My interest in Vedic astronomy is were Vedic astronomy explains the Indus seals. A Divya ( an example to the right) is the two dashes found on many seals ( second seal to the left) .      3030 human years is made of 60 Divya years ,    4800 Divya vatsara = 1 Krta-Yuga =  1 Sandhi or conjuction  ,    1 kalpa  =  14 Manu plus a bit 1000 /  71 = 14.084507 It is 14 Manu + 15 sandhi = 1 kalpa 
                                       3030 / 27 Naksatras = 112  over this is the five year Yuga of 5000 years = 5112         5112 / 60 = 85.2    "one manvantara is equal to 852000 divya varshas which are equal to 306720000 (paarthiva)human years.  4260 + 852 = 5112

      The eighth Manus of 14 is Saravana the first three sets of seals ( to the right ) start  Saravana Divya.  The constellation Aquila.   The divya is the two dashes. 
The Sumerian seals are below the Indus seals. Saravana the eighth started 8 x 852 = 6816 rotations that is 14 - 8 = 6 Manus prior to Polaris 12000 - 6816 = 5184 , 5184 - 72 ( 72 being the first samdhi or conjucntion ) = 5112 ,  Arayabhata gives this date 3102 BC.  as the start of the Kali Age. In that quote he was giving an example of a Yogi not the Yogi of 4320.000 , the end of Saravana  is 4260 rotations  prior to Polaris 4320 - 2010 = 2310 BC start of the Kali Age.  5112 prior to Polaris  is the start of the Manus Saravana ( 3102 BC) Then minus 852 Roatations  is the year 4260 years prior to Polaris 2250 BC.  After 350 years of the 9th Manus , one after Saravana the Indus Valley Civilization is over 1900 BC.  The next age is the Lunar Race based in Hastinpura , this was a huge center of Hindu life at that time.   2310 BC Kila Age , this is also around the date in history the chariot is introduced as a front line war machine , the chariot played a major role in MahaBharata war that ended around the recorded beginning of the Kali Age 2310 BC with the establishment of the city's Hastinpura and New Deli.
