The Ancient Indians’ CALENDER SYSTEM based upon their Geo-Centric Cosmological Theories.

Introduction: The Ancient Indians were well aware of that the normal life of the living-beings on the Earth could not be followed smoothly without any planning.Hence they invented their calendar system based upon their Geo-centric and the Oneness Universe Cosmological Theories.They were well-known about the impacts of the 27 stellar,the 7 planets,the 2 shadow planets over the Earth which is positioned at the center of the integrated form of the 27 stellar-groups around the Earth which makes the Egg-shaped Oneness cosmos. They invented that the Stellar energy is the basic source for the movements of all the planets which have their movements along and parallel to the integrated and the fixed formed form of the stellar energy-line which is in the form of PETAL-LINE PATH which is not either in a regular Circular or in a regular elliptical orbits. They considered the Sun and the Moon and the fixed positions of the stellar are the basic factors including the positions of the other planets which are positioned between the Earth and the Stellar in the Cosmos for arriving their detailed Calender system.

HORA-SYSTEM: I hope the term “HORA” MEANS the duration of time of a particular planet’s influence over the Earth. Accordingly, the Ancient Indians identified the duration of time between the two consecutive Sun raises as 60 NAZHIES AND later which is known as 24 HOURS.

ORDER OF THE WEEK-DAYS; The Ancient Indians noticed the routine of Sun raises in the cosmos they found-out a way to identify the each 60 NAHIES or 24 Hour time-limit by using the order of the planets which are positioned in the Geo-centered cosmos and their influence over the Earth.From their Slogas we can identify the order of the planets from the stellar are as follows:1.Saturn, 2.Jupiter, 3.Mars, 4.Sun, 5.Venus, 6.Mercury, and 7.Moon. They distributed an even time-bound influence for each planet in the above order at the rate of 2-1/2 Nahies or ONE HOUR BETWEEN THE TWO CONSECUTIVE SUN RAISES. NOW WE CAN SEE,BETWEEN THE TWO CONSECUTIVE SUN RAISES THERE ARE THREE COMPLETE ROTATIONS WHICH ENDS AT 21 HOUR AND THE REMAINING 3 HOURS WILL BE OF SATURN,JUPITER AND MARS AND AT THE TH HOUR WHEN THE NEXT SUN RAISE TAKES PLACE WHEN THE SUN WILL BE THE FIRST PLANET TO THE SECOND PHASE OF SUN RAISE WHICH IS IDENTIFIED AS SUN-DAY AND THE FORMER ONE IS IDENTIFIED AS SATURDAY AND USING THE ABOVE ROTATION THEY HAD ARRIVED THE ORDER OF THE WEEK-DAYS AS SATURDAY, SUN-DAY, MON-DAY, TUES-DAY, WEDNESDAY-DAY, THURS-DAY, AND FRIDAY.

FIVE-ELEMENTS FACTOR:The Ancient Indians gave more importance to the Five-Elements Factors in designing their Calender system.The basic and primary five elements are 1.The Air, 2.The Heat, 3.The Water, 4.The Earth Energy ie., the Gravitational force, 5.The energy received from the Stellar and the Planets in the cosmos around the Earth.
1.DAY: A Day is defined as the time spread over between the two-consecutive Sun-raises and identified with the order of the planets which are positioned between the Integrated form of stellar and the Earth which is positioned at the center of the Cosmos which made out of the integrated form of 27- stellar-groups.Initially the first Sun raises is identified as Saturday as the Saturn occupies the first position from the Stellar and the subsequent sun-raises are identified as Sunday, Monday, Tuesday, Wednesday, Thursday, and Friday from the order of the planets Saturn,Jupiter.Mars, Sun, Venus, Mercury, and Moon between the Stellar and the Earth.

NAKSHTRA OR STELLAR GROUP: The influence of a particular Stellar Group in the Cosmos is identified on a particular day by using the movement of the Moon through a particular Stellar group which are positioned in the cosmos in ascending and descending order with reference to the Earth’s Equator or otherwise known as Cosmic-Equator

THITHI OR FULL /NEW-MOON: The Moon’s movement has been compared with the position of the Sun’s movement in the Cosmos with reference to the Fixed Stellar constellation in the cosmos.For Example, In the month of April the Sun is used to be in transit along and parallel to the Stellar groups namely Aswin, Bharani, and krithika’s first quarter portion. During that period when the moon takes it transit through the above stellar groups in its position , the Sun and moon happens to be at the same stellar groups in their positions in the cosmos which represents the New-moon or otherwise known as Amavasai. As the Moon which has a lesser circumference petal-line orbit than the Sun, has to move along the stellar force-line and reach the just opposite to the stellar groups where the Sun has a lesser transit when comparing the transit of moon and have its transit within the stellar groups and the moon and the sun happens to at a straight- line and the Full moon is occurring which is known as Poornima. It is quite interesting to note that the phases of the moon takes place due to the movement of the moon along and parallel to the CURVED PLACEMENT OF THE STELLAR GROUPS IN THE COSMOS AND THEIR FORCE-LINE WITH REFERENCE TO THE COSMIC EQUATOR.

YOGAS AND KARNAS; The Ancient Indians made their interpretations of the Yogas and karnas based upon the positions of the moon , Sun , the Stellar, and the other planets influences over the earth on a particular day.

THE CALENDER; The Ancient Indians derived their Calender system using the Nazhigai as the basic unit of time measurement.The following table will provide the details of the Ancient Indians Calender system.

An eye-lid movement = time taken to produce a sound
with the thumb and the middle
fingure. ( Nodi)
2 Nodies = 1 Mathirai
2 Mathiraies = 1 Guru
6 Gurus = 1 Swasa or Prana
6 Pranas = 1Kshna or palam
12 Kshnas = 1 Vinazhi
60 Vinazhies = 1 Nazhi
2.5 Nazhies = 1 Hour
60 Nazhies = 24 Hours or 1 Day
30 Days = 1 Month ( The moon completes
one round along and parellel
to the fixed stellar-
constellations in the cosmos.)
12 Months 1Year(The Sun completes a one round along and parallel to
the fixed stellar constellations
in the cosmos.)

The Ancient Indians further expands the year system to have greater analysis for the future forecast using the five-elements factor they have sub-divided the sixty-years in five major heads such as 1.ETHAVATHSARA, 2.EDAVATHSARA, 3.SAMVATHSARA, 4.PARIVATHSARA, and 5.ANUVATHSARA . USING THE VATHSARAS THEY USED TO FORECAST THE CLIMATIC CHANGES AND OTHER IMPORTANT HAPPENINGS THAT WOULD HAPPEN ON THE EARTH DUE TO THE MOVEMENTS OF THE PLANETS IN THE COSMOS.

AYANAS; Ayanas means movements. The Ancient Indians derived the based upon the movement of the Sun in the Cosmos.They identified the movement of the Sun through and parallel to the Fixed Stellar constellations which are positioned the Northern heme-sphere of the Cosmos and the movement of the Sun through the stellar constellations in the Southern heme-sphere of the Cosmos are known as UTHIRAAYANA AND DASHINA-AYANA respectively. Normally when the Sun enters through the stellar constellations in the Northern-heme-sphere during the middle of January and transit in the Northern portion of the Cosmos until the middle of July of every year and from the middle of July and to the middle of January of every year the Sun happens to be at the Southern heme-sphere of the Cosmos.

The Ancient Indians elaborated further their calendar system through which we can come into a conclusion the time of formation of the Oneness universe surrounded by the integrated form of the 27 stellar constellations. the elaborated table is as follows :

12 Months = 1 Deva Day
360 Deva Days = 1 Deva Year
1200 Deva Years = 1 Chathur Youga*
71 Chathur Yougas = 1 Manvanthra**
14 Manvanthras = 1 Kalpa***

* Chathur means four, the four Yougas are 1.KIRUTHA YOUGA, 2.THREYDHA YOUGA, 3.DHUVAPARA YOUGA, AND 4.KALI YOUGA.
The various time-limits for the four Yougas are as follows:

Names of the Yougas In terms of In terms of
Deva-Days one round of the Sun
along and parallel to the
integrated form of 27
stellar constellations.

1.KIRUTHA YOUGA 4800 17,28,000
2.THREYTHA YOUGA 3600 12,96,000
3.DHUVAPARA YOUGA 2400 8,64,000
4.KALI YOUGA 1200 4,32,000



KALPAS; There are seven kalpas which are known as:



The Ancient Indians used 36 digital s to have an elaborate astronomical calculations and they had named them to their placement. They are as follows:1.First digit is as one, 2.second digit as Dasamam, 3. Third digit as Sadam (hundred), 6th digit as one lack,7th as ten -lack,8th as one-crore, 9th as dasa-kodi,10th as sadha-kodi, 11th as Arbhudham, 12th as Nirbhutham, 13th as Garvam, 14th as Maha-garvam, 15th as Padmam, 16th as Maha-padmam, 17 as Kshoroni, 18th as Maha-kshoroni,19th as Sangam, 20th as Maha-sangam, 21st as Kshathi, 22nd as Maha-kshathi, 23rd as Shodam, 24th as Maha-shodam, 25th as Nidhi, 26th as Maha-nidhi, 27th as Bharatham, 28th as Parthin, 29th as Anandham, 30th as Saharam, 31st as Aryam, 35th as Bhoori, and the 36th digit is known as Maha-bhoori .

The detailed formation of the Indian Calender System is standing as a proof for their Oneness Geo-centric cosmic theories.
