VEDIC EVIDENCE OF THE SIDEREAL YEAR

The Rig Veda, the earliest of the Hindu scriptures says the following : 

    Twelve spokes, one wheel, navels three. 

    Who can comprehend this?

    On it are placed together three hundred and sixty like pegs. 

    They shake not in the least.

                                                     ( Dirghatama Rishi, Rig Veda 1.164.48 )

    A seven-named horse does draw this three-naved wheel.... 

    Seven steeds draw the seven-wheeled chariot.....

    Wise poets have spun a seven-strand tale

    around this heavenly calf, the Sun

    ( DirghatamaRishi, Rig Veda 1.164.1-5 )
The number seven related to the Sun has much significance when understanding the third mean solar motion ( 0.2563795 ). The Kali-yuga of 432,000 years is the unit of reference for determining the length of the sidereal year in Hindu cosmological time cycles. During the course of 10,000 years there are seven rotations of the third mean solar motion. For a single year the count is 0.2563795 diumal revolutions of the earth. For two years it is .512759 and so on. One complete rotation ( to equal 366.2564...) of the third motion takes 1428.571429 sidereal years. Or you can reduce it to a fraction of 1428 4/7 sidereal years.
366.2563795...       10000
                                                                      ...........................  = ............   = 1428 4/7 years
                                                                            0.2563795...           7

The integer of this sidereal interval, 1428 years, multiplied by the number of years in a Kali-yuga and then further multiplied by seven equals the number of years of fourteen Manus. (see table 4).

                       1428 X 432,000 X 7 =  4,318,272,000 =  14 MANUS

The fractional part of this sidereal interval, 4/7 years, multiplied by seven and further multiplied by the number of years in a Kali-yuga equals the time of an introductory dawn ( see table 4 ).

                      ( 4/7 ) x 7 x 432,000 = 1,728,000 years =  introductory dawn.

Relating the Vedic verses above to what we have just demonstrated it is clear that the "navels three" refer to the three mean motions of the Sun and "seven-wheeled chariot" to the rate of precession of the equinoxes. Thus, there can be no doubt that the cosmological time cycles were already an established conclusion at the time of the Vedic era and not in the formative stages.
