Rounding off to the next higher integer we get 30 days during which, the average solar motion is 30 Degrees. The relative motion between the Sun & Moon shows that the Synodical Month (new moon to new moon or full moon to full moon) is 29D 12H 44M 3S = 29.53059D. The zodiac of 12 signs and 27 constellations was prepared by carefully observing the movement of the Sun and Moon in the geocentric model of the universe. To clear these doubts, it is necessary to understand the basis of this primary division called Rasi. Every now and then a new planet is seen and the doubts arise in the minds of the learned on the continued validity of the twelve sign zodiac. The division of the zodiac into twelve signs and twenty seven (or twenty eight Nakshatra) is the primary division in the paradigm of Vedic Astrology. As we study each of the divisions, we will also examine the time measure represented by it and will get additional clues to interpret results and delineate the effect of time on the division. Thus, the first and foremost point to bear in mind is that every division of the zodiac has a similar or matching division of time.

Normally the Bhachakra is represented as a two dimensional figure for easy reading on paper, but the other dimensions of a dynamic linear time and the vertical declination of the planets were also examined and noted.

The great Vedic thinkers personified God as Kalapurusha and harmonized these two concepts of time and space into the four-dimensional model of Bhachakra (geocentric zodiac).

The definition of the beginning of a linear time scale or the starting point of the Universe has been the vexed question of many a thinker and this thought leads the mind to a definition of God as being imperceptible. Time and space are like endless rings without a beginning and without an end. Our modern science, after labors of hundreds of years has simply proved them to be correct…. We must not forget that it was the Hindus who discovered what is known as the precession of the Equinoxes, and in their calculation such an occurrence takes place every 25,827 years.
