Astronomical Dating of one Rig Vedic Verse
Earth’s axis of rotation “wobbles,” causing constellations, as viewed from Earth, to drift at a constant rate and along a predictable course over a 25,000-year cycle.

Using the same kind of calculations as I have explained in the above links, the Rig Veda has been dated by others at 6500 BC. A Rig Vedic verse that observes winter solstice at Aries can be correlated to around 6500 BCE. Frawley states, “Precessional changes are the hallmark of Hindu astronomy. We cannot ignore them in ancient texts just because they give us dates too early for our conventional view of human history.”
So we know that at least that one verse was composed in 6500 BC.
Below is some info on moving equinoxes: The word originally below refers to western astronomy.
For the Rig Veda It was the WINTER SOLSTICE and not the Vernal Equinox that was in Aries.

“The date (near March 21 in the northern hemisphere) when night and day are nearly the same length and Sun crosses the celestial equator (i.e., declination 0) moving northward. In the southern hemisphere, the vernal equinox corresponds to the center of the Sun crossing the celestial equator moving southward and occurs on the date of the northern autumnal equinox. The vernal equinox marks the first day of the season of spring. The right ascension at the vernal equinox ?originally? was in the constellation Aries and the point of crossing was known as the first point in Aries (now actually in Pisces because of precession
).

Thank you very much. This is really very interesting, since I also happened to read another article using a different information to date the veda astronomically and arrive at almost the same date mentioned above. We have a lot of ancient history to be rewritten.
