Quite a number of efforts have been made by various scholars to find the date of the Mahabharata War.Various methods have been used, using historical references in the Puranas, language conditions, archaeological findings etc. Vartak from Pune carefully studied the astronomical references in the Mahabharata and corroborated the same with historical and archeological evidences. Vartak are more accurate than the various other dates propounded by other scholars who have been carried away by the statements made by Western scholars. A few have used astronomical methods to determine the time of the Mahabharata. All in all, it is possible to state that the dates as derived by Dr. They have been prejudiced against the richness of the Indian Civilization in the past and have always tried to attribute much later dates and consequently lo denigrate the glorious past of India. Vartak has derived the date of the initiation of the Mahabharata War to be 16th October 5562 B. This proposed date has been examined by a few scholars and has been verified. It is possible to determine the date of an astronomical reference by considering the movements of the planets including the Sun and the Moon in the various constellations of the sky, the movement of the Earth with its axis inclined to the ecliptic and the precession and nutation of this axis as well as the seasonal changes referred to in the text. This may prove to be a break-through in deciding the chronology of the events in the history of India (and probably the World). Vartak has also derived the dates of Ramayana and the Vedas which has also been published as a book. This is the problem that people who push for an earlier date fail to address.That leaves only the 1100 – 900 BCE date open and during that period Painted Grey Ware was found in most of the sites associated with the epic suggesting habitation. Puranic texts mention that when Hastinapura was destroyed by floods, people moved to Kaushambi.
In the 1950s, archaeologists excavated various sites related to the Mahabharata and from that data we have an understanding of that period.Among the dates proposed for Mahabharata, there are a few major ones.To keep this in context, remember that the Mature Harappan Period was from 2500 – 1900 BCE.Sometimes each of these groups are fixated by their technique and ignore the others.But whatever be the technique — textual analysis or astronomical analysis — it has to reconcile with what archaeology has found on the ground.Among those interested in finding a date, there are many camps; some depend on puranic genealogies, others look at astronomical data, others use Aryan Invasion/Migration etc.
