This again identifies the year of 3102 BCE. However, the Mahabharata itself does not describe when Kali-yuga began. All it says is that the war took place some time during the interval of Dvapara and Kali-yugas, and it certainly took place before Lord Krishna left this world. But there is evidence that Kali-yuga had already begun before Lord Krishna disappeared.
In the Bhagavata Purana (1.15.36) it is explained, “When the Personality of Godhead Lord Krishna left this earthly planet in His selfsame form, from that very day Kali, who had appeared partially before, became fully manifest to create inauspicious conditions for those who are endowed with a poor fund of knowledge.”
Therefore, Kali-yuga had already appeared, but it was only due to the presence of Lord Krishna who was holding back its influence. But after He left this world, Kali’s full potency took effect, which is also stated in the Kali-raja Vrittanta. Thus, the war is most likely to have been in 3067 BCE and the beginning of Kali-yuga accepted as 3102 BCE.
Some people, such as Max Muller and others, have had trouble accepting this date as the time of the Mahabharata, because they felt that the descriptions of the planetary positions of the Saptarishis (Ursa Major) were not real. However, a similar description is also given in the second chapter of the twelfth canto of the Bhagavata Purana, which helps verify the time of the Mahabharata.
One particular point to consider is that it has been shown that the positions of the Saptarishis, as explained in the work of Anthony Aveni, noted author of The Empire of Time: Calendars, Clocks and Cultures, that in many cultures, even in Africa and American Indian cultures, it is believed that the entire solar system revolves through the galaxy of the Milky Way, around the brightest star of the Pleiades, in the Taurus constellation. These are known as the Seven Sisters or Krittikas in the Vedic tradition. The brightest star in the Pleiades is Alcyone, and the sun completes one revolution around this star in approximately 3000 years. This has made the Pleiades a sacred object in the sky in many cultures. But the point is that it is this periodic revolution that is why the Saptarishis repeat their positions described in the Bhagavata Purana every 2700 years. Thus, when calculations are based on the position of these stars, we have to realize that the Vedic texts, including the Ramayana and the descriptions therein, could be relating to time periods much earlier than we think.
Additional evidence that can help establish the time of Lord Krishna was in Mohenjodaro, where a tablet dated to 2600 BCE was found which depicts Lord Krishna in His childhood days. This shows that Lord Krishna was popular at least prior to this date.
We also have records from Greek travelers who came to India following Alexander’s invasion which have left references to Krishna. Authors like Pliny referred to Krishna as Heracles, based on Hari Krishna. They record that Heracles (Krishna) was held in special honor by the Sourseni tribe (Shuraseni, based on Shura the father of Vasudeva and grandfather of Lord Krishna) in such places as the major city of Methora (Mathura).
