Then when Lord Krishna departed from this world, which is said to have occurred 35 years after the war of Kurukshetra in 3067, making it the year of 3032 BCE, then Kali-yuga began to show more of its effects.
In the time line for the passing away of Grandfather Bhisma, for example, it is said that Bhisma passed away on the Magha (January-February) shukla ashtami, after the winter solstice, which leads to the date of January 13, 3066 BCE for the winter solstice.
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 Alexanders invasion which have left references to Krishna.
These are known as the Seven Sisters or Krittikas in the Vedic tradition.
So let us take a look at a few ideas from at least one angle of research on this topic. Narahari Achar, a physicist from the University of Memphis, clearly showed with astronomical analysis that the Mahabharata war took place in 3067 BCE.
Examining the Mahabharata, books 3, 5, and 18, his sky map software showed that all these descriptions converge in the year 3067.
Achar also acknowledged that some 30 years earlier, in 1969, S. In determining the date of the Mahabharata war at Kurukshetra, astronomical references in the epic can be used, of which there are more than one hundred and fifty.
Aryabhatta, one of the great mathematicians and astronomers of India in the 5 century CE, examined the astronomical positions recorded in the Mahabharata.
In his work, the Aryabhattiya, he calculated that the approximate date to be 3100 BCE, justifying the date of the Kurukshetra war to have been fought about 5000 years ago, as the tradition itself and most Hindus have always said. However, the Mahabharata itself does not describe when Kali-yuga began.
