As stated in the Puranas, Kali-yuga had already begun, but its full influence was held back because of the presence of Lord Krishna. 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.According to Puranic sources,Krishna’s disappearance marks the end of Dvapara Yuga and the start of Kali Yuga, which is dated to February 17/18, 3102 BCE.Astronomically simulated Eclipses and Greek Records place the year at 3031 BC.
