Why Kali Yuga Is Said to Begin the Day Krishna Left

Kali Yuga has a start date, and it is unusually specific for a cosmological age: by the traditional reckoning, midnight between 17 and 18 February, 3102 BCE. The Puranas give the narrative version. Kali could not enter the world while Krishna walked in it, the Bhagavata says, and the age began on the day Krishna left his body, shot in the heel by a hunter while resting in the forest after the destruction of his own Yadava clan. Dvaraka was swallowed by the sea soon after. The texts that tell this story treat Krishna’s departure as the hinge between two ages, the last presence holding the old one open.

The precise date comes from a different kind of source, and it is worth being clear about which. The fifth-century astronomer Aryabhata states in his Aryabhatiya that he was twenty-three years old when 3,600 years of the Kali Yuga had passed; since he was writing around 499 CE, that places the epoch in 3102 BCE. Indian astronomers used this epoch as the zero point for their calculations, and several describe it as a moment when the planets stood in a near-conjunction. Modern back-calculation shows the planets were not in any tight alignment on that date, so the epoch is best understood as a computational convention, a convenient zero chosen by astronomers, rather than an observation someone recorded at the time.

That matters for how the date gets used today. It is often cited as though it fixes the Mahabharata war and Krishna’s life to around 3100 BCE as established history. Historians do not generally accept that; the archaeological and textual evidence for the epic’s setting points much later, and the dates proposed for the war vary widely. The honest summary is that 3102 BCE is a very old and very useful astronomical epoch, anchored to a sacred narrative, and that treating it as a documented historical date asks it to carry more weight than it can.

None of this diminishes what the tradition is saying with the story. An age of loss beginning at the exact moment the divine presence withdraws from ordinary sight is a statement about what Kali Yuga is: not a period of cosmic punishment, but a time in which the sacred has to be sought rather than simply met. The Bhagavata’s consolation follows directly from that. In this age, it says, the practice that works is the simplest one available, remembering and chanting the names, a practice suited precisely to people who can no longer see the one they are calling.
