The regnal years of Bimbisāra and Ajātasattu

Later addition

This entry is not an event but a basis for reckoning years. The Sri Lankan chronicles, the Dīpavaṃsa and the Mahāvaṃsa, and the commentary on the Vinaya of the Southern tradition record that reigned fifty-two years, thirty-seven of them contemporary with the Buddha, and that reigned thirty-two years, the Buddha passing away in the eighth year of his reign. On this basis Ajātasattu's accession is reckoned here as Year 38 after the Awakening, and many events of the Buddha's last years take it as their starting point.

Different Accounts

How Bimbisāra came to the throne: the Dīpavaṃsa says he succeeded on his father's death; the Mahāvaṃsa says his father himself performed his consecration.

More differences between accounts (2)

The regnal years recorded in the Chinese Shanjian lü piposha differ from those of the Southern tradition.

The other reckoning: if “passing away in the eighth year” is taken to mean after eight full years of the reign, Ajātasattu's accession becomes Year 37 after the Awakening.

Dating

The result of the conversion is Year 38 after the Awakening (the Buddha aged seventy-two). This is worked out from the regnal years in the chronicles; the canonical texts themselves do not say in which year after the Awakening Ajātasattu came to the throne.
