Relying on what is stated in the Abhidharma treatises: regarding the lifespans of the devas, fifty human years constitute one day and one night for the Cāturmahārājakāyika devas. Using this count of days, months, and years, the lifespan of the Cāturmahārājakāyika devas is five hundred years. Calculated in human days, months, and years, this is nine million years, which is precisely one day and one night in the Saṃjīva Hell. With such a count of days, months, and years, the lifespan in the Saṃjīva Hell is five hundred years. Calculating one hundred human years as one day and one night for the Trāyastriṃśa devas, with such a count of days, months, and years, the lifespan of the Trāyastriṃśa devas is one thousand years. Calculated in human years, this is thirty-six million years, which is precisely one day and one night in the Kālasūtra Great Hell. With such a count of days, months, and years, the lifespan in the Kālasūtra Hell is one thousand years. Calculating two hundred human years as one day and one night for the Yāma devas, with such a count of days, months, and years, the lifespan of the Yāma devas is two thousand years. Calculated in human years, this is one hundred and forty-four million years, which is precisely one day and one night in the Saṃghāta Great Hell. With such a count of days, months, and years, the lifespan in the Saṃghāta Great Hell is two thousand years. Calculating four hundred human years as one day and one night for the Tuṣita devas, with such a count of days, months, and years, the lifespan of the Tuṣita devas is four thousand years. Calculated in human years, this is five hundred and seventy-six million years, which is precisely one day and one night in the Raurava Hell. With such a count of days, months, and years, the lifespan in the Raurava Hell is four thousand years. Calculating eight hundred human years as one day and one night for the Nirmāṇarati devas, with such a count of days, months, and years, the lifespan of the Nirmāṇarati devas is eight thousand years. Calculated in human years, this is two billion three hundred million years, which is precisely one day and one night in the Mahāraurava Hell. With such a count of days, months, and years, the lifespan in the Mahāraurava Hell is eight thousand years. Calculating one thousand six hundred human years as one day and one night for the Paranirmitavaśavartin devas, with such a count of days, months, and years, the lifespan of the Paranirmitavaśavartin devas is sixteen thousand years. Calculated in human years, this is nine billion two hundred and sixteen million years, which is precisely one day and one night in the Tapana Great Hell. With such a count of days, months, and years, the lifespan in the Tapana Great Hell is sixteen thousand years. The lifespan in the Pratāpana Great Hell is calculated as half a kalpa; the lifespan in the Avīci Great Hell is one kalpa. The maximum lifespan in the animal realm is also one kalpa. As stated in the Bodhisattvabhūmi-śāstra, the maximum lifespan of nāgas, pretas, and the like is five hundred years.
