As the *Guanfo sanmei jing* says, among the hungry ghosts, those with the longest lifespan live for 84,000 years, while shorter spans are indefinite. According to the *Tattvasiddhi-śāstra*, the longest lifespan is 70,000 years, while shorter spans are also indefinite. If one relies on the *Upāsaka[-śīla]-sūtra*, the longest lifespan is 15,000 years, where 5,000 years among humans equals one day and one night among hungry ghosts; with days and nights like this, the ghosts' lifespan is 15,000 years (calculating by the days, months, and years of the human realm, this corresponds to 27,000,000 years). If one relies on the *Saddharmasmṛtyupasthāna-sūtra*, there are ghosts whose lifespan is 500 years, where ten years among humans equals one day and one night for the hungry ghosts; with days and nights like this, their lifespan is 500 years (calculating by the days, months, and years of the human realm, this corresponds to 1,800,000 years).
