Hi, welcome to tama talk
Sleep schedule for babies: Naps five minutes during the hour.
Sleep schedule for toddlers: Goes to sleep at 8pm, wakes up at 7am.
Sleep schedule for teens: Goes to sleep at 8pm, wakes up at 7am.
Sleep schedule for adults: This can vary depending on which tamagotchi you have. For example, Kuromametchi will go to bed at 10pm while other adults go to bed at 8pm or 9pm. I believe all adults wake up at 7am (but I could be wrong but the majority of adults that I've experienced wake up at 7am)
