Bedtime by age
Between 7:00 and 8:30 pm for most 5-year-olds who wake up around 6:30. Five-year-olds need 10 to 13 hours of sleep a day, most have stopped napping, and kindergarten makes their days longer than they've ever been.
Lights out between 7:00 and 8:30 pm.
Tonight, counted back
An hour and a half out leaves room for a bath without rushing.
Or screens off, on a night without a bath.
How much sleep: the American Academy of Sleep Medicine recommends that children 3 to 5 years old sleep 10 to 13 hours per 24 hours, naps included. Each window below counts back 10 to 11½ hours of night sleep from wake-up, rounded to the nearest 15 minutes. The later end is the least sleep, so lean early if they take a while to fall asleep or woke up tired.

Sleep hours come from the American Academy of Sleep Medicine's consensus statement on how much sleep children need (Journal of Clinical Sleep Medicine, 2016), which the American Academy of Pediatrics endorsed. The lights-out windows are our own arithmetic inside that range, not medical advice. Every kid is a little different. If you're worried about how your child sleeps, ask their pediatrician. For any age and wake-up time, use the bedtime calculator.
Knowing lights out is the easy part. Nightlight plans the two hours before it: a dinner that fits the energy you have left, then every step, timed back from 7:45.
