Bedtime calculator
Based on American Academy of Sleep Medicine recommendations, endorsed by the AAP. We allow about 20 minutes to fall asleep.
Recommended for 6–12 years: 9–12 hours a night.
Lights out by
7:55 PM
Works well anywhere from 6:25 PM to 9:25 PM.
Start the wind-down 30–45 minutes before, with screens off and lights dim. Teens naturally shift later, so a consistent wake time and a phone parked outside the bedroom help more than an early bedtime alone.
