Common Bedtimes

Choose when you plan to go to bed to see suggested wake-up times.

Which wake-up time should you choose?

6:15 AM (next day) allows approximately 9 hours of sleep; 4:45 AM (next day) allows approximately 7.5 hours of sleep. Choose a wake-up time that meets your needs and fits your responsibilities; the longest option is not necessary for everyone. Cycle timing cannot guarantee alertness.

Shorter options are comparisons, not recommended targets for most adults. Prioritize enough sleep and consistency. Check the sleep-duration guidance for your age.

Durations describe the 90-minute model, not guaranteed time asleep. Read the formulas and rounding explanation and calculator accuracy guide. For morning alarms, after-midnight bedtimes are earlier on the same calendar day; evening bedtimes are the night before. For bedtimes after midnight, the listed alarms are later that same day; evening bedtimes lead to alarms the next day.

Read time in bed versus time asleep to distinguish bedtime from sleep onset, or how to choose between estimated wake-up times.

Example sleep schedule for a 9 PM bedtime

  • 8:15 PM (same day) — Begin winding down
  • 8:45 PM (same day) — Get ready for bed
  • 9:00 PM (same day) — Go to bed
  • 9:15 PM (same day) — Estimated sleep onset
  • 4:45 AM (next day) — Wake up

This example follows the 7.5-hour sleep option and assumes 15 minutes to fall asleep: 7 hours 45 minutes in bed. Preparation times are illustrative, not required. Day labels are relative to the preset bedtime day.

Quick Tip for a 9 PM Bedtime

With a 9 PM bedtime, check whether your required alarm allows enough sleep after the fall-asleep allowance. If it falls before an adequate-duration option, use Change bedtime to compare an earlier start rather than assuming fewer blocks meet your needs.
