Which bedtime should you choose?

12:45 AM allows approximately 9 hours of sleep; 2:15 AM allows approximately 7.5 hours of sleep. Choose a bedtime 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.

See the 6 AM and 7 AM examples in the guide to choosing a bedtime and the guide to keeping a repeatable schedule.

Example evening schedule for a 10 AM wake-up

  • 1:30 AM (same day) — Begin winding down
  • 2:00 AM (same day) — Get ready for bed
  • 2:15 AM (same day) — Go to bed
  • 2:30 AM (same day) — Estimated sleep onset
  • 10:00 AM (same 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 wake-up day.

Quick Tip for a 10 AM Wake-Up

For a 10 AM alarm, after-midnight bedtimes are earlier that same day; evening bedtimes are the night before. Consider your following-day routine before shifting the schedule. A later alarm can create sleep opportunity without requiring you to delay bedtime.
