What time should I go to bed to wake at 10:30 AM?
If 10:30 AM is fixed, the variable is bedtime. These options each complete a whole number of ~90-minute sleep cycles before the alarm sounds, allowing about 15 minutes to fall asleep.
| 1:16 AM | 6 sleep cycles | 9 hours of sleep |
| 2:46 AM | 5 sleep cycles | 7.5 hours of sleep |
| 4:16 AM | 4 sleep cycles | 6 hours of sleep |
These are planning figures, not medical advice — cycle length varies between people and from night to night.
