What time should I go to bed to wake up at 5:30 am?

To wake up at 5:30 am, go to bed at 8:15 pm (9 hours of sleep), 9:45 pm (7.5 hours), or 11:15 pm (6 hours). Each bedtime allows 15 minutes to fall asleep and ends on a full 90-minute sleep cycle. Most adults need at least 7 hours, so 8:15 pm or 9:45 pm is the better target.
