What time should I go to bed? Every wake-up time, 15 minutes apart

Pick the time your alarm goes off. Each page gives three bedtimes that end on a full 90-minute cycle, a timeline of the night, and the research behind it.

Counts in 90-minute cycles plus 15 minutes to fall asleep. How we calculate

Standard mornings (8:00 am – 9:45 am)

Late morning (10:00 am – 11:45 am)

Afternoon and evening — shift schedules (12:00 pm – 11:45 pm)
