If 3:00 AM is your bedtime and 9:00 AM your alarm, that is 6 hours in bed — below the 7–9 hours most adults need, so you may wake up short on rest. The catch is actually getting up at 9:00 AM; see the sleep calculator to line the wake-up time up with a full sleep cycle.

A sleep forecast before bed, bedtime reminders and wake-up streaks — because the 6 AM problem usually starts at 1 AM.
