The idea of "beauty sleep" isn't just a saying — sleep plays a real role in skin repair, under-eye appearance, and overall energy the next day. Sleep researchers generally recommend that adults get between 7 and 9 hours of sleep per night, cycling through roughly 90-minute sleep stages.
This calculator uses your intended wake-up time to suggest ideal bedtimes based on completing full sleep cycles, so you're more likely to wake up feeling rested rather than groggy from being woken up mid-cycle.
Sleep happens in cycles of about 90 minutes, so the suggested times are spaced to help you wake up at the end of a cycle rather than in the middle of one.
Most adults feel best with 5 to 6 full sleep cycles, which is roughly 7.5 to 9 hours of sleep.
