How does a sleep cycle calculator work?

A sleep calculator uses the roughly 90-minute sleep cycle to suggest bedtimes or wake times. By aligning your wake-up with the end of a full cycle rather than the middle, it aims to help you wake feeling more refreshed and less groggy.

How do I use the sleep calculator?

Enter the time you want to wake up, or the time you plan to sleep, and the tool works backward or forward in 90-minute cycles. It also allows time to fall asleep, then lists the best target times that land between cycles.

How many sleep cycles should I aim for?

Most adults do best with five to six complete 90-minute cycles, which works out to roughly seven to nine hours of sleep. Waking at the end of a cycle, rather than mid-cycle, tends to leave you feeling more rested.
