Zoitra canonical content snapshot
Find the best bedtime for your wake-up time using 90-minute sleep cycles. Wake up between cycles, not in the middle of one.
Enter the time you need to wake up and the number of 90-minute sleep cycles you want, and the calculator suggests bedtimes that let you wake between cycles. Falling asleep takes about 15 minutes, so plan to be in bed a little earlier.
