Bedtime calculator

What time should you go to bed?

Sleep runs in ~90-minute cycles, and mornings feel better when the alarm lands between cycles, not mid-dream. Nothing you enter leaves this page.

Most people take about 15 minutes to drift off; cycles average ~90 minutes but genuinely vary from person to person.

Keep in mind

  • ●These are averages. Real cycles run roughly 80–110 minutes and stretch as the night goes on — treat the times as targets, not physics.
  • ●Consistency beats optimization: the same bedtime and wake time daily does more than any calculator.
  • ●The snooze button restarts a cycle you can't finish — nine more minutes usually buys a groggier morning.
  • ●If your mind won't idle once the lights are off, steady sound helps — that's the part Hush handles.

Averages, not medicine. This calculator is an educational planning tool built on population averages — it is not medical advice, and Hush is not a treatment for insomnia, sleep apnea, or any sleep disorder. If sleep is a persistent struggle, that's worth a conversation with a clinician.
