Sleep cycle calculator: when to go to bed

Pick the time you want to wake up and see bedtimes that match whole sleep cycles.

ON THIS PAGE

What it does

Choose the time you want to wake up and how long you usually take to fall asleep. It suggests bedtimes that line up with whole sleep cycles.

When it helps

Waking up in the middle of a cycle can feel heavier than sleeping a little less. The calculator counts back from your wake-up time, adds the time you usually need to fall asleep and suggests a few bedtimes. It is an estimate, so adjust it to how you actually feel.

A word of care

The calculators are a form of play and reflection. They are not medical advice, a diagnosis or a replacement for a professional. If you are struggling, please talk to someone you trust or to a doctor.
