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.
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.
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.
