A calculator that respects your time and your sleep.
Our editorial standard
BedtimeCalculator.net is built around one job: helping you wake up at the end of a sleep cycle instead of the middle of one. Every calculation, recommendation, and article is fact-checked by our editorial team against guidance from the American Academy of Sleep Medicine (AASM) and the National Sleep Foundation (NSF).
We do not claim to be a substitute for medical advice. If you have a sleep disorder — chronic insomnia, sleep apnea, narcolepsy, restless legs — talk to a sleep medicine specialist.
