Last updated:General information only
The content on this website, including the sleep and bedtime calculators, blog articles, and any related text, images, or graphics, is provided for general informational and educational purposes only. It is not intended to be, and should not be taken as, medical advice, diagnosis, or treatment.
No doctor-patient relationship
Using this website, including submitting the contact form, does not create a doctor-patient or any other healthcare provider relationship between you and Daily Sleep Calculator or its authors.
The calculator is an estimate, not a diagnosis
Our bedtime and wake-up time calculators are based on general averages — a sleep cycle length of approximately 90 minutes and an average time-to-fall-asleep of about 15 minutes. Individual sleep cycles vary by person, age, and night to night, and the calculator cannot detect or diagnose insomnia, sleep apnea, restless legs syndrome, narcolepsy, or any other sleep disorder.
Always consult a professional
Never disregard professional medical advice or delay seeking it because of something you read on this site. If you experience ongoing sleep problems, loud snoring with pauses in breathing, excessive daytime sleepiness, or any symptom that concerns you, speak with a physician or a board-certified sleep medicine specialist. If you believe you are experiencing a medical emergency, call your local emergency number immediately.
