Free Sleep Calculators With Clear Assumptions

Updated October 20, 2026

Best Time For Bed is a small, independent site that helps people plan sleep timing. It started with a simple question many of us ask at 10 PM: if I need to be up at 6:30, when should I actually go to bed? The calculators answer that, and the guides explain the reasoning behind the numbers.

Key takeaways

We build free, no-sign-up sleep calculators and plain-English guides.
Content is based on published guidelines and cited sources.
We are not medical professionals and do not give medical advice.

What we do

We make a set of free tools: a sleep calculator, bedtime and wake-up time calculators, a nap calculator, a sleep debt calculator, a chronotype quiz and others. Alongside them are guides on sleep habits, health and routines.

Meet the editor

Nauman is the founder and editor of Best Time For Bed. He builds the calculators and writes and edits the guides, working from published guidance from organisations such as the American Academy of Sleep Medicine, the National Sleep Foundation and the CDC, and from peer-reviewed studies. He is not a doctor or a sleep specialist, so the site focuses on explaining established guidance and pointing people to professional help when they need it.

Why you can trust the content

We cite our sources on every guide and on the sources page.
We show an updated date on each page.
We say when evidence is limited.
We separate advertising from editorial decisions.

Medical review

Our guides are not currently medically reviewed. If a qualified clinician reviews a page, we will name them on it. Until then, please treat everything here as general information.
