Before You Reach Out
Get Sleep Calculator is a free resource built to help you work out the best times to go to bed and wake up based on natural 90-minute sleep cycles. A lot of the questions we receive are already covered across the site, so you may find an instant answer below before sending a message. If your question is about how a specific result was calculated, it usually helps to mention the bedtime or wake-up time you entered so we can reproduce exactly what you saw.
How quickly will I get a reply?
We read every message and aim to respond within 24–48 hours on weekdays. Replies can take a little longer over weekends and holidays. If you don't hear back, please check your spam folder, as automated replies are sometimes filtered there.
I think a calculation looks wrong — what should I do?
Our calculators add roughly 15 minutes for the time it takes the average person to fall asleep, then count backwards or forwards in full 90-minute cycles. If a result looks off, tell us the exact time you entered and the result you expected, and choose “Bug Report” as the subject. You can also try our sleep calculator or bedtime calculator to compare.
Can you give me personal medical or sleep-disorder advice?
Our guides are for general education only and are not a substitute for professional care. If you regularly struggle to fall asleep, wake unrefreshed, or suspect a condition such as insomnia or sleep apnea, please speak with a doctor. You may still find our insomnia guide and sleep hygiene tips a useful starting point.
Do you accept partnerships, guest posts, or advertising?
We're open to relevant collaborations that genuinely help our readers sleep better. Select “Partnership / Advertising” as the subject and include a short description of what you have in mind. Please note we don't publish low-quality or unrelated link placements.
How We Use Your Feedback
Get Sleep Calculator is shaped by the people who use it. When you report a confusing result, a calculation that looks off, or a feature you wish existed, it goes onto a real list that guides what we build and fix next. Many of the calculators and guides on this site exist because a reader asked for them. So if something isn't working the way you expect, telling us genuinely helps — not just you, but everyone who visits after you.
We aim to keep this site fast, free, and free of clutter, which means we read feedback carefully rather than chasing every trend. Bug reports are prioritised first, followed by clear, widely useful improvements. We can't promise to act on every suggestion, but every message is read by a human, and we genuinely appreciate the time you take to send one. For anything related to how your information is handled, our privacy policyexplains exactly what we do and don't collect.
Other Ways We Can Help
Before you wait on a reply, it's worth knowing that many answers are already a click away on this site. If your question is about timing — when to go to bed, when to wake up, how many cycles you're getting — the calculators on the homepage and in the tools section give instant, personalised results. If it's about the science behind a recommendation, our guides cover sleep cycles, sleep stages, circadian rhythm, sleep debt, and more in plain language. We've tried to anticipate the most common questions so you don't have to wait for an email to get moving.
We also genuinely value corrections. This site translates published research from organisations like the National Sleep Foundation, the CDC, and the American Academy of Sleep Medicine into practical tools, and if you ever spot something that looks inaccurate or out of date, telling us helps keep the information trustworthy for everyone. Choose “Content Correction” as your subject and point us to the specific page and claim, and we'll review it against the sources. Accuracy matters more to us than being right, so well-sourced corrections are always welcome.
Finally, please remember that everything on this site is general educational information, not personal medical advice. If you're dealing with a persistent sleep problem — trouble falling or staying asleep most nights, loud snoring, or daytime exhaustion despite enough hours — the most helpful step we can point you toward is a conversation with a qualified doctor, who can assess your individual situation in a way no website can.
