About BestBedtime.net
BestBedtime.net is a simple, free sleep cycle calculator designed to help you find your best time to sleep and wake up. The goal of this website is to turn complex sleep science into clear, practical suggestions that anyone can use in everyday life.
What This Website Does
The main tool on BestBedtime.net is the Sleep Cycle Calculator. It uses 90-minute sleep cycles and your personal “time to fall asleep” to suggest several possible bedtimes or wake-up times.
Instead of guessing when you should go to bed, you can enter the time you need to wake up and let the calculator do the math. The result is a short list of options that are aligned with full sleep cycles, so you are more likely to wake up during a lighter stage of sleep and feel more refreshed.
Who This Site Is For
BestBedtime.net is for anyone who:
- wants a simple way to plan bedtimes and wake-up times,
- often feels tired even after “enough” hours in bed,
- is curious about sleep cycles but does not want to read long textbooks,
- prefers quick, practical tools instead of complicated apps.
The website is especially useful for people with fixed morning commitments, such as school or work, who want to make the most of the hours they spend sleeping.
How the Sleep Calculator Works
The calculator is based on three simple ideas:
- Your brain sleeps in cycles of about 90 minutes.
- Waking up at the end of a cycle usually feels better than waking up in the middle of deep sleep.
- Most adults feel best with around 5–6 cycles per night (about 7.5 to 9 hours of sleep).
You choose when you want to wake up (or when you plan to go to bed) and how long you usually need to fall asleep. The calculator then suggests multiple times that match full sleep cycles plus your fall-asleep time, so you can pick an option that fits your daily routine.
Privacy and Data Use
BestBedtime.net is designed to be simple and privacy-friendly. You can use the sleep calculator without creating an account or entering your real name. The times you type into the calculator are processed directly in your browser.
