What is this?
Helps you find the best times to sleep or wake up based on sleep cycles.
How to Use the Sleep Calculator
Sleep has an influence on everything from energy levels to focus and mood. However, despite all the information about sleep, a large number of individuals go to bed and wake up according to habit without thinking about how sleep cycles.
“The Sleep Calculator can help you make better decisions about sleeping. Rather than making guesses about when to go to bed and when to wake up, it makes use of natural rhythms in your sleep patterns to determine optimal times for sleeping and waking in order to help you feel refreshed instead of groggy.”
If it is about to be an early wake-up or simply adjusting an irregular sleeping pattern or just wanting to enhance the quality of sleep, this application gives one expert advice on how the body is sleeping.
1. Choose Calculation Mode
Choose whether to calculate the best bedtime or wake-up time. There is also a choice to calculate the timings in either sleep cycles or desired number of hours of sleep.
2. Enter Your Time
Enter the time when you would like to wake up or the time you would like to sleep. This time is used as a reference for the best sleep schedule.
3. Account for Sleep Onset
The calculator also factors in an average 10-15 minute interval to allow for the time it takes to go to sleep and makes more realistic estimates as a result.

There will be several suggested bedtimes or waking times based on full sleep cycles rather than partial sleep cycles.
5. Pick the Best Option for You
Select the time that fits your schedule and routine and also provides ample time for sleep cycles.
