What is a Sleep Calculator?

The sleep calculator is a free tool that estimates what time is best for waking up and sleeping. It also returns multiple sleep or wake-up time results based on the given inputs.

Note: The average human takes 15 minutes to fall asleep. So, the calculator includes these 15 minutes in the final results.

How to Use the Sleep Calculator?

First, select your age range from the dropdown options.
The tool provides two tab options. The first one is to calculate the sleep time and the second one is for wake-up time. So, choose the required one.
Now input the time when you want to sleep or wake up.
Press the 'Calculate' button to obtain the results.
As a result, the tool shows four different time results. The first and second result is the most recommended for an adult person. Because it includes 5-6 sleep cycles that normal humans need. Each sleep cycle is 90 minutes.
