What Is the Sleep Cycle Calculator?

The Sleep Cycle Calculator is a tool that allows you to estimate the best time to go to sleep in order to wake up feeling rested and refreshed. It is based on the science of sleep cycles, which are periods of light and deep sleep.

Why Is Sleep Cycle Important?

The average person has four or five sleep cycles per night, each lasting about 90 minutes. Waking up in the middle of a sleep cycle can leave you feeling groggy and disoriented. But if you wake up at the end of a sleep cycle, you'll likely feel more rested.

How Does the Sleep Cycle Calculator Work?

The Sleep Cycle Calculator uses your bedtime and wake-up time to estimate the best time to go to sleep or wake up. It also takes into account the length of your sleep cycle, which is typically 90 minutes.

How to Use the Sleep Cycle Calculator

To use the Sleep Cycle Calculator, enter your bedtime or wake-up time. Then, click on the "Calculate" button. The calculator will then provide you with an estimate of the best time to sleep or wake up.
