The Sleep Cycle Calculator helps you identify the perfect bedtime or wake-up time to avoid grogginess. A typical sleep cycle lasts about 90 minutes, and waking up in the middle of a cycle can make you feel tired. This tool calculates your sleep times in 90-minute intervals, so you can wake up at the end of a cycle and feel refreshed and energized.
