About Sleep Calculator
Sleep Calculator is a easy-to-use extension that helps you optimize your sleep schedule by calculating the best times to go to bed or wake up based on natural sleep cycles. Wake up feeling refreshed and energized by aligning your sleep with complete cycles.
How It Works
Sleep cycles typically last about 90 minutes. By aligning your bedtime or wake time with complete cycles, you can wake up during lighter sleep phases, feeling more refreshed and alert. The calculator accounts for your personal sleep latency (the time it takes you to fall asleep) to provide accurate recommendations.
P.S. This extension is designed to help you plan your sleep schedule. Individual sleep patterns may vary, and the calculator provides recommendations based on the standard 90-minute cycle model.
