A sleep cycle calculator is a valuable tool designed to optimize sleep patterns by aligning them with the body's natural circadian rhythms. Understanding and leveraging these rhythms can significantly enhance the quality of sleep, leading to improved overall well-being and productivity.

Using a sleep cycle calculator is straightforward. Users input their desired wake-up time, and the calculator suggests optimal bedtimes that allow for complete sleep cycles. Alternatively, users can input their bedtime, and the calculator will recommend the best times to wake up.
