Sleep Calculator is a web-based tool designed to help users determine optimal bedtimes and wake-up times based on natural 90-minute sleep cycles. By aligning sleep schedules with these cycles, the tool aims to support waking up at the end of a complete cycle, which can help users feel more alert and refreshed in the morning.
The calculator allows individuals to input either their desired wake-up time or sleep time. It then works backwards or forwards using 90-minute increments, incorporating a 14-minute buffer to account for the average time it takes to fall asleep. This approach is intended to ensure users complete either five or six full sleep cycles per night, as recommended by sleep science. The tool also provides information on recommended sleep durations for various age groups, from newborns to older adults, helping users understand age-appropriate sleep needs.
Delivered as a free online service, Sleep Calculator is accessible through its website. It does not require installation or payment, and is positioned as a resource for anyone seeking to improve their sleep quality by timing their rest according to sleep cycle science.
