Use this tool to determine the optimal time to go to bed, or the best time to wake up, based on the 90-minute sleep cycle principle.
The **BBQ Kit Sleep Cycle Calculator** is a simple, free online tool designed to help you wake up feeling energized and refreshed. It works by aligning your wake-up or bedtime with the natural 90-minute human sleep cycle. Waking up at the end of a full cycle is scientifically proven to reduce grogginess and combat that tired, confused feeling you get after a bad night's sleep.
When you enter your desired wake-up time, the calculator suggests the ideal times you should aim to fall asleep. Conversely, if you enter your current bedtime, it suggests the best times to wake up. Remember to account for the average 14 minutes it takes the average person to fall asleep! Use this tool along with our other productivity tools to optimize your entire day, not just your sleep.
