Good sleep is essential for health, energy, and productivity. Our Sleep Calculator helps you find the perfect bedtime and wake-up time based on sleep cycles. This ensures you wake up feeling refreshed rather than groggy.
How the Sleep Calculator Works

Why Sleep Cycles Matter?
Each sleep cycle lasts about 90 minutes and includes light sleep, deep sleep, and REM sleep. Waking up in the wrong phase can cause grogginess, while waking at the right time leaves you refreshed.
