Wake Time Calculator
Discover the best times to wake up based on your bedtime. Our calculator helps you avoid waking up in the middle of a sleep cycle so you feel energized, not groggy.
How the Wake Time Calculator Works
Enter your planned bedtime, and our wake time calculator will show you the optimal times to wake up. By adding 15 minutes for falling asleep and then calculating in 90-minute increments (sleep cycles), we ensure you wake up at the lightest stage of sleep.
Why Wake Time Matters
Waking up in the middle of deep sleep or REM sleep can leave you feeling disoriented and tired, even if you've slept for 8+ hours. This phenomenon is called sleep inertia. By timing your alarm to coincide with the end of a sleep cycle, you wake up during light sleep when your body is naturally closer to consciousness.
