How the Bedtime Calculator Actually Works

The Secret Formula

Our calculator considers these key factors:

Your wake-up time: When you need to be alert and energized
Sleep cycles: 90-minute cycles that determine sleep quality
Sleep onset time: How long it takes you to fall asleep (typically 10-20 minutes)
Age factor: Sleep efficiency changes throughout life
Chronotype: Whether you're naturally a morning person or night owl

      Did You Know? The average person takes 14 minutes to fall asleep. Our calculator factors this in automatically!

Time your bedtime so you complete 5-6 full cycles before waking up.
