Wake Time Calculator

Determine optimal wake times from your sleep time

Optimal Wake Timing

Waking up at the right time in your sleep cycle can make a significant difference in how you feel throughout the day. This calculator helps you identify the best wake times based on when you went to sleep.

The calculator accounts for:

  • Time to fall asleep (approximately 15 minutes)
  • Complete sleep cycles (90 minutes each)
  • Light sleep phases for easier waking

By waking during a light sleep phase, you'll feel more alert and refreshed compared to being jolted awake during deep sleep stages.
