Using Bedtime Planner
- Enter the time you want to wake up.
- Choose your own sleep opportunity in hours and wind-down time in minutes.
- Calculate bedtime to see when to begin winding down and when to settle for sleep.
A practical example
With a 07:00 wake-up, eight hours of sleep opportunity and thirty minutes to wind down, the result is 22:30 for winding down and 23:00 for settling. Time to fall asleep is not separately estimated.
Why this planner avoids exact sleep-cycle predictions
Good to know
This planner subtracts your chosen sleep opportunity from your wake-up time. It does not predict exact sleep cycles or guarantee that a particular bedtime will make you refreshed. Your actual sleep needs and time to fall asleep vary.
