With the Free Online Sleep & Bedtime Calculator, you can create a personalized bedtime and evening schedule based on the time you want to wake up and how much sleep you would like to get.
Instead of simply showing a bedtime, the calculator works backward from your wake-up time and provides useful timing recommendations for your evening. These include when to go to bed, when you should ideally be asleep, when to start winding down, and approximate times for reducing fluids, finishing large meals, intense exercise and caffeine.
