Sleepy Time Bedtime Calculator

Wake up rested by going to bed at the right time.

Sleepy Time is a simple bedtime calculator. Tell it when you need to wake up, how many hours of sleep you want, and how long it usually takes you to fall asleep. It works backwards and shows you exactly when to get into bed, and the time you'll be asleep by.

Then let it remind you. Sleepy Time can send a notification every night when it's time to head to bed, and another when it's time to put down the coffee.

HOW IT WORKS
• Set your wake-up time
• Choose how many hours of sleep you want: 7, 8, 7.5, whatever works for you
• Add your unwind time, the minutes it takes you to drift off once you're in bed
• See your bedtime instantly, along with the time you'll be sleeping by

FEATURES
• Backwards bedtime calculator that updates as you type
• Nightly bedtime reminder
• Caffeine cutoff reminder, set 6 hours before your bedtime
• Remembers your settings, so tomorrow takes one glance
• Simple and private: no account or sign-up required

Feeling run down? Bump your sleep hours up. Take a while to fall asleep? Increase your unwind time. Keep adjusting until you land on a bedtime that fits your life.

SLEEP TIPS
• Your bedtime is when you get into bed, not when you fall asleep. Use your unwind time to read a book instead of scrolling. Light from screens can delay melatonin, the hormone that tells your body it's time to sleep.
• Life gets busy. Turn on the bedtime reminder so the evening doesn't get away from you.
• Watch the clock on caffeine. A 2013 study in the Journal of Clinical Sleep Medicine found that caffeine taken even 6 hours before bed noticeably disrupted sleep. That's why Sleepy Time's caffeine reminder goes off 6 hours before your bedtime.
• Shifting to an earlier schedule? Some people find melatonin helpful, taken about an hour before bed, while their body adjusts. Check with your doctor or pharmacist before starting any supplement.
• Consistency matters. Going to bed and waking up at the same time every day, weekends included, helps your body keep a steady rhythm.

Sleepy Time is a planning tool. It is not intended to diagnose or treat any sleep condition.
