Best Sleep Schedule by Wake-Up Time: Bedtime Charts for Every Age
A quick-reference guide to your ideal sleep schedule — see exactly what time to go to bed and what time to wake up, by age and by sleep cycle, with worked examples for real routines.
🤖 AI Summary
Your ideal sleep schedule depends on your wake-up time, your age, and how many complete 90-minute sleep cycles you get. Most adults need 7-9 hours, which means going to bed between 9:00 PM and 11:15 PM for a 6:00-7:00 AM wake-up, plus roughly 15 minutes to actually fall asleep. Research in the European Heart Journal links a 10:00-11:00 PM sleep onset with the lowest cardiovascular risk. To build a stable routine, pick one wake-up time, count back 7-9 hours for bedtime, and shift by only 15 minutes a day if you need to change your current schedule. Use the wake up time calculator or bedtime calculator below for results matched to your exact schedule.
Most sleep advice stops at "get 7-9 hours." The real question is when those hours should fall. This guide gives you a direct, chart-based answer — how much sleep you need at your age, and the exact sleep times that work for your routine — without wading through the full science first. For the biology behind these numbers (circadian rhythm, melatonin, and why timing itself affects health), see our complete sleep timing science guide.
How Many Hours of Sleep Do You Need by Age?
Before picking a bedtime, you need your target sleep duration. The American Academy of Sleep Medicine and CDC guidelines below are the baseline every chart on this page is built from.
| Age Group | Recommended Sleep |
|---|---|
| Infants (4-12 months) | 12-16 hrs (with naps) |
| Toddlers (1-2 years) | 11-14 hrs (with naps) |
| Preschoolers (3-5 years) | 10-13 hrs (with naps) |
| School-age (6-12 years) | 9-12 hrs |
| Teens (13-18 years) | 8-10 hrs |
| Adults (18-64 years) | 7-9 hrs |
| Older adults (65+) | 7-8 hrs |
This is a quick-reference summary only — for the full breakdown of why sleep needs change with age and how to tell if you personally need more or less, see How Much Sleep Do I Need?
Bedtime Chart: What Time Should You Go to Bed?
Once you know your required wake-up time, working out when to sleep is simple math. Each row below assumes an adult target of 6-9 hours and adds the average 15-minute sleep latency (time it takes to actually fall asleep) automatically.
| Wake-Up Time | 9 hrs (6 cycles) | 7.5 hrs (5 cycles) | 6 hrs (4 cycles) |
|---|---|---|---|
| 5:00 AM | 7:45 PM | 9:15 PM | 10:45 PM |
| 6:00 AM | 8:45 PM | 10:15 PM | 11:45 PM |
| 6:30 AM | 9:15 PM | 10:45 PM | 12:15 AM |
| 7:00 AM | 9:45 PM | 11:15 PM | 12:45 AM |
| 7:30 AM | 10:15 PM | 11:45 PM | 1:15 AM |
| 8:00 AM | 10:45 PM | 12:15 AM | 1:45 AM |

How to Build Your Ideal Sleep Schedule in 4 Steps
- Pick a fixed wake-up time. Choose one wake-up time and keep it identical every day, including weekends — this is the anchor your whole schedule is built around.
- Count back 7-9 hours for bedtime. Subtract your target sleep duration from the wake-up time, then add roughly 15 minutes for sleep latency.
- Align to a full 90-minute cycle. Nudge bedtime 15-30 minutes earlier or later so total sleep time lands on a multiple of 90 minutes, avoiding a mid-cycle alarm.
- Shift gradually, 15 minutes a day. If your current bedtime is far from the target, move both bedtime and wake-up time by 15 minutes daily rather than jumping straight there.
Sleep Schedule Examples
🏢 The 9-to-5 Professional
Needs to be up at 6:30 AM. Ideal bedtime: 9:15 PM (9 hrs) or, more realistically, 10:45 PM for 7.5 hours across 5 complete cycles.
🎓 The Late-Night Student
Class starts at 9:00 AM, so wake-up is 7:30 AM. Studying until midnight leaves only 6 hours (4 cycles) — trimming study time to end by 10:15 PM restores a full 7.5 hours.
🌙 The Natural Night Owl
Falls asleep easily around midnight and wakes at 9:15 AM (9 hrs, 6 cycles). As long as this is consistent daily, it's a perfectly healthy sleep schedule for a late chronotype.
👩⚕️ The Rotating-Shift Worker
No single fixed bedtime is possible. Instead, the target becomes hitting a full 4-6 cycles (6-9 hrs) around each shift and using consistent light/dark cues to help the body adjust — see the jet lag calculator for timing light exposure.
Adjusting Your Schedule Gradually
Jumping from a midnight bedtime to a 9:30 PM bedtime overnight rarely works — your circadian rhythm resists sudden changes. Move bedtime and wake-up time by about 15 minutes each day in the direction you need. Most people reach a new stable schedule within 7-14 days. Getting outside for morning sunlight as soon as you wake helps reinforce the new timing faster, since light is the primary cue your body clock responds to.
Frequently Asked Questions
What time should I go to bed if I wake up at 6 AM?
For a 6:00 AM wake-up, most adults should be asleep by 9:00 PM (9 hours, 6 cycles), 10:30 PM (7.5 hours, 5 cycles), or midnight (6 hours, 4 cycles) at minimum. Add about 15 minutes before those times to allow for falling asleep.
Is it better to wake up early or sleep in?
Neither time is inherently healthier. What matters most is getting 7-9 hours consistently and waking at roughly the same time every day. Early risers and night owls can both be equally well-rested if their schedule is consistent and matches their natural chronotype.
How much sleep do I actually need for my age?
The American Academy of Sleep Medicine and CDC recommend 7 or more hours for adults 18-64, 8-10 hours for teens 13-18, 9-12 hours for children 6-12, and 10-13 hours for preschoolers 3-5, including naps.
What is the healthiest bedtime according to research?
A large cohort study published in the European Heart Journal found the lowest cardiovascular risk among people who fell asleep between 10:00 PM and 11:00 PM. Both earlier and later sleep onset were associated with higher risk, likely because they misalign with the body's natural circadian timing.
Can I catch up on lost sleep over the weekend?
Sleeping in occasionally can reduce short-term sleepiness, but it does not fully reverse the effects of a week of sleep debt and can create social jetlag by shifting your body clock. A steady schedule with the right amount of sleep each night is more effective than weekend catch-up sleep.
How do I fix an inconsistent sleep schedule?
Pick one target bedtime and wake-up time, then shift your current schedule toward it in 15-minute increments every day rather than all at once. Get morning sunlight right after waking and keep the new wake-up time fixed, even on days you sleep poorly, to lock in the new rhythm within one to two weeks.
