Sleep Calculator: Bedtime Plan

Plan your bedtime, wake-up time, naps, and nightly routine with a simple sleep calculator built for everyday scheduling.

Sleep Calculator: Bedtime Plan helps you work backward from a wake-up time, calculate a bedtime from your target sleep duration, or start with a bedtime and see practical wake-up options. Add a wind-down buffer, save routines for different days, and use gentle reminders to stay consistent.

SLEEP CALCULATOR

Choose when you need to wake up and quickly calculate when to be in bed based on your target sleep duration and wind-down time.

You can also start with a bedtime and calculate useful wake-up options. It is a fast way to answer questions like:

• What time should I go to bed?
• What time should I wake up?
• How much time is left until bedtime?
• What bedtime fits my morning schedule?

BEDTIME & WAKE-UP PLANNER

Create a sleep schedule that fits your day instead of relying on one fixed routine.

Adjust:
• Wake-up time
• Target sleep duration
• Wind-down time
• Bedtime or lights-out target
• 12-hour or 24-hour time format

The planner automatically handles schedules that cross midnight.

SAVE SLEEP ROUTINES

Keep different schedules ready for the days you actually live.

Save routines for:
• Workdays
• Weekends
• Early starts
• Classes
• Travel days
• Other custom schedules

Reuse a saved routine in the planner whenever you need it.

BEDTIME REMINDERS

Set recurring bedtime reminders for selected days of the week so you can start winding down before your planned bedtime.

Choose your reminder time and lead time, then let the app help you keep your routine visible without replacing your normal alarm clock.

NAP PLANNER

Need a short rest during the day? Use the nap planner to set a simple nap timer without changing your regular sleep schedule.

WIND-DOWN CHECKLIST

Create a short local checklist for the last part of your evening. Use it for simple tasks such as preparing clothes, dimming lights, charging your phone, or setting your alarm.

OPTIONAL SLEEP-CYCLE ESTIMATES

The app can also show approximate sleep-cycle timing as a secondary planning reference.

Sleep cycles are not identical for everyone, and real sleep stages cannot be determined from a simple time calculator. Cycle suggestions are estimates only and should not be treated as measurements of your actual sleep.

PRIVATE, SIMPLE & ON-DEVICE

Core sleep planning features work locally on your device.

• No account required
• No cloud setup required
• Saved schedules stay on your device
• Fast access to your planner, reminders, naps, and routines
