FAQ
What time should I wake up if I go to bed at 11 PM?+
It depends on how long it takes you to fall asleep and how many cycles you want to plan for. Use the calculator to compare 4, 5, and 6 estimated cycle options.
Is it better to wake up at the end of a sleep cycle?+
It can feel easier for some people, but sleep cycles are not perfectly fixed. Use cycle timing as a practical guide, not a guarantee.
Why do I wake up tired?+
Timing can matter, but so can sleep duration, stress, caffeine, light, noise, and sleep quality. Persistent problems deserve professional guidance.
What is a good wake-up time?+
A good wake-up time is one you can keep consistently while still leaving enough time for sleep. The calculator helps you compare options from your planned bedtime.
Should I use an alarm?+
An alarm is useful for commitments, but a consistent bedtime and wake-up time can make the alarm feel less abrupt over time.
Can I use this for naps?+
Yes, but use a shorter sleep goal. For naps, many people plan around 20 minutes or one full cycle instead of a full night of sleep.
