((wake_up_time + 7) % 24) * 60Frequently asked
Why is the ideal nap time about 7 hours after waking?
Circadian rhythms naturally dip in the early afternoon, roughly 7–8 hours after waking, making it easier to fall asleep and get restorative rest.
How long should a power nap be?
10–20 minutes is ideal to boost alertness without entering deep sleep. Naps longer than 30 minutes can cause sleep inertia (grogginess).
Can I nap later in the day?
Napping too late (after 3–4 PM) can interfere with nighttime sleep. This calculator aims for the optimal early-afternoon window.
