What is the Nap Time Calculator?

The Nap Time Calculator helps you plan short or full-cycle naps to maximize alertness and restfulness. Using typical nap durations of ~20 minutes for a quick boost or ~90 minutes for a complete sleep cycle, this tool calculates either the optimal start time if you want to wake up refreshed or the optimal wake-up time if you start your nap at a certain hour. By aligning naps with natural sleep cycles, you can avoid grogginess and improve cognitive performance.

How to Use:

1. Enter Current Time or Desired Nap Start Time: Input either the time you plan to start your nap or the time you want to wake up.
2. Select Calculation Mode: Choose “I want to Wake Up at” to get suggested nap start times, or “I want to Start Nap at” to see suggested wake-up times.
3. Click “Calculate”: The calculator generates short (~20 min) and full-cycle (~90 min) nap options.
4. Review Result: Use the suggested times to plan naps efficiently, depending on whether you need a quick refresh or a full rest cycle.
