BedtimePilotSleep planning · Free web tool
Enter when you plan to get into bed. The calculator adds your settling buffer, then shows wake-up choices for three through six cycles. Each result includes the planned duration so you can compare it with tomorrow’s commitments. The options are schedule estimates and do not guarantee how rested you will feel.
Sleep cycles vary from person to person and across the night. We use 90 minutes as a planning reference, not a measurement of your actual sleep stages.
Start with the time that is fixed for tomorrow. The calculator works backward or forward using your selected planning duration, the time you usually need to settle, and a separate wind-down window.
BedtimePilot uses adjustable cycle timing as a planning reference. Actual sleep architecture varies by person and night, and this tool does not measure sleep stages.
Results are planning estimates based on your times and adjustable settings. They do not detect sleep stages and are not medical advice. Do not reduce your sleep opportunity just to match a cycle count. Seek professional care for persistent sleepiness or sleep-health concerns.
