BedtimePilotBedtime planning · Free web tool
Getting into bed at 9 PM, with a 10-minute settling buffer and five 90-minute planning blocks, gives a 4:40 AM wake-up goal. The sleep target is 9:10 PM; wind-down begins at 8:15 PM with the default 45-minute window. Compare alternatives below and match tomorrow's obligations. These times do not predict actual sleep stages or guarantee a better wake-up.
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.
