BedtimePilotMethodology and sources · Planning principles
BedtimePilot separates published sleep guidance from product scheduling choices. The NHLBI explains sleep stages and changing cycles; the AASM and Sleep Research Society adult consensus recommends seven or more hours regularly. Neither source validates a specific alarm minute or the claim that waking at a cycle boundary guarantees feeling rested.
Use the NHLBI sleep-stage overview for biological context and the 2015 AASM/SRS consensus for adult duration guidance. The default wind-down and settling buffers are editable scheduling assumptions, not universal prescriptions. BedtimePilot has no medical endorsement from these organizations.
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.

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.

Keep tomorrow's wake-up goal fixed, compare the time available tonight, and allow separate settling and wind-down buffers. A plan remains an estimate even when its clock times are precise.
Questions
No. There are no sleep-stage measurements in this calculator.
