Sleep time planner
Suggest 4, 5, or 6 cycles around a wake time or bedtime. Default fall-asleep buffer is 14 minutes and is editable.
Planning utility only. It does not diagnose sleep issues or give medical advice.
Limitations
The planner does not know caffeine, shift work, or disorders. If sleep is a health concern, speak with a clinician. This page only arithmetic.
Questions
Is this medical advice?
No. It is a scheduling sketch using 90-minute cycles and an optional fall-asleep buffer.
Why 90 minutes?
Many popular planners use 90-minute cycle assumptions. Actual sleep architecture varies by person and is not measured here.
