Seven-night sleep diary
Record a week of timing and perceived quality. The pattern is often more useful than trying to judge one unusual night.

Keep the record simple
Enter approximate times rather than chasing precision. For quality, use the same personal scale each morning: 1 means very poor and 5 means very good. A short note can capture a late meal, unusual noise, travel, exercise, or another context you want to remember.
Look for repeatable patterns
After seven nights, compare timing consistency with your own quality ratings. This diary does not estimate sleep stages or diagnose a condition. You can export the CSV for your own records or to help prepare for a conversation with a qualified professional.
