A sleep diary records what happened during the night and how the next day felt. Estimates are acceptable; repeatedly checking the clock to make the diary precise can make the record more burdensome than useful.

Work through these questions: 10:45 p.m.

Fictional example. A reader estimates sleep onset rather than timing each waking. Her record shows time in bed and perceived rest as separate fields, preserving uncertainty instead of treating both as measured sleep duration.

Use several nights without inventing sleep time

Copy one row per night. Bedtime is not sleep onset, and final waking is not always the time you leave bed. Enter an estimate rather than a false exact value when needed. Review timing, interruptions, and daytime function together; this diary does not score sleep quality or diagnose a sleep disorder.
