How it works
Enter the requested values, check the units, then run the Sleep Consistency Calculator for a copyable informational estimate.
The tool works by arithmetic mean and range only; it does not assess sleep quality or disorders. The result is a general estimate that cannot account for every individual factor and does not replace a clinician. Inputs stay in the browser.
Examples
Practical example
7, 8, and 7 hours average 7.33 hours with a one-hour range.
