Reporting a calculation issue
When support is available, include the page, calculation mode, time zone, date and the result you expected. A short example is usually more useful than a screenshot containing personal information. Do not include passwords, health records or another person’s private details.
Suggesting a content correction
Include the page URL, the sentence you are concerned about and a link to the original source when possible. We prioritize references from public health agencies and professional sleep organizations. See our methodology for the current approach.
