Feedback and corrections
For a date or holiday correction, include the page URL, the date shown, the expected value, and the official source you are comparing against.
For calculator feedback, include the input dates, selected options, and the result you expected. That information makes it easier to reproduce the calculation and check whether the issue is a data problem, a method question, or a different business calendar assumption.

Response scope
We can review calendar data questions, page errors, broken links, unclear wording, and calculator behavior. We cannot review private contracts, payroll rules, tax filings, or legal deadlines. For those topics, use the site as a planning aid and check the official source or advisor that applies to your situation.
