Use one clear path when results or guidance need correction.

The calculator and guides improve when you report precise findings. This page explains what we need from a report and how we review what you send.

When to write

Wrong numbers from specific dates.
Edge-case behavior that contradicts common date rules.
Ambiguous phrasing that could lead to misuse.
Accessibility issues or broken links.

How to report

Include the calculator mode.
Include every date value used.
Include browser version or device if a rendering issue appeared.
Mention the expected result and what changed in your workflow.

Review process

Reports are reviewed in sequence: reproducibility, result traceability, guidance updates, and publishing. If the issue is confirmed, we update the page and record the correction status in the editorial review list.

Scope

This policy covers calculator logic questions, guide correctness, link quality, and accessibility fixes. It does not provide legal, payroll, immigration, or policy adjudication advice.
