Use this form for a wrong date, a broken calculator, a district calendar we should add, or a question about how we count.

We read every message. If you leave an email address, we reply from there; if not, a fix shows up on the page and in the corrections log. We do not answer legal, tax or immigration questions about your own situation, since this is a counting tool and not an advice service.

The form collects only what you type. The privacy page explains where messages go.
