Email is the fastest route: hello@freemuseumdays.com. We read everything; corrections get priority.
This is the email we most want. Free-day calendars change monthly, and a reader who just hit a closed ticket window knows before we do. Include the institution, what our page says, and — ideally — a link to the official page that says otherwise. Verified corrections ship in the next data update, and every entry's "last checked" date resets when it does.
If you run an institution or program listed here and something is wrong — or your free days aren't listed and you'd like them to be — email with a link to your official schedule page. We only publish what an official page confirms, so that link is the whole requirement.
Press, partnership and advertising questions go to the same address. We don't accept payment for placement in the free-day listings — that would defeat the point of the site.
