When to use this post office guide

Best for users asking whether there is mail, whether post offices are closed, or which holiday page explains service impact.

What this category covers

The category includes holidays with mail or post office impact in the page data. U.S. pages may reference USPS context, while non-U.S. pages should use the local postal or public-service wording only after it is validated.

What this category does not replace

These pages explain holiday-level schedule context. They do not replace carrier tracking, local branch hours, or private courier notices, which can change by location and service type.
