Columbus Day on Monday, Oct. 12, 2026 brings closures for some federal-related services, while others continue operating. Reports agree that the stock market is open, but mail service and most banking operations are shut for the holiday.

CBS and other outlets note that the U.S. Postal Service does not run on federal holidays, so mail delivery and physical post office locations are closed. Banking practices vary by institution: many branches follow the holiday closure associated with the Federal Reserve, though some banks may keep select branches open while limiting certain services.

For shoppers, outlets provide guidance that major retailers, pharmacies, restaurants and similar businesses generally remain open during normal hours, including large store chains and warehouse retailers like Costco. Coverage also highlights that public schools are governed by local or state calendars, so schools may differ depending on district policies. Overall, most sources emphasize checking specific providers’ holiday hours for confirmation, especially for banking and other services that can vary by location.
