Overview

• Monday, Sept. 1 is the federal holiday, with post offices closed, no regular USPS delivery, and major bank branches shuttered nationwide.
• UPS suspends pickup and delivery, most FedEx services pause, and only express/critical options operate; check local storefronts for modified hours.
• Most national restaurants, retailers and grocery chains are open with location‑specific hours, though Costco closes and some clubs run limited schedules.
• Cities adjust operations: in Philadelphia, SEPTA runs on a Sunday schedule and trash and recycling collections shift one day later.
• Arizona travelers get relief on I‑17 as new flex lanes open for the weekend and ADOT schedules no holiday closures or lane restrictions.
