Costco warehouses stay open on Juneteenth, regular hours expected

Costco’s U.S. warehouses stayed open on Juneteenth, turning the day into a staffing and traffic question more than a holiday shutdown. Most locations ran regular hours, so front-end assistants, stockers, forklift operators, meat and bakery teams, optical staff, and warehouse managers were dealing with a standard trading day rather than a company-wide closure.

That matters because Costco’s official holiday list does not include Juneteenth. The company says U.S. warehouses are closed only on New Year’s Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. Costco Customer Service also says warehouse hours can vary by location, and the Costco app shows location-specific details, including warehouse inventory, gasoline prices, contact information, hours, and adjusted holiday closures. For workers, that means local leadership still had to plan around the warehouse they were in, not just the national calendar.

The same caution applies to service areas inside the club. Costco says hours for gas station, pharmacy, optical, and other services can differ by warehouse, and any service with only a phone number follows the warehouse’s hours. That makes Juneteenth a day when the sales floor may be open on a normal schedule while individual counters need different coverage decisions. A warehouse could be busy enough to keep the front end moving while still having a shortened or shifted schedule at a department desk.

Juneteenth became a federal holiday in 2021, and in 2026 it fell on Friday, June 19, creating a three-day-weekend pattern that can change member traffic even when the warehouse itself stays open. The holiday marks June 19, 1865, when Union Major General Gordon Granger and 2,000 federal troops arrived in Galveston, Texas, to enforce the Emancipation Proclamation. In practice, that meant Costco employees were likely dealing with holiday-weekend shopping behavior while many federal offices and banks were closed.

For warehouse managers, the operational lesson was straightforward: Costco was open, but the floor still needed local checks on staffing, service hours, and member demand. For employees on the schedule, Juneteenth looked less like a closure and more like a regular day with a few moving parts that varied by building.
