Costco will close all of its US warehouses for two full days in 2026, giving shoppers two dates when they will not be able to visit its stores. The closures apply nationwide, although individual warehouses may also have reduced opening hours around certain dates.
Costco Will Close on Thanksgiving
The first full-day closure will take place on Thanksgiving Day. Costco closes its US warehouses on Thanksgiving each year, meaning shoppers will need to complete their purchases before the holiday if they need goods from the retailer that day.
The closure applies across Costco’s US warehouse network.
Christmas Day Will Bring a Second Closure
The second full-day shutdown will come on Christmas Day. Costco traditionally closes its warehouses on December 25, giving employees the day off while stores remain closed to customers.
Together, the Thanksgiving and Christmas closures account for 48 hours when Costco’s US stores will not open.
Costco Closes on Several Other Holidays
The two dates are not the only holidays when Costco warehouses close. The retailer also closes its stores on New Year’s Day, Easter Sunday, Memorial Day, Independence Day and Labor Day.
These closures form part of Costco’s regular holiday schedule.
Store Hours Can Also Be Shorter Before Holidays
A holiday does not always mean a full-day closure. Costco typically operates reduced hours ahead of certain holidays.
Christmas Eve, for example, can have shorter opening hours than a normal trading day. Shoppers planning a visit around a holiday should therefore check the opening hours for their individual warehouse.
Costco Has More Than 600 US Stores
Costco currently operates more than 600 warehouses across the United States. Opening hours can vary between locations, so shoppers should use Costco’s Warehouse Locator to check the schedule for their nearest store.
This is particularly useful around holidays, when opening times can differ from the regular schedule.
Shoppers Should Plan Around the Closures
The Thanksgiving and Christmas closures mean Costco customers will need to plan ahead if they rely on the retailer for groceries, household supplies or other purchases.
Both closures are full-day shutdowns, while other dates may involve either a complete closure or shorter trading hours. Checking the local warehouse schedule before travelling can help shoppers avoid arriving when their Costco is closed.
