Costco's holiday closures for 2026 and 2027
“Our U.S. warehouses are closed the following days: New Year’s Day Easter Sunday Memorial Day Independence Day Labor Day Thanksgiving Day Christmas Day”
The list names the days and no year, so the dates below are worked out from each day's rule (Easter by the Gregorian computus). Costco's list names Independence Day, July 4. It does not say anything about observed days, so we do not say Costco closes on July 3, 2026 or July 5, 2027. July 4 is a Saturday in 2026 and a Sunday in 2027.
