Why Costco Stays Open on MLK Day
Costco observes only a limited number of federal holidays as closures, such as New Year’s Day, Easter, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Martin Luther King Jr. Day is not on that list, which means stores operate as a normal business day. Unlike federal offices, banks, or postal services that close on this holiday, Costco treats MLK Day as an opportunity to serve members who are off work and may want to complete errands, buy groceries, or purchase seasonal items. Keeping the stores open allows both the company and members to maintain consistent schedules and ensures access to products without disruption.
Operating on MLK Day also aligns with Costco’s philosophy of providing convenience and value for its members. By remaining open, Costco supports shopping flexibility for individuals, families, and small businesses who rely on its bulk products and warehouse discounts.
Costco Store Hours on Martin Luther King Jr. Day
Most Costco warehouses follow standard Monday operating hours on MLK Day, typically opening at 10:00 a.m. and closing around 8:30 p.m. However, hours may vary slightly depending on the location and regional policies. Some warehouses open earlier for business members, while others maintain consistent retail hours for all members. Departments such as pharmacy, optical, and gas stations might operate on slightly different schedules, so checking with your local warehouse ensures access to these services.
Maintaining regular hours on MLK Day allows members to plan their trips efficiently and take advantage of the full range of products and services offered at Costco, from fresh produce and meats to electronics, household goods, and seasonal items.
