What Is MLK Day and Why Does It Matter?
Martin Luther King Jr. Day is a federal holiday observed on the third Monday of January every year. It celebrates the life and work of Dr. Martin Luther King Jr., a pioneer of the civil rights movement who advocated for racial equality and nonviolent resistance.
Although many government institutions and banks close in observance of MLK Day, retailers like Costco typically remain open. That’s because it’s not one of the “Big Seven” holidays that Costco closes for. Still, hours may vary based on location, and it pays to plan ahead.
Costco MLK Day Hours: What to Expect
Unlike more restrictive holidays like Thanksgiving or Christmas, Costco treats MLK Day like a regular weekday. The store is open to all members, and services such as the food court, gas station, pharmacy, and optical department are typically available as well.
Regular Warehouse Hours:
- Monday, January 19, 2026
- Opening Time: 10:00 AM
- Closing Time: 8:30 PM
Early Access for Executive Members:

Keep in mind that these are general hours, and individual store schedules may differ slightly. For instance, warehouses in urban areas like New York City, Chicago, or Seattle may have adjusted schedules due to local regulations or traffic patterns.
Services Available on Costco MLK Day Hours
Not only are Costco’s warehouses open, but many of its in-store services are also running. Here’s what you can expect:
1. Costco Gas Stations
Costco gas stations operate on regular schedules during MLK Day. Expect increased traffic in the late morning and early evening.
2. Costco Pharmacy
Most pharmacies inside Costco will be open. However, hours may be shorter than the warehouse hours.
3. Optical and Hearing Aid Centers
These services are available but may follow different hours from the main store. Scheduling appointments ahead of time is recommended.

Why Do Some People Think Costco Might Be Closed?
This confusion is pretty common, especially for newer members. Costco has a reputation for observing holidays seriously — even more than most big retailers. While other chains stay open nearly every day of the year, Costco closes on seven major holidays.
Here’s the official list of Costco’s holiday closures:
- New Year’s Day
- Easter Sunday
- Memorial Day
- Independence Day (July 4th)
- Labor Day
- Thanksgiving Day
- Christmas Day
Since MLK Day is not on this list, you can rest easy knowing that the store is open.
