Costco Holiday Hours 2026: These are the Days Costco Is Closed

Planning a Costco run around a holiday? Check the calendar before you grab your shopping list and head to the warehouse.

Unlike many major retailers that stay open for most holidays, Costco closes its U.S. warehouses several times throughout the year. In 2026, Costco warehouses are closed for seven major holidays.

Here are the Costco holiday closures you need to know for 2026.

Is Costco Open on Holidays?

Costco is open on many holidays, but there are seven days when U.S. Costco warehouses are closed:

• New Year’s Day
• Easter Sunday
• Memorial Day
• Independence Day
• Labor Day
• Thanksgiving Day
• Christmas Day

That means if you’re planning a Costco trip around one of these holidays, you’ll need to shop before the holiday or wait until the warehouse reopens.

Christmas Eve is not included on Costco’s list of U.S. warehouse holiday closures. However, holiday hours can differ from regular warehouse hours.

If you’re planning a December 24 Costco run, check your local warehouse hours before leaving home.

New Year’s Eve is also not one of Costco’s seven listed U.S. warehouse closure days.

However, hours can vary by warehouse, particularly around holidays, so it’s best to check your specific location before heading out.

Is Costco Open on Presidents Day?

Presidents Day is not on Costco’s list of warehouse closures, so Costco warehouses are generally open.

Your local warehouse’s hours can vary, so check the location before making a special trip.

Is Costco Open on Martin Luther King Jr. Day?

Martin Luther King Jr. Day is not one of Costco’s listed U.S. warehouse closures. Costco warehouses are generally open.

Juneteenth is not included on Costco’s list of U.S. warehouse closures, so Costco warehouses are generally open.

Costco is closed on Thanksgiving Day, but warehouses reopen after the holiday. Since hours can vary by location, check your local warehouse before heading out.

Are Costco Gas Stations Open When Costco Is Closed?

Don’t assume that your Costco gas station follows the exact same schedule as the warehouse.

Costco says hours for warehouse services, including its gas stations, can be found by looking up the individual warehouse and checking its Store Details. Hours can vary by location, so check your local Costco before making a trip just for gas.

What About the Costco Pharmacy, Optical Department and Other Services?

Hours for services inside or associated with Costco can differ from regular warehouse hours.

Costco recommends looking up your specific warehouse and checking Store Details for hours for services such as the gas station, pharmacy and optical department.

This is especially important around holidays when schedules may change.

How to Check Your Local Costco’s Holiday Hours

The easiest way to confirm whether your Costco is open is to use Costco’s warehouse locator. Search by city, state or ZIP code and select your warehouse to see its current hours and upcoming holiday closures.

Costco also provides warehouse information through the Costco app.

Because hours can vary by warehouse, it’s a good idea to check before leaving home—especially on Christmas Eve, New Year’s Eve and the days surrounding major holidays.

Plan Your Costco Run Before the Holiday

Costco’s holiday closures are fairly easy to remember once you know the list: New Year’s Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

The bigger issue is remembering the closure before you pull into an empty Costco parking lot.

If a holiday weekend is coming up, I like to get my Costco run done early. The days leading up to major holidays can get busy, and popular seasonal foods and entertaining essentials may sell out.

So before your next holiday Costco run, check the calendar—and your local warehouse hours—before you go.
