Is Costco Open Today? Holiday Hours & Tips

Wondering “is Costco open today” before you jump in the car? You’re not alone—around federal holidays (especially Martin Luther King Jr. Day) traffic to this question jumps as people scramble to plan grocery runs or bulk shopping. Here I’ll give a clear answer, explain why this is trending now, and walk through related questions like “is UPS open on MLK Day,” “are banks open today,” “is FedEx open on MLK Day,” and “is the stock market open today.” Read on for real-world tips, a quick comparison table, and what to check before you go.

Quick answer: Is Costco open today?

Short version: most Costco warehouses operate on regular hours on many federal holidays, but hours can vary by location and by the specific holiday. If today is MLK Day, many Costco locations remain open with normal or slightly reduced hours—but it’s best to check your local warehouse first. You can confirm with the Costco official site or call your nearby warehouse.

Why this question is trending (and who’s searching)

Two things converge: a federal holiday (MLK Day) and the normal weekend/weekday planning rhythm. People—especially busy parents, budget shoppers and commuters—want to know whether they can get essentials without a detour. In my experience, search volume spikes when a holiday falls midweek or on a Monday, because it affects bank schedules, shipping, and market hours all at once.

Emotional drivers and timing context

Mostly practical anxiety: folks want to avoid wasted trips. There’s also curiosity—will delivery and banking services run on the holiday? That drives related searches like “are banks open today” and “is the stock market open today.” The urgency: plan errands now, not tomorrow.

Costco hours: what to expect on MLK Day and similar holidays

Costco does not publish a single national holiday schedule that overrides local warehouse decisions. Generally:

• Many warehouses stay open on MLK Day with regular or slightly reduced hours.
• Major holidays like Thanksgiving and Christmas Day are typically closed.
• Holiday hours can vary by region, especially near city centers or areas with special restrictions.

Pro tip: check the Costco warehouse page for your nearest location on the Costco warehouse locator or call the store—simple, fast, reliable.

Other services and schedules (what else you should check)

Is UPS open on MLK Day?

UPS typically operates on a holiday schedule that may offer limited delivery or pickup services on federal holidays. For a definitive answer for the day in question, see the UPS holiday schedule. In practice, residential deliveries may be affected while some UPS Customer Centers remain open for essential pickups.

Is FedEx open on MLK Day?

FedEx has its own holiday rules: certain ground and express services can be limited on federal holidays. Many FedEx locations offer drop-off and limited retail hours, but scheduled pickups or some delivery services might be paused. Check the FedEx holiday guide on their website or call your local FedEx location for the fastest confirmation.

Are banks open today?

Most banks observe federal holidays—if MLK Day is the holiday in question, many branch lobbies will be closed and ATMs will be available as usual. Online and mobile banking still work. For official federal holiday listings that banks often follow, consult the Office of Personnel Management federal holidays page.

Is the stock market open today?

The New York Stock Exchange and NASDAQ close for certain federal holidays. To see if “the stock market is open today,” reference the exchange calendar—markets are typically closed on MLK Day. Confirm with the NYSE holiday calendar before making time-sensitive trades.

Real-world examples and reader stories

I once drove 15 minutes to an early-morning Costco only to find a temporary reduced schedule after a holiday weekend—annoying but avoidable. What I’ve noticed is customers who call ahead or quickly check the warehouse page save time and frustration. Another reader shared that UPS held a Saturday pickup due to holiday service changes—good to know if you’re expecting a time-sensitive package.

Practical takeaways: what to do right now

• Check your local Costco hours on the Costco warehouse locator before you go.
• If you need a package fast, verify UPS or FedEx schedules online—don’t assume normal delivery.
• Plan banking tasks around branch closures; use online banking for transfers and deposits.
• If you trade stocks, confirm market hours via the NYSE or your broker.
• Call ahead if you’re arranging big purchases (furniture, tires, optical) that may have separate service hours.

What to do if Costco is closed

If your nearby Costco is closed, consider alternatives: local big-box stores, warehouse competitors, or online ordering (Costco.com offers many items with shipping). Also check whether the optical clinic or gas station at that Costco location is operating on a different schedule—services sometimes differ.

Final thoughts

When the question “is Costco open today” pops up, it’s usually part of a larger planning problem: coordinating errands, deliveries and financial tasks around a holiday. The fastest route to the right answer is a quick online check or phone call to your local warehouse, plus checking UPS/FedEx and bank schedules if those services matter to you. Plan a little and you’ll avoid the wasted trip—and maybe get home in time for something better.
