Costco Store Hours: Standard Times, Holidays, And Closing Exceptions

Most standard Costco warehouses close at 8:30 PM Monday through Friday, at 6:00 PM or 7:00 PM on Saturdays, and at 6:00 PM or 7:00 PM on Sundays, though exact schedules depend heavily on your region. Standard weekday opening times kick off at 10:00 AM, while weekend hours typically start earlier at 9:30 AM on Saturdays and 10:00 AM on Sundays.

If you're planning a bulk run, checking the core schedule is only half the battle. Costco closes completely on major national holidays like Thanksgiving and Christmas, and auxiliary departments—such as the pharmacy, optical center, and gas station—often operate on entirely different timetables. Let's break down the exact operational rhythms so you don't pull up to locked gates.

Standard Costco Warehouse Hours

While localized traffic patterns and municipal laws can alter daily schedules, the vast majority of U.S. and Canadian warehouses adhere to a predictable baseline structure.

• Monday through Friday: 10:00 AM to 8:30 PM
• Saturday: 9:30 AM to 6:00 PM (or 7:00 PM at select locations)
• Sunday: 10:00 AM to 6:00 PM (or 7:00 PM at select locations)

These closing times are enforced strictly. Once the roll-up security doors start coming down or staff locks the entrance at closing time, late arrivals are turned away. If you walk in twenty minutes before closing, you have to move fast. Registers close promptly after the final shoppers exit.

Executive Member Early Entry Hours

If you hold an Executive Membership, you get access to exclusive early shopping hours at select warehouses.

• Monday through Friday: Entry begins at 9:00 AM (one hour before standard members)
• Saturday: Entry begins at 9:00 AM (thirty minutes before standard members)
• Sunday: Entry begins at 9:00 AM (one hour before standard members)

These early windows let you grab bulky items, fresh produce, and bakery goods before the main morning rush hits the warehouse floor. Keep in mind that not every regional market participates in early entry, so verify your home warehouse's policy via the official Costco Warehouse Locator.

Major Holidays: When Costco is Closed

Costco protects its employees' time off by closing all warehouses on seven major national holidays. If you show up on any of these days, the parking lots will be empty:

1. New Year's Day (January 1)
2. Easter Sunday (Date varies)
3. Memorial Day (Late May)
4. Independence Day (July 4)
5. Labor Day (First Monday in September)
6. Thanksgiving Day (Fourth Thursday in November)
7. Christmas Day (December 25)

On these days, all internal services—including the pharmacy, optical department, tire service center, and food court—remain completely shut down.

Holidays with Modified or Normal Hours

Unlike competitors that slash hours or open at bizarre times, Costco treats most minor or federal holidays as regular business days.

• Open with Regular Hours: Martin Luther King Jr. Day, Presidents' Day, Juneteenth, Veterans Day, and Indigenous Peoples' Day operate on standard weekday hours.
• Early Closures: On Christmas Eve and New Year's Eve, Costco typically opens early (around 8:30 AM) to accommodate last-minute shoppers, but closes its doors sharply at 5:00 PM.
• Black Friday: Costco opens on its standard Friday schedule rather than opening in the middle of the night. Deals are available, but you won't find chaotic midnight doorbusters.

Specialized Department Hours

The main warehouse doors aren't the only ones with specific schedules. If you are visiting Costco for gas, prescriptions, or tires, expect different operating windows.

Costco Gas Station Hours

Gas stations generally open earlier and close later than the main warehouse, making them convenient for early commuters or evening drivers.

• Monday through Friday: Usually open from 6:00 AM to 9:30 PM
• Weekends: Typically open from 6:00 AM to 7:00 PM
• Note: Gas stations close on the exact same major holidays as the warehouse (such as Thanksgiving and Christmas).

Costco Pharmacy and Optical Hours

Pharmacies run on independent schedules governed by state or provincial health regulations and pharmacist availability.

• Most pharmacies close earlier than the warehouse—often shutting down by 6:00 or 7:00 PM on weekdays.
• Many locations close their pharmacy counters entirely on Saturdays and Sundays, or operate with severely restricted morning-only hours.
• Optical departments follow a similar pattern, frequently closing an hour or two before the main warehouse registers lock up.

Costco Business Centers

If you live near a Costco Business Center (which caters heavily to commercial buyers, offices, and restaurants), note that they operate on entirely different timelines.

• They open much earlier, typically at 7:00 AM Monday through Saturday.
• They close earlier, usually shutting down by 6:00 PM on weekdays and 4:00 PM on Saturdays.
• Business Centers are closed on Sundays.

Common Mistakes When Timing Your Costco Trip

Shoppers frequently miscalculate their warehouse trips, leading to wasted fuel and locked doors. Avoid these common missteps:

• Assuming Sunday hours match Saturday: Saturdays usually give you an extra hour or half-hour in the evening compared to Sundays. Rushing in at 6:15 PM on a Sunday usually means hitting a locked door.
• Forgiving the pharmacy discrepancy: Just because the warehouse is open until 8:30 PM doesn't mean you can pick up a prescription at 8:00 PM. Always call the pharmacy line directly if you are arriving late.
• Shopping the day before a holiday blind: The day before Thanksgiving or Christmas Eve sees extreme congestion. Parking lots fill up hours before closing, and popular items run out. Shop at least 48 hours in advance of major holiday closures.
• Ignoring local bylaws: Certain municipal or provincial laws dictate retail hours. For example, some locations are restricted from opening early on Sundays due to local blue laws. Always cross-reference with the official Costco app for your specific zip code.

Frequently Asked Questions

Can I finish shopping if I am inside when Costco closes?

Yes, but you have very little time. Staff will make announcements starting fifteen minutes before closing. Once the final bell rings, cashiers will only ring up the items currently in your cart, and security will direct everyone straight to the registers and exit doors.

Are Costco food courts open after the store closes?

Food court access usually ends right as or slightly before the warehouse closes. If you plan to grab a hot dog or pizza on your way out, order before you get in line for the checkout registers.

Do Costco tire service centers have Sunday hours?

Most Costco Tire Service Centers are open Monday through Saturday, but many locations close entirely on Sundays or operate with reduced technician availability. Always call ahead if you need a flat repair or rotation on a weekend.

What is the least crowded time to visit Costco?

To avoid heavy weekend crowds, plan your trip between Tuesday and Thursday during mid-morning (10:30 AM to 11:30 AM) or during the final hour before closing on a weekday. Avoid Saturday afternoons entirely if you want to skip long checkout lines.
