Planning a shopping trip and wondering what time Costco opens or closes? Costco hours depend on the day of the week, your membership type, and the warehouse you visit. Many U.S. locations open at 10:00 AM for Gold Star and Business members on weekdays, while Executive members can begin shopping earlier.
Weekend schedules are different, and Costco pharmacies, gas stations, and other services may operate outside regular warehouse hours. Holiday closures can also affect your plans.
This guide covers Costco’s verified 2026 warehouse hours, Executive member early shopping, Saturday and Sunday schedules, holiday closures, and how to confirm the correct operating hours for your nearest location.
Quick Answer
Costco warehouses commonly open at 10:00 AM Monday through Friday, 9:30 AM Saturday, and 10:00 AM Sunday for Gold Star and Business members. Closing times at several verified U.S. locations are 8:30 PM on weekdays, 7:00 PM on Saturday, and 6:00 PM on Sunday. Executive members have earlier opening times at eligible warehouses, beginning at 9:00 AM daily. Hours can vary by location, so confirm your warehouse’s current schedule before visiting.

What Time Does Costco Open and Close?
Costco uses different opening times depending on membership level at warehouses offering Executive member early shopping. Closing times may also differ between locations.
Costco Monday Through Friday Hours
At the Kirkland, Washington; Fort Worth, Texas; and Harrisburg, Pennsylvania warehouses, the posted weekday schedule is:
- Executive members: 9:00 AM–8:30 PM
- Gold Star members: 10:00 AM–8:30 PM
- Business members: 10:00 AM–8:30 PM
This gives Executive members an additional hour of morning shopping at these locations.
Costco Saturday Hours
The same warehouses list Saturday shopping hours as:
- Executive members: 9:00 AM–7:00 PM
- Gold Star members: 9:30 AM–7:00 PM
- Business members: 9:30 AM–7:00 PM
Saturday opening times are earlier than regular weekday opening times for Gold Star and Business members at these locations.
Costco Sunday Hours
The checked warehouses list Sunday hours as:
- Executive members: 9:00 AM–6:00 PM
- Gold Star members: 10:00 AM–6:00 PM
- Business members: 10:00 AM–6:00 PM
Sunday closing is earlier than weekday closing at these warehouses.
Costco Hours by Day
The following schedule is published for multiple verified U.S. Costco warehouses.
| Day | Executive Member Hours | Gold Star & Business Member Hours |
|---|---|---|
| Monday | 9:00 AM–8:30 PM | 10:00 AM–8:30 PM |
| Tuesday | 9:00 AM–8:30 PM | 10:00 AM–8:30 PM |
| Wednesday | 9:00 AM–8:30 PM | 10:00 AM–8:30 PM |
| Thursday | 9:00 AM–8:30 PM | 10:00 AM–8:30 PM |
| Friday | 9:00 AM–8:30 PM | 10:00 AM–8:30 PM |
| Saturday | 9:00 AM–7:00 PM | 9:30 AM–7:00 PM |
| Sunday | 9:00 AM–6:00 PM | 10:00 AM–6:00 PM |
These are confirmed location schedules rather than a universal nationwide timetable.
Does Costco Open Early for Executive Members?
Yes. Costco introduced exclusive earlier shopping hours for Executive members beginning June 30, 2025, with availability depending on the warehouse.
At several verified U.S. locations, Executive members can enter at 9:00 AM every day.
Executive vs. Gold Star Member Hours
The main difference is the opening time.
| Day | Executive Opening | Gold Star & Business Opening |
|---|---|---|
| Monday–Friday | 9:00 AM | 10:00 AM |
| Saturday | 9:00 AM | 9:30 AM |
| Sunday | 9:00 AM | 10:00 AM |
These differences are confirmed on the selected warehouse pages reviewed for this guide.
Executive early shopping is not the same as an earlier opening time for every membership level. Check your location’s posted membership schedule before arriving.
Do Costco Hours Vary by Location?
Yes. Costco’s official customer service information states that warehouse hours can differ slightly by location.
The distinction becomes particularly important when checking pharmacy, gas station, tire center, or other department hours.
Verified Costco Warehouse Hours by Location
The following information was checked against four official Costco warehouse pages on October 23, 2026.
| Warehouse | Gold Star & Business Weekdays | Saturday | Sunday |
|---|---|---|---|
| Kirkland, Washington | 10:00 AM–8:30 PM | 9:30 AM–7:00 PM | 10:00 AM–6:00 PM |
| Independence, Missouri | 10:00 AM–8:30 PM | 9:30 AM–7:00 PM | 10:00 AM–6:00 PM |
| Harrisburg, Pennsylvania | 10:00 AM–8:30 PM | 9:30 AM–7:00 PM | 10:00 AM–6:00 PM |
| Fort Worth, Texas | 10:00 AM–8:30 PM | 9:30 AM–7:00 PM | 10:00 AM–6:00 PM |
These four warehouses share the same general shopping schedule. However, matching hours at these locations do not establish that every U.S. Costco follows identical times.
Costco Gas Station Hours
Costco gas stations may open before their attached warehouses and remain open after warehouse shopping has ended.
For example, Costco’s official listings for the Fort Worth, Texas, and Harrisburg, Pennsylvania warehouses provide the following gasoline hours:
| Day | Gas Station Hours |
|---|---|
| Monday–Friday | 6:00 AM–10:00 PM |
| Saturday | 6:00 AM–8:30 PM |
| Sunday | 6:00 AM–7:30 PM |
These times are specific to the two checked locations.
Does Costco Gas Open Before the Store?
Yes, at the verified Fort Worth and Harrisburg warehouses, gas stations open at 6:00 AM on weekdays, before regular warehouse shopping begins.
Do not assume every Costco gas station uses the same schedule. Select the gas station section on your local warehouse page for accurate opening and closing times.
Costco Pharmacy Hours
Costco pharmacy hours are separate from standard warehouse shopping hours.
For example, the King of Prussia, Pennsylvania, warehouse publishes the following pharmacy schedule:
| Day | Pharmacy Hours |
|---|---|
| Monday–Friday | 9:00 AM–7:00 PM |
| Saturday | 9:00 AM–6:00 PM |
| Sunday | Closed |
The Fort Worth, Texas, pharmacy lists longer weekday service hours, ending at 8:30 PM, with Saturday hours ending at 7:00 PM and Sunday listed as closed.
This demonstrates why warehouse closing times should not be used to determine pharmacy availability.
Does Costco Pharmacy Close for Lunch?
Some Costco pharmacies may temporarily close when only one pharmacist is on duty.
The checked pharmacy listings explain that a 30-minute closure may occur between 1:30 PM and 2:30 PM under those circumstances.
This is a conditional service interruption, not a guaranteed daily lunch closure.
Is Costco Pharmacy Open on Sunday?
The checked pharmacies in King of Prussia, Fort Worth, and Harrisburg list Sunday as closed. However, individual pharmacy schedules should be verified rather than assuming the same rule applies nationwide.
Costco Tire Center, Optical, and Food Court Hours
Costco warehouses may provide several services with operating schedules that require separate verification.
Costco Tire Center Hours
Costco’s Fort Worth and Harrisburg warehouse pages state that tire center operating hours follow the warehouse’s shopping schedule for Executive, Gold Star, and Business members.
Both locations also recommend appointments for tire services.
Other warehouses may have different department arrangements, so verify your local tire center schedule before visiting.
Costco Optical Hours
Costco offers optical services at selected warehouses. The official warehouse finder identifies locations with optical departments, while individual warehouse information provides contact details and available hours.
Do not assume the optical department opens when the main warehouse opens.
Costco Food Court Hours
Costco’s warehouse locator identifies locations with food courts and provides department contact information.
Food court availability should be checked at the specific warehouse, particularly when visiting near opening or closing time.
The main warehouse schedule does not independently confirm a food court’s complete serving hours.
Costco Holiday Hours 2026
Costco officially lists seven annual holidays when its U.S. warehouses are closed.
These closures are important because normal weekday or weekend schedules do not apply on those dates.
Costco Holiday Schedule for 2026
| Holiday | Date in 2026 | Warehouse Status |
|---|---|---|
| New Year’s Day | Thursday, January 1 | Closed |
| Easter Sunday | Sunday, April 5 | Closed |
| Memorial Day | Monday, May 25 | Closed |
| Independence Day | Saturday, July 4 | Closed |
| Labor Day | Monday, September 7 | Closed |
| Thanksgiving Day | Thursday, November 26 | Closed |
| Christmas Day | Friday, December 25 | Closed |
This table reflects Costco’s officially published U.S. warehouse closure policy.
Other holidays may have adjusted operating hours. Costco’s location finder provides upcoming holiday closures and schedule changes.
Is Costco Open on Thanksgiving?
No. Costco lists Thanksgiving Day as a closure holiday for U.S. warehouses.
In 2026, Thanksgiving falls on Thursday, November 26.
Is Costco Open on Christmas Day?
No. U.S. Costco warehouses are officially closed on Christmas Day, Friday, December 25, 2026.
Christmas Eve hours are not covered by the same confirmed closure policy, so check your individual warehouse for its December 24 schedule.
Is Costco Open on New Year’s Day?
No. Costco’s official U.S. holiday policy lists January 1 as a warehouse closure day.
New Year’s Eve hours may differ from standard operating times and require location-specific verification.
Is Costco Open on Easter Sunday?
No. Easter Sunday is included in Costco’s official list of U.S. warehouse closures.
For 2026, Easter Sunday fell on April 5.
Is Costco Open on Memorial Day and Labor Day?
No. Costco identifies both Memorial Day and Labor Day as U.S. warehouse closure holidays.
Memorial Day fell on May 25, 2026, and Labor Day fell on September 7, 2026.
Is Costco Open on Other Federal Holidays?
Costco’s official closure list does not include every federal holiday.
For holidays such as Martin Luther King Jr. Day, Presidents’ Day, Juneteenth, Columbus Day, and Veterans Day, the published seven-holiday closure policy alone does not confirm every location’s exact operating schedule.
A specific warehouse may provide an updated holiday notice through its official listing.
Checking the location directly is especially useful when a holiday falls near a weekend or a scheduled shopping trip.
How to Check Costco Hours Near You
The most reliable way to find your local Costco opening time is through Costco’s official warehouse information.
- Open Costco’s official website and select Find a Warehouse.
- Search using your city, state, or ZIP code.
- Select the warehouse you plan to visit.
- Review Executive member and Gold Star/Business member hours separately.
- Check warehouse services and any upcoming holiday closures.
- Call the listed warehouse phone number if you need confirmation about a special schedule.
Google Maps can provide another reference for general store hours, but the official Costco location page is preferable for membership-specific opening times and department schedules.
Can You Check Costco Hours in the Costco App?
Yes. Costco’s official customer service guidance confirms that its mobile app can be used to find warehouse locations and operating hours.
The app is available for supported iOS and Android devices.
When checking hours, select your intended warehouse instead of relying on information for a previously selected location.
This is particularly important for Executive early shopping and changes during holidays.
