Costco Store, Pharmacy & Gas Hours in 2026

Costco runs on pretty specific schedules, depending on the service you need.

Most Costco warehouses are open Monday through Friday from 10:00 AM to 8:30 PM, Saturday from 9:30 AM to 7:00 PM, and Sunday from 10:00 AM to 6:00 PM.

But these hours can shift a bit depending on where you are.

Pharmacies and gas stations at Costco usually have their own hours. Gas stations tend to open earlier and close later, while pharmacy schedules are often a bit more limited.

Holidays, local rules, or even special events can shake up the usual hours, so it’s always smart to check ahead before heading out.

Typical Costco Store Hours

Most Costco warehouses stick to pretty standard hours, but there are differences between weekdays and weekends. Store hours typically run from 10:00 AM to 8:30 PM Monday through Friday.

Weekday Opening and Closing Times

From Monday to Friday, most Costco locations open at 10:00 AM and close at 8:30 PM.

That’s a solid 10.5 hours for shopping each weekday. The later closing time is nice if you’re stuck at work all day.

Some stores might tweak these times a little. It’s worth double-checking your local Costco’s schedule before making the trip.

Weekend Schedule Differences

Weekend hours are a bit different. Saturday hours usually run from 9:30 AM to 6:00 PM.

Sunday schedules can vary, but most warehouses open from 10:00 AM to 6:00 PM.

Weekend hours are shorter, so it can get a little more crowded. Saturday opens up half an hour earlier, which is handy for early birds.

Store Holiday Closures and Adjusted Hours

Costco shuts down completely on several big holidays: New Year’s Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas Day.

On some holidays, they don’t close all the way but may open late or shut the doors early. New Year’s Eve and Christmas Eve are good examples, except for shorter hours on those days.

These holiday hours aren’t always the same everywhere. Double-check your local warehouse’s holiday schedule online or on the Costco app if you’re unsure.

Pharmacy Operating Hours

Costco pharmacy hours are pretty consistent but don’t match the main store. Pharmacies are open from 10:00 AM to 7:00 PM Monday through Friday, but weekends are a bit different.

Standard Pharmacy Timings

Most Costco pharmacies open at 10:00 AM and close at 7:00 PM on weekdays.

Monday through Friday Hours:

• Opening Time: 10:00 AM
• Closing Time: 7:00 PM
• Total Service Hours: 9 hours daily

On Saturdays, pharmacies start an hour earlier at 9:00 AM but close at 6:00 PM.

Saturday Hours:

• Opening Time: 9:00 AM
• Closing Time: 6:00 PM

Most pharmacies are closed on Sundays, so don’t count on picking up a prescription then.

There’s usually a short lunch break, typically about 30 minutes between 1:30 PM and 2:00 PM—when the pharmacy shuts down for a bit.

Prescription Pick-Up and Drop-Off Hours

Prescription services run during all pharmacy hours. You can drop off new scripts, grab refills, or just pick up your meds whenever they’re open.

Available Services During Operating Hours:

• New prescription drop-off
• Prescription refill requests
• Medication pick-up
• Insurance verification
• Medication counseling

If you show up after hours, you’re out of luck—no pharmacy services outside the posted times. And if you’re dropping off a new prescription, try to arrive at least 15 minutes before closing.

Costco has online prescription management for refills and transfers, but you’ll still need to pick up in person during open hours.

Holiday Exceptions for Pharmacy

Pharmacies stay open on a lot of holidays when the main store does, but some holidays mean a full closure.

Holidays When Pharmacy Stays Open:

• Father’s Day and Mother’s Day
• Valentine’s Day
• Halloween
• Black Friday
• Christmas Eve
• New Year’s Eve
• Veterans Day
• Columbus Day

Holidays When Pharmacy Closes:

• New Year’s Day
• Easter Sunday
• Memorial Day
• Independence Day (July 4th)
• Labor Day
• Thanksgiving Day
• Christmas Day

Holiday hours can change based on location or state laws. Check with your local pharmacy if you’re not sure.

Some places might have shorter hours before a big holiday, or maybe stay open a bit later the day before a closure.

Costco Gas Station Hours

Costco gas stations have their own hours, usually opening earlier and closing later than the main store during the week. Weekends are shorter, and major holidays mean the pumps are closed.

Regular Gas Station Schedule

Most gas stations open somewhere between 5 AM and 9 AM on weekdays, with 6 AM being the most common. Closing times are usually between 7 PM and 10 PM, but 9:30 PM is pretty standard.

These longer hours are great if you need to fill up before or after work. Gas stations almost always open before the warehouse and close after.

But again, hours can shift depending on the area. If you want to be sure, look up your local Costco’s gas station hours online.

Weekend and Holiday Variations

On weekends, gas stations open later, usually around 7 AM, and close earlier, often by 8 PM or even 6 PM at some locations.

Weekend schedules are shorter since there’s less commuter traffic. Expect gas stations to open 1-2 hours later and close 1-2 hours earlier than during the week.

All Costco gas stations close on major holidays like:

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

No matter where you are in the U.S., if it’s a major holiday, the gas pumps are shut down. So, plan ahead if you need to fill up around those dates.

Factors That Can Affect Local Costco Hours

Costco’s hours aren’t set in stone everywhere. Where you live and what time of year it is can really make a difference.

Regional and State Variations

Costco tweaks its hours based on local demand and shopping habits. In big cities, stores might stay open longer than in small towns.

State laws sometimes force stores to close early on Sundays or certain holidays. And if there’s a lot of competition nearby, you might find your Costco open longer to keep up.

Weather can play a part too. Bad weather in some regions might mean shorter hours, while time zones can make for natural differences in opening and closing times.

Honestly, population matters. If you’re in a packed city, chances are your Costco is open longer than in a rural spot with fewer members.

Special Events and Seasonal Changes

Costco periodically adjusts its operating hours based on seasonal shopping patterns and special events.

During the holidays, you’ll usually find extended hours to handle all the extra shoppers.

Major holidays like Thanksgiving, Christmas, and New Year’s Day tend to bring reduced hours or even full closures at most locations.

Back-to-school season and the summer months? Those can mean temporary changes too, just to keep up with the rush.

Sometimes, local events shake things up. Community festivals, big sports games, or even wild weather might cause a store to tweak its schedule.

In the north, winter storms sometimes force stores to close early or open late. Store managers usually make the call, keeping an eye on safety and whatever the local authorities are saying.
