Is Costco Open Today? 2025 Holiday Hours & Best Times to Shop

Any Costco member who’s ever rolled up to a locked door on a holiday knows the feeling. The warehouse club runs on a tight, predictable schedule — open nearly every day, but closed on exactly seven major holidays each year. This guide lays out the full 2025 Costco hours playbook, from July 4 closures to the best weekday mornings to beat the crowds, all sourced from Costco’s official policies and verified editorial reports.

Number of Costco warehouses worldwide: over 800 ·
Standard weekday hours: 10:00 AM – 8:30 PM ·
Standard Saturday hours: 9:00 AM – 7:00 PM ·
Standard Sunday hours: 9:00 AM – 6:00 PM ·
Major holidays Costco closes each year: 7 ·
Slowest day of the week: Tuesday

Six key facts define Costco’s operating calendar and shopping patterns.

The pattern: Costco runs a narrow window on weekends — Sunday closes at 6 PM — and opens just 10 hours on weekdays. That consistency makes planning simple but unforgiving if you miss the window.

What Are the Holidays at Costco?

Which holidays does Costco close?

• Costco is closed on New Year’s Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day, according to Costco Customer Service (official policy).
• Holiday closures are consistent across all U.S. and Canadian warehouses, as confirmed by Costco Wholesale (official hours page).

Does Costco close for any half-days?

• Costco closes early on Christmas Eve and New Year’s Eve, with reduced hours typically running 9:00 AM – 5:00 PM, per GOBankingRates (personal finance site).
• Exact half-day schedules may vary by location and year; the official Costco warehouse locator is the definitive source.

The implication: For a member planning a shopping run near a major holiday, the window shrinks — but the pattern is so predictable that you can plan months ahead.

Is Costco Open on July 4?

What are Costco’s July 4 hours?

• Costco is closed on July 4th, as stated by Costco Customer Service (official policy).
• Stores reopen on July 5th with normal hours, typically 10:00 AM – 8:30 PM on a weekday, confirmed by DealNews (retail hours tracker).

Are Costco stores open on July 4th?

• No. California stores are also closed on July 4, per official announcement from Costco Wholesale (official hours page).
• Independence Day is one of the seven guaranteed closure days nationwide, with no exceptions for state holidays.

Why this matters: July 4 is a peak grilling and picnic day — if you need propane, buns, or burgers, the day before is your only option.

Is Costco on Christmas Eve?

What time does Costco close on Christmas Eve?

• Costco is open on Christmas Eve with reduced hours, typically 9:00 AM – 5:00 PM, according to GOBankingRates (personal finance site).
• Christmas Eve hours may vary by location, so the Costco warehouse locator is the recommended check.

Is Costco open on Christmas Day?

• Costco is closed on Christmas Day, as confirmed by Costco Customer Service (official policy).
• Christmas is one of the seven guaranteed closure days; no warehouse operates on December 25.

The trade-off: You get a 7-hour window on Christmas Eve afternoon — expect lines to be longer, but at least you can grab last-minute ingredients.

What holidays is Costco closed near me?

How to find local Costco holiday hours?

• Use the Costco warehouse locator (official tool) on costco.com, entering your zip code or city for store-specific holiday hours.
• Business centers and fuel stations may have different hours; the locator shows those separately.

Are Costco hours the same in Canada?

• Costco Canada follows the same major holiday closures, but regional holidays like Family Day, Victoria Day, and Quebec National Holiday affect hours, per Costco Business Centre Canada (regional policy).
• Costco Canada Liquor stores have separate schedules — closed on Family Day, Easter Sunday, Victoria Day, Canada Day, Labour Day, Thanksgiving, Christmas, and New Year’s Day, with reduced hours on Christmas Eve and Boxing Day, as listed by Costco Canada Liquor (official liquor hours).
• Local variations apply: Quebec is open on some holidays when other provinces are closed, according to Costco Business Centre Canada (regional policy).

The pattern: If you’re in Canada, check both the warehouse locator and the separate business centre page — the same holiday can mean open in Quebec but closed in Ontario.

When Not to Go to Costco?

What is the slowest day at Costco?

• Weekday mornings (opening to 11 AM) are least crowded, with Tuesday consistently reported as the slowest day, per DealNews (retail hours tracker).
• Wednesday is the second slowest day, based on crowd pattern analysis from GOBankingRates (personal finance site).

What are the best and worst times to shop?

• Weekends are busiest, especially Saturday afternoons from 1 PM to 4 PM, as documented by DealNews (retail hours tracker).
• Avoid after-work hours on weekdays (5 PM – 7 PM), when employees and families flood the aisles.
• The slowest day is typically Tuesday, with Wednesday a close second.

The catch: If you can only shop on weekends, go right at opening on Saturday or Sunday — the first hour is the quietest, even on the busiest days.

Costco Hours 2025: What Members Need to Know

For a 2025 Costco member, the hours game is simple but unforgiving: open 7 days a week, but on those 7 holidays, the warehouse is locked. The predictable schedule means you can plan your shopping around the crowds — Tuesday morning is the golden window, and the holiday closures are fixed. The trade-off is that you lose flexibility on weekends (Sunday closes at 6 PM) and during the holiday rush, but you gain reliability.

The implication for a member planning around holidays: if you need a bulk run near July 4 or Christmas, you have a narrow window. For Canadian customers, the complexity multiplies — province-specific holiday rules for business centres and liquor stores demand extra attention. The bottom line: Costco’s hours are remarkably consistent, but that consistency means you either show up during the open window or you wait.
