My 2026 Labor Day Costco Check: September 7 Is a Closure Day
Costco’s official policy lists Labor Day as a closure day for U.S. warehouses, and Labor Day falls on Monday, September 7, in 2026.
Why I looked this up
I wanted to know whether a Costco trip would be possible on Labor Day, so I checked Costco’s own U.S. holiday policy instead of relying on search-result summaries.
The short answer is no: Costco says its U.S. warehouses are closed on Labor Day.
For 2026, the date matters too. The U.S. Office of Personnel Management’s federal holiday schedule identifies Labor Day as Monday, September 7, 2026.
Key takeaway
Here is the decision in one line:
| Question | What the official sources say |
|---|---|
| Is Costco open on Labor Day? | Costco’s holiday-closure policy says U.S. warehouses are closed. |
| When is Labor Day in 2026? | Monday, September 7, 2026. |
| Should I expect reduced warehouse hours instead? | No warehouse opening hours are given for the holiday because Costco lists it as a closure day. |
That conclusion is specifically about U.S. Costco warehouses. I would not extend it to every Costco operation or use it as a schedule for locations outside the United States.
My check-before-going list
This is the order I would use when planning around the holiday:
- Check the date. In 2026, Labor Day is Monday, September 7.
- Check the national closure policy. Costco includes Labor Day among the holidays when its U.S. warehouses are closed.
- Check the local listing for another day. Costco’s warehouse locator lets me search by city, state, or ZIP code and select a warehouse to view its hours and upcoming holiday closures.
The practical result is that I would move an in-person warehouse visit to a different day rather than plan around special Labor Day hours.
What I looked up next
I also wanted to know how I could verify the schedule for a particular warehouse before visiting on a nearby date. Costco directs shoppers to select their local warehouse in its locator, where the location’s hours and upcoming holiday closures are displayed.
That local check is useful for planning the days around Labor Day, but it does not change Costco’s stated U.S. warehouse closure for Labor Day itself.
