What will stay open or close in the United States on Labor Day?

Labor Day will close government offices, schools, courts, post offices, banks and U.S. stock markets, but most major retailers and grocery stores will keep their doors open. Many will offer promotional sales, while Costco warehouses will close for the holiday.

The holiday traces its origins to labor activism in the late 19th century. New York held the first Labor Day celebration on Sept. 5, 1882, when about 10,000 workers marched in a parade organized by the Central Labor Union and the Knights of Labor. President Grover Cleveland signed the law establishing the first Monday in September as a legal holiday in 1894.

Standard FedEx and UPS pickup and delivery services will not operate, although some critical services will remain available at certain locations. Store hours may differ, so shoppers are advised to check locally.

Millions of Americans are expected to take to the roads or fly during the last major travel weekend of summer. AAA says airfares to major domestic destinations are nearly 20% higher than last year, hotel rates have also risen, and regular gasoline averages just under $4.10 a gallon, up 90 cents from the same period last year. Cruises departing from U.S. ports are about 4% cheaper. AAA recommends checking the weather and inspecting a vehicle’s tires, battery and fluid levels before a road trip.
