Is Costco open on Columbus Day? All the stores open and closed on Oct. 12

Key Points:

• Columbus Day 2026 is observed on Monday, October 12, as a federal holiday in most U.S. states except Hawaii, which celebrates Discoverers’ Day instead; Indigenous Peoples’ Day is also recognized nationally alongside Columbus Day since 2021.
• U.S. Postal Service offices will be closed and no mail delivery will occur on Columbus Day, though private carriers like FedEx, Amazon, and UPS will operate on regular or modified schedules.
• Most banks will be closed except for TD Bank and Chase, which will remain open with limited services; grocery stores and retail outlets are generally open, often with regular hours, but some may vary by location.
• Restaurants and liquor stores are expected to operate normally for dine-in, takeout, and delivery, while the New York Stock Exchange and Nasdaq will be open, though bond markets will be closed.
• The next federal holidays after Columbus Day are Veterans Day on November 11, Thanksgiving on November 26, and Christmas on December 25.
