This article provides a detailed overview of whether Costco, UPS, the stock market, and the post office are open today, offering insights into their schedules and holiday policies.
Costco is generally open on most days, but it's essential to check for any holiday closures or special hours. On January 20, 2026, Costco is open. However, hours may vary by location, so it's recommended to use the Costco Store Locator to confirm the specific hours of your local warehouse.

Martin Luther King Jr. Day, celebrated on the third Monday of January, is a federal holiday in the United States. However, UPS observes different operational schedules for holidays. On January 20, 2026, UPS will be closed in observance of MLK Day. Similarly, the USPS (United States Postal Service) will be closed, meaning there will be no mail delivery today. This closure affects both package delivery and regular mail services, so if you have any urgent shipments, plan accordingly to avoid delays.
For investors and traders, it's important to note that the stock market is closed today in observance of Martin Luther King Jr. Day. Both the New York Stock Exchange (NYSE) and Nasdaq will be closed, which means no trading activities will occur. This closure aligns with the federal holiday schedule, and normal trading will resume on the following business day, which is January 21, 2026.
Understanding the operational status of essential services on federal holidays like Martin Luther King Jr. Day is key to planning your activities and avoiding inconveniences. While Costco remains open on January 20, 2026, other services such as UPS, the post office, and the stock market will be closed. Always double-check with the specific service provider for the most accurate and up-to-date information. Whether you're a shopper, investor, or sender of packages, being prepared for these closures ensures a smoother experience.
