Patriots' Day is a state holiday, not a federal one. In 2025, it will be observed on Monday, April 21. It is officially recognized in Massachusetts, Maine, and Wisconsin. Its status as a holiday, with corresponding closures of state offices and public schools, is therefore limited to those specific states.
The observance is legally established on the third Monday in April to commemorate the anniversary of the Battles of Lexington and Concord, which were the first military engagements of the American Revolutionary War in 1775. As a state-level holiday, its impact on business operations is localized. While state government entities in the observing states close, federal agencies, such as the U.S. Postal Service, remain open. Many private businesses in the region may also close or operate on a reduced schedule, but there is no nationwide mandate to do so.
Consequently, for individuals residing or working in Massachusetts, Maine, or Wisconsin, April 21, 2025, will be a public holiday. For those in all other U.S. states and territories, it will be a regular Monday with no holiday-related closures. The practical application of its holiday status is entirely dependent on geographic location within the United States.
