Patriots' Day is not a federal holiday in the United States. It is an official statutory holiday exclusively in the states of Massachusetts and Maine. It is also observed as a public school holiday in Wisconsin.
Observed annually on the third Monday in April, the holiday commemorates the Battles of Lexington and Concord, which marked the start of the American Revolutionary War on April 19, 1775. In the jurisdictions where it is a statutory holiday, state and local government offices, public schools, libraries, and many private businesses are closed. The day is known for civic ceremonies, historical reenactments, and hosting the Boston Marathon in Massachusetts.
The key distinction is its regional legal status. Unlike federal holidays that apply nationwide, the observance of Patriots' Day is limited to the specific states that have legislated it as such. Therefore, for the majority of the U.S. population and workforce, it is a standard business day.
