Patriots' Day is an official state holiday in Massachusetts, observed annually on the third Monday in April. The legal holiday commemorates the anniversary of the Battles of Lexington and Concord, which were the first military engagements of the American Revolutionary War on April 19, 1775. Maine and Wisconsin also officially observe the day, though it is most famously associated with Massachusetts.
As a result of its status as a public holiday, non-essential state, county, and municipal government offices are closed. Public schools, colleges, and universities also close for the day. While many private sector businesses close in observance, it is not mandatory, and many retail and service establishments remain open. It is not a federal holiday, so federal institutions such as the United States Postal Service maintain normal operations. The day is marked by significant cultural events, including historical reenactments in Lexington and Concord and the running of the Boston Marathon.
Therefore, for individuals within Massachusetts, the day functions as a public holiday with widespread closures of government and educational institutions. The observance by private businesses is variable, so it is advisable to confirm the operating status of specific companies. The holiday's distinct regional character makes it a significant day of historical remembrance and civic celebration within the state, separate from the national holiday calendar.
