In 2025, Patriots' Day in Massachusetts will be observed on Monday, April 21. The central point of the keyword phrase "when is patriots day in massachusetts 2025" is the specific date, a temporal detail that functions as a noun. The holiday is statutorily defined as the third Monday in April.
Patriots' Day is a civic holiday commemorating the anniversary of the Battles of Lexington and Concord, the first military engagements of the American Revolutionary War, which occurred on April 19, 1775. Initially observed on the fixed date of April 19, Massachusetts state law was amended in 1969 to move the observance to the third Monday in April. This change was made to create a three-day weekend for workers and students, following the precedent of federal holidays.
The most significant practical application of this date is its association with the Boston Marathon, which is held annually on Patriots' Day. As a result, on April 21, 2025, state, county, and many municipal offices, along with public schools and some private businesses, will be closed in Massachusetts. The day is marked by historical reenactments, parades, and other commemorative events, particularly in the towns of Lexington and Concord.
