Patriot Day in Massachusetts in 2025 will be observed on Monday, April 21st.
This date is established by state law, which designates Patriot Day as occurring on the third Monday of April annually. The holiday commemorates the Battles of Lexington and Concord, the initial military engagements of the American Revolutionary War, which took place on April 19, 1775. While the original historical events happened on a specific date, the modern observance shifts to the nearest Monday to create a three-day weekend for the state holiday.
As a state-specific observance, Patriot Day in Massachusetts is distinct from the federal Patriot Day observed on September 11th. The Massachusetts holiday remains a significant cultural and historical marker, traditionally coinciding with the running of the Boston Marathon, which further integrates the commemorative event into the public consciousness and annual calendar of the Commonwealth.
