Patriot's Day is a state holiday observed in Massachusetts on the third Monday in April. It is therefore celebrated on this day in Boston.
The holiday officially commemorates the anniversary of the Battles of Lexington and Concord, which took place on April 19, 1775, and marked the beginning of the American Revolutionary War. While historically observed on April 19, the date was formally changed in Massachusetts in 1969 to be celebrated on the third Monday of April, creating a three-day weekend.
In Boston, the day is synonymous with the Boston Marathon. The world-renowned race has been held on Patriot's Day every year since 1897, making the holiday a significant date for both its historical commemoration and this major international sporting event.
