Evacuation Day in Massachusetts takes place on March 17, 2025. It is observed in Suffolk County and also by the public schools in Cambridge and Somerville, Massachusetts. The holiday commemorates the evacuation of British forces from the city of Boston following the Siege of Boston, early in the American Revolutionary War. Schools and government offices are closed. If March 17 falls on a weekend, schools and government offices are closed on the following Monday in observance. It is the same day as Saint Patrick's Day, a coincidence that played a role in the establishment of the holiday. (With material from: Wikipedia)
