Which date marked Boston’s 250th Evacuation Day celebration during America250?
Answer
March 17, 2026
Boston’s 250th Evacuation Day celebration was scheduled for March 17, 2026.
Evacuation Day commemorates the British evacuation of Boston on March 17, 1776, after the Siege of Boston. The withdrawal followed the American fortification of Dorchester Heights, which forced British forces and their loyalist supporters to leave the city. The date later became associated with Boston’s St. Patrick’s Day celebrations.
The 2026 observance formed part of the city’s America250 programming. The National Park Service planned a major overhaul of the Dorchester Heights Monument in connection with the 250th anniversary, highlighting the military episode that ended British occupation of Boston.
Evacuation Day is not the same event as Independence Day. It marks a Revolutionary War military development in March 1776, several months before the Declaration of Independence was adopted on July 4. Boston’s celebration therefore commemorated a 250th anniversary within the broader 2026 program.
