About Bunker Hill Day

Bunker Hill Day is associated with 17 June in Suffolk County, Massachusetts, and commemorates the Battle of Bunker Hill fought on 17 June 1775.

Massachusetts law includes Bunker Hill Day as a legal holiday with respect to Suffolk County only, while also requiring state and municipal offices there to remain open and appropriately staffed.

Why Bunker Hill Day matters

The day marks a major early battle of the American Revolution and remains closely associated with Charlestown and the Bunker Hill Monument.

Its legal status is narrower than a statewide office-closure holiday, so the statutory wording matters when describing the day.

History of Bunker Hill Day

The Battle of Bunker Hill was fought on 17 June 1775 in Charlestown, with much of the fighting occurring on Breed’s Hill.

The National Park Service describes the battle as the first major pitched battle between New England forces and the British army during the Revolution.

Massachusetts General Laws currently include Bunker Hill Day on June 17 as a Suffolk County legal holiday.

The same statute specifies that state and municipal agencies and other public offices in Suffolk County remain open and appropriately staffed on the day.
