Massachusetts State Holidays 2027

Last reviewed: May 19, 2026 · Holiday data: June 23, 2026

Massachusetts state government offices observe 12 holidays in 2027: the federal holidays plus 1 state-specific day (Patriots' Day). Banks and most private employers in the United States follow the federal calendar, so a standard business-day count is unchanged: 2027 has 250 federal working days.

How Massachusetts's holidays differ from the federal set

Massachusetts adds Patriots' Day, observed on the third Monday of April, marking the 1775 battles of Lexington and Concord and the running of the Boston Marathon. It is a statewide holiday for Massachusetts government offices under the General Laws. Suffolk County, which includes Boston, also observes Evacuation Day (17 March) and Bunker Hill Day (17 June), but those are county holidays rather than statewide ones. Banks and most private employers follow the federal calendar, so the working-day total uses the federal holidays and is not changed by Patriots' Day.

Effect on business-day counts

The working-day total on this page uses the federal holidays that banks and the Federal Reserve observe nationwide. The Massachusetts holidays listed here are state-government office closures; most private employers do not close for them, so they usually do not change a business-day count. Observed dates can shift when a state holiday falls on a weekend.
