Patriots’ Day - third Monday in April, the Battles of Lexington and Concord, and the Boston Marathon

Patriots\u2019 Day is one of the most eventful civic days on the American calendar. It commemorates the first military engagements of the Revolutionary War, re-enacts them twice on the same day, and hosts the world\u2019s most-watched 26.2-mile footrace in the middle of them.

The April 19 battles in detail

The engagement also produced the first American casualty of the war: the colonists at the Green in Lexington included Robert Munroe, the first man killed, plus Jonas Parker, Samuel Hadley, Jonathan Harrington, and four others whose names are recorded on the Lexington Battle Green monument. Captain John Parker, the militia captain, had been suffering from tuberculosis and died of the illness in September 1775, months after the battle. The British retreat to Boston, under constant colonial fire along the roughly 16-mile route, is sometimes credited as the day the colonies became, in effect, a single revolutionary force.

The battles of Lexington and Concord are the most- studied single-day engagements in early American military history. The minuteman response at the Old North Bridge in Concord is widely regarded as the first organised colonial militia resistance to British troops in the war, though several earlier skirmishes (including the Powder Alarm of September 1774 and the Gunpowder Incident of March 1775) prefigured it. The British expedition from Boston was led by Lieutenant Colonel Francis Smith, with Major John Pitcairn leading the advance guard at Lexington. Paul Revere's ride (actually coordinated by Revere, William Dawes, and Samuel Prescott) alerted the colonial militia that evening.

The first shots of the American Revolutionary War were fired at Lexington at approximately 7:30 a.m. on April 19, 1775, when roughly 77 colonial Minutemen faced about 700 British regulars. Eight Minutemen were killed and ten wounded; British losses were one wounded. The skirmish at Lexington Green lasted roughly 15 minutes before the Minutemen dispersed. The British column then marched to Concord, where colonial militia engaged them at the Old North Bridge around 9 a.m. The Concord fight killed two colonists and three British soldiers. By the end of the day, British casualties were 273 (73 killed, 174 wounded, 26 missing) versus 93 American (49 killed, 39 wounded, 5 missing). The battles are sometimes collectively called the "shot heard 'round the world," a phrase coined by Ralph Waldo Emerson in his 1837 Concord Hymn.

Other states that observe Patriots' Day

Wisconsin has observed the third Monday of April as a public-school observance day since 1928. Maine and Connecticut observe by proclamation; the District of Columbia lists Patriots' Day on its ceremonial calendar. Several other states (Florida, Iowa, Kentucky) have proposed legislation to recognise the day but none has passed. The patchwork of state observances means Patriots' Day remains the least uniformly observed of the major civic-memory days in the US.

Some states have proposed moving the observance from the third Monday of April to the actual April 19 anniversary; the proposals have not advanced. The current pattern (third Monday) was established by the Uniform Monday Holiday Act of 1971, which consolidated several federal holidays to Mondays but did not affect Patriots' Day (which was already a Monday). Patriots' Day is not a federal holiday; federal employees do not receive a day off.

Origins

The Commonwealth of Massachusetts established Patriots\u2019 Day in 1894 under Governor Frederic T. Greenhalge as a public holiday on April 19, the anniversary of the 1775 battles. The legislature moved it to the third Monday in April in 1969 to create a three-day weekend (the same Uniform Monday Holiday Act logic applied to Memorial Day and Columbus Day at the federal level). Maine, Wisconsin, and Connecticut adopt it through either statute or executive order with variations; the Commonwealth of Virginia observes it as a public-school "Patriots\u2019 Day" in April.

Lexington and Concord, April 19, 1775

Paul Revere, William Dawes, and Samuel Prescott completed the midnight ride that warned Middlesex County. Captain John Parker\u2019s militia lined up on Lexington Green and dispersed. Then a single shot - no one knows from which side - touched off a volley that killed 8 colonists and wounded 10. The British regulars marched 6 more miles to Concord, where they faced stiffer resistance at the North Bridge; the retreat back to Boston became a running fight through every town in between. By nightfall 73 British soldiers were dead, 174 wounded or missing; 49 colonists had been killed.

The Boston Marathon (since 1897)

The Boston Athletic Association founded the marathon in 1897, inspired by the 1896 Olympic marathon. The race has run on Patriots\u2019 Day every year since, except 2020 (COVID-19, held virtually in September) and 2013 (cancelled after the April 15 bombings; the field returned to the course in 2014). Start time is 9:02 a.m. Eastern in Hopkinton; finish on Boylston Street; current course record is 2:03:02 by Geoffrey Mutai (2011). The 2026 field runs April 20.

Reenactments

The Lexington Minute Men and the Concord Independent Battery stage dawn reenactments at their respective greens. Around 5:30 a.m., approximately 150 reenactors in colonial militia dress line up on Lexington Battle Green; at 6 a.m., the British column marches in. The North Bridge reenactment in Concord begins around 9 a.m. Both events are free.

Where the date is contested

The third-Monday rule means the day rarely falls on the actual April 19 anniversary: in 2027 the calendar happens to align, but in 2026 it is one day later. Critics argue the holiday loses pedagogical value when the events it commemorates happened on a different date; defenders prefer the three-day weekend for parade and marathon logistics.

Modern observance

Patriots' Day observance has been most thoroughly commercialised in Massachusetts, where the Boston Marathon has been run since 1897 (always on Patriots' Day, with an exception in 2020 and 2021 during the pandemic). The marathon draws 30,000+ runners and roughly 500,000 spectators, making it one of the largest single-day sporting events in the United States. The Red Sox have played a morning home game on Patriots' Day since 1959, the earliest first pitch in Major League Baseball.

Re-enactments of the April 19, 1775 battles run at the Lexington Battle Green and the Old North Bridge in Concord, with participants in period costume and a synchronised line-of-fire across both towns. The Minute Man National Historical Park administers the re-enactments under the National Park Service. Smaller observances take place at the Hancock-Clarke House in Lexington and at the Munroe Tavern.
