Patriots Day in 2025 falls on Monday, April 21, 2025.

Quick scoop

  • Patriots’ Day is a state‑specific holiday observed mainly in Massachusetts and Maine to mark the first battles of the American Revolution on April 19, 1775.
  • In the modern federal calendar, it is celebrated on the third Monday of April , which places it on April 21 in 2025 rather than the historic April 19 date.

Why the date shifts

  • The holiday observance “floats” along with other American Monday‑shifted federal‑style dates.
  • In 2025 the third Monday lands on April 21 , but actual commemorations linked to the original April 19, 1775 events still center on that earlier date in reenactments and park programming.

What’s trending in 2025

  • The 2025 observance is especially notable as the 250th anniversary (“semiquincentennial”) of the battles of Lexington and Concord, driving extra reenactments, parades, and educational events around April 19–21.
  • From dawn salutes and “shot‑heard‑round‑the‑world” ceremonies to big Boston‑area parades and living‑history programs, many commemorations are spread across Saturday–Monday , even though the official holiday date is Monday, April 21.
