The keyword phrase "when is patriots day this year 2025" functions as a noun clause seeking a specific date. The main point and answer is the date itself, which is a noun. In 2025, Patriots' Day will be observed on Monday, April 21.
This holiday is a state-level observance in Massachusetts and Maine, commemorating the anniversary of the Battles of Lexington and Concord on April 19, 1775. The date of observance is not fixed to April 19 but is legally mandated to occur on the third Monday in April. This floating holiday structure ensures it always creates a three-day weekend.
A significant practical application of this scheduling is the running of the Boston Marathon. The event is traditionally held on Patriots' Day to coincide with the holiday in Massachusetts. Consequently, the 129th Boston Marathon is scheduled for April 21, 2025.
