In 2026, Patriots' Day will be observed on Monday, April 20. The keyword phrase "what day is patriots day in 2026" functions as a noun phrase, where the core subject is the date of the holiday. The answer to this query is a specific date, which is determined by a set rule rather than a fixed calendar day.
The date of Patriots' Day is legally defined as the third Monday in April. This observance is a state holiday in Massachusetts and Maine, and a public school holiday in Wisconsin. It commemorates the anniversary of the Battles of Lexington and Concord, the first military engagements of the American Revolutionary War, which occurred on April 19, 1775. The shift from the fixed date of April 19 to the third Monday was enacted to create a three-day weekend.
As a result of this scheduling, the date changes annually. For the year 2026, the first Monday of April is April 6, the second is April 13, and the third is therefore April 20. This specific date is significant as it dictates the timing for various regional events, most notably the running of the Boston Marathon, which is traditionally held on Patriots' Day.
