The keyword phrase "patriots day april 21 2025" functions grammatically as a proper noun or, more specifically, a noun phrase. It operates as a single unit to name a specific, unique event: the holiday of Patriots' Day as it occurs on a particular date.
A breakdown of the phrase reveals its components. The core is "Patriots Day," which is a proper noun naming a holiday. The subsequent date, "April 21, 2025," acts as a modifier that specifies which instance of the holiday is being referenced.
