No, Patriots' Day is not a holiday for the United States Postal Service (USPS). Post offices remain open, and regular mail delivery and collection services operate on their normal schedules. The USPS observes federal holidays, whereas Patriots' Day is a state-level observance.
The distinction lies in governmental jurisdiction. Federal holidays are designated by the U.S. Congress and are observed by all federal government agencies, including the USPS, nationwide. In contrast, state holidays are established by individual state legislatures. Patriots' Day is an official civic holiday recognized only in Massachusetts and Maine, commemorating the anniversary of the Battles of Lexington and Concord. While state and local government offices, schools, and some businesses in these states close, federal entities are not affected.
Consequently, for postal customers, all operations are standard. Individuals can expect mail to be delivered and can conduct business at post office locations on Patriots' Day, even within Massachusetts and Maine. The operational status of the USPS on any given day is determined solely by the federal holiday calendar, not by state or local observances.
