The keyword phrase "what holiday is after patriot day" functions as a noun clause. The core of the query is the noun "holiday," seeking the identification of a specific event. The next federal holiday in the United States after Patriot Day (September 11) is Columbus Day, which is observed on the second Monday in October. In many states and localities, this day is officially celebrated as Indigenous Peoples' Day.
Patriot Day is a National Day of Service and Remembrance observed annually on the fixed date of September 11. It is a national observance but not a federal holiday, meaning most businesses and government offices remain open. In contrast, Columbus Day is one of the official U.S. federal holidays. This distinction is important, as several other cultural or commemorative days, such as Halloween (October 31), occur between Patriot Day and the next federal holiday, but they do not carry federal recognition or provide for a day off from work.
Therefore, when identifying the subsequent holiday, the most precise answer depends on the classification of "holiday." For the purposes of the official U.S. calendar and federal work schedules, the correct response is Columbus Day / Indigenous Peoples' Day. If the term is used more broadly to include any major cultural celebration, then Halloween would also be a valid answer that falls within the same timeframe.
