The keyword phrase functions as an interrogative clause, combining proper nouns that refer to separate, though historically related, observances. The core concepts are "Veterans Day" and "Poppy Day" (more formally known as Remembrance Day). The term does not refer to a single, officially recognized holiday but rather conflates two distinct commemorations: Veterans Day in the United States and Remembrance Day in Commonwealth nations, both of which occur on November 11.
Both holidays originate from Armistice Day, which was established to mark the end of World War I on November 11, 1918. In the United States, the holiday was officially renamed Veterans Day in 1954 to honor all military veterans, both living and dead. In contrast, Commonwealth countries such as the United Kingdom, Canada, and Australia retained the focus on commemorating armed forces members who died in the line of duty, observing the date as Remembrance Day. The red remembrance poppy became the central symbol of this day, inspired by the poem "In Flanders Fields," making it colloquially known as "Poppy Day." While poppies are used for remembrance in the U.S., they are more strongly associated with Memorial Day (the last Monday in May) and the designated National Poppy Day (the Friday before Memorial Day).
In summary, the date of observance depends on the specific holiday in question. Veterans Day in the U.S. is November 11 and honors all who have served. Remembrance Day (or "Poppy Day") in Commonwealth nations is also November 11 but specifically honors the war dead, with the poppy as its iconic symbol. Therefore, a "Veterans Poppy Day" does not formally exist; the query merges the name of a U.S. holiday with the primary symbol of a Commonwealth holiday that share the same date.
