Final answer:
Veterans Day should be capitalized because it is a proper noun referring to a specific holiday, following the same rules that apply to the capitalization of proper nouns like days, holidays, and historical periods.
Step-by-step explanation:
The word Veterans Day should always be capitalized since it is a proper noun referring to a specific holiday. According to standard English capitalization rules, proper nouns, which include days, holidays, and historical events, must be capitalized. Therefore, the correct way to write it is Veterans Day.
Additionally, it is important to recognize that, when mentioning events like the Spanish-American War, the names of wars and historical periods are also capitalized. Similarly, proper nouns such as Armistice Day and New York Journal are consistently capitalized to denote their significance. This follows the same capitalization rule that applies to words like Earth when they are used as the name of a planet.
