Which of the following is another recognized national U.S. holiday?

New Year's Day is recognized as a national holiday in the United States. It is celebrated on January 1st and marks the beginning of the new calendar year. This holiday is observed with various traditions and festivities, including parties, fireworks, and resolutions for the upcoming year.

In contrast, Valentine's Day, while celebrated widely, is not designated as a national holiday; it is a cultural celebration that occurs on February 14th, focusing on love and romance. Halloween, celebrated on October 31st, is also not a national holiday and is known for costumes and trick-or-treating. Thanksgiving, although widely celebrated and an important cultural event in the U.S., is recognized as a holiday that occurs on the fourth Thursday of November, but the question specifically seeks a national holiday that is widely acknowledged across the country. New Year's Day meets that criteria.
