Which two holidays are recognized as national holidays in the United States?

Thanksgiving and Independence Day are recognized as national holidays in the United States and hold significant cultural and historical importance. Independence Day, celebrated on July 4th, commemorates the adoption of the Declaration of Independence in 1776, marking the birth of the nation. It is celebrated with fireworks, parades, and various festivities that honor American independence.

Thanksgiving, celebrated on the fourth Thursday of November, originated as a harvest festival and is a time for families to come together, reflect on their blessings, and enjoy a traditional meal, often centered around turkey. This holiday emphasizes gratitude and the celebration of bonds within families and communities.

In contrast, other options provided do not encompass both elements of being recognized national holidays. Christmas, while widely celebrated, is not a federal national holiday in the same sense as Thanksgiving and Independence Day. Halloween, although popular, does not qualify as a national holiday. Similarly, New Year's Day is recognized as a federal holiday, but Flag Day and New Year's Day are not designated as national holidays in the same manner as the two selected. Labor Day and Memorial Day are indeed national holidays, but they are distinct from the chosen answer, which specifically highlights the cultural and historical significance of Thanksgiving and Independence Day.
