Name two national U.S. holidays?

Labor Day and Thanksgiving are both recognized as national U.S. holidays established by federal law. Labor Day, celebrated on the first Monday in September, honors the contributions of American workers and the labor movement. Thanksgiving, celebrated on the fourth Thursday in November, is a time for families and friends to gather for a meal and give thanks for their blessings.

Other options include holidays that may be widely celebrated, but they do not have the same federal recognition. For example, Christmas and New Year's are broadly celebrated as well, but they do not both qualify as federally recognized holidays for the purposes of national observance in the same way that Labor Day and Thanksgiving do. Valentine's Day and Independence Day also do not fit as both a national day of observance under federal law, with Independence Day being the exception, while Halloween is generally seen more as a cultural celebration rather than an official holiday.
