Well actually, yes and no on that countrigal. It's always known as the "fourth" regardless of what day businesses are closed.
However, when it falls on a Tuesday or Thursday, it's not uncommon for companies to move the actual day off to the Monday or Friday.

But generally speaking, yes, it's always the Fourth of July.
Funny, last night hubby and I were reading the history of the Yankee Doodle Dandy song, which started as a mocking song sung by the British during Revolutionary War days, making fun of the Americans as essentially being redneck fools who thought sticking a feather in their cap made them fashionable. The Americans embraced it as their own following some of the battles. Quite a humorous background for reading actually.
