Why the Fourth of July Date was Chosen?

Though the Fourth of July is almost iconic to Americans, some claim the date itself is somewhat arbitrary. New Englanders had been fighting Britain since April 1775. The first motion in the Continental Congress for independence was made on June 8. After hard debate, the Congress voted unanimously (12-0), but secretly, for independence from the Kingdom of Great Britain on July 2 (see Lee Resolution).

The Congress reworked the text of the Declaration until a little after eleven o'clock, July 4th, when thirteen colonies voted for adoption and released an unsigned copy to the printers. (New York abstained from both votes.) Philadelphia celebrated the Declaration with public readings and bonfires on July 8. Not until August 2 would a fair printing be signed by the members of the Congress, but even that was kept secret to protect the members from British reprisal.

John Adams, credited by Thomas Jefferson as the unofficial, tireless whip of the independence-minded, wrote his wife Abigail on July 3:

The second day of July, 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations, from one end of this continent to the other, from this time forward forever more.

Adams was off by two days, however. Certainly, the vote on July 2 was the decisive act. But July 4 is the date on the Declaration itself. Jefferson's stirring prose, as edited by the Congress, was first adopted by the vote of the 4th. It was also the first day Philadelphians heard the official news of independence from the Continental Congress, as opposed to rumors in the street about secret votes.
