Over three days in Philadelphia (July 2, 3 and 4, 1776) the Continental Congress set the path for what would become the United States of America:
 

July 2, 1776
The Continental Congress votes to declare independence from Great Britain, formally adopting the Lee Resolution. The next day John Adams writes in a letter to his wife that, "The second day of July, 1776, will be the most memorable epocha in the history of America. . . . 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, forevermore."

July 3, 1776
The Continental Congress begins debating and editing the draft Declaration, eventually making 86 edits and cutting the length by about a fourth.

July 4, 1776
The Continental Congress approves the final draft of the Declaration, formalizing what had already been decided on July 2. Congress hires printer John Dunlap to print copies of the Declaration to be distributed throughout the colonies.

As you fulfill John Adam's solemnization with pomp, guns, bonfires and sports - Have a safe and happy Independence Day and weekend
