We celebrate American Independence Day on the Fourth of July every year. We think of July 4, 1776, as a day that represents the Declaration of Independence and the birth of the United States of America as an independent nation.
But July 4, 1776 wasn’t the day that the Continental Congress decided to declare independence (they did that on July 2, 1776).
It wasn’t the day we started the American Revolution either (that had happened back in April 1775).
Celebrations of the Fourth of July became more common as the years went on and in 1870, almost a hundred years after the Declaration was written, Congress first declared July 4 to be a national holiday as part of a bill to officially recognize several holidays, including Christmas. Further legislation about national holidays, including July 4, was passed in 1939 and 1941.
