In 1964, the name of the July 4 holiday was changed to Republic Day. In Rwanda, July 4 is an official holiday known as Liberation Day, commemorating the end of the 1994 Rwandan Genocide in which the U.S. government also played a role. Denmark also celebrates American independence on July 4.he 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.
