One of the most important days in the American calendar is the adoption of the Declaration of Independence on 4th July, 1776.

This day marks the freedom of the nation from the rule of Great Britain and the emergence of a new sovereign country.

A national holiday, the 4th of July every year is celebrated by fireworks, parades, speeches by political leaders, carnivals and concerts. Fireworks are often accompanied by patriotic songs including the national anthem. Besides this, a salute of one gun for each state in the United States, called a salute to the union, is fired on Independence Day at noon by any capable military base.

This Independence Day marks the celebration of the nation's 236th birthday.
