This national day is commonly known as the Fourth of July (or July Fourth or Independence Day). It commemorates the adoption of the Declaration of Independence on July 4, 1776, which was responsible for its independence from Great Britain. Independence Day is a huge celebration all over the country, including fireworks, concerts, parades, baseball games, barbecues, carnivals, fairs, picnics, political speeches, and various other public and private events.
4th of July celebrates the history, government, and traditions of the United States and is an opportunity for a reunion of family and friends as schools are closed, and the day is a holiday for almost everyone. All non-essential federal institutions are closed on Independence Day, too, as in 1938 the US Congress changed the day to be a paid federal holiday. The celebrations are also marked by patriotic displays: both decorations and clothing are colored white, red, and blue – like the colors of the American flag.
On July 2nd, 1776 the Continental Congress voted in favor of independence. On July 4th its 56 delegates finally adopted the Declaration of Independence and thirteen colonies (Connecticut, Delaware, Georgia, New Hampshire, New Jersey, New York, North Carolina, Maryland, Massachusetts Bay, Pennsylvania, Rhode Island and Providence Plantations, South Carolina, and Virginia) became the United States of America.
