In the United States, Independence Day, commonly known as the Fourth of July, is a federal holiday commemorating the adoption of the Declaration of Independence on July 4, 1776, declaring independence from the Kingdom of Great Britain. Independence Day is commonly associated with fireworks, parades, barbecues, carnivals, fairs, picnics, concerts, baseball games, political speeches and ceremonies, and various other public and private events celebrating the history, government, and traditions of the United States. Independence Day is the national day of the United States
One of the most enduring myths about Independence Day is that Congress signed the Declaration of Independence on July 4, 1776. The myth had become so firmly established that, decades after the event and nearing the end of their lives, even the elderly Thomas Jefferson and John Adams had come to believe that they and the other delegates had signed the Declaration on the fourth. Most delegates actually signed the Declaration on August 2, 1776. In a remarkable series of coincidences, both John Adams and Thomas Jefferson, two founding fathers of the United States and the only two men who signed the Declaration of Independence to become president, died on the same day: July 4, 1826, which was the United States' 50th anniversary.
Independence Day is a national holiday marked by patriotic displays. Similar to other summer-themed events, Independence Day celebrations often take place outdoors. Independence Day is a federal holiday, so all non-essential federal institutions (like the postal service and federal courts) are closed on that day. Many politicians make it a point on this day to appear at a public event to praise the nation's heritage, laws, history, society, and people.
Families often celebrate Independence Day by hosting or attending a picnic or barbecue and take advantage of the day off and, in some years, long weekend to gather with relatives. Decorations (e.g., streamers, balloons, and clothing) are generally colored red, white, and blue, the colors of the American flag. Parades often are in the morning, while fireworks displays occur in the evening at such places as parks, fairgrounds, or town squares.
Independence Day fireworks are often accompanied by patriotic songs such as the national anthem "The Star-Spangled Banner", "God Bless America", "America the Beautiful", "My Country, 'Tis of Thee", "This Land Is Your Land", "Stars and Stripes Forever", and, regionally, "Yankee Doodle" in northeastern states and "Dixie" in southern states. Some of the lyrics recall images of the Revolutionary War or the War of 1812. While the official observance always falls on July 4th, participation levels may vary according to which day of the week the 4th falls on. If the holiday falls in the middle of the week, some fireworks displays and celebrations may take place during the weekend for convenience, again, varying by region.(From: Wikipedia, license: CCA-SA)
