The United States observes Independence Day as a federal holiday to remember the adoption of the Declaration of Independence by the Second Continental Congress on July 4, 1776.
The Thirteen Colonies were declared to be a single, free, and independent state by the Second Continental Congress, and no longer subject and subordinate to King George III of Great Britain.
On July 2, the Congress approved independence, and on July 4, two days later, it adopted the Declaration of Independence.
American Independence History and Date

The legal separation of the thirteen colonies from Great Britain during the American Revolution took place on July 2, 1776, when the Second Continental Congress voted to endorse a resolution of independence that Virginia’s Richard Henry Lee had proposed in June and proclaimed the United States independent from Great Britain’s rule.
After voting in favour of independence, Congress focused on the Declaration of Independence, a document that served as an explanation for the choice. It was written by a Committee of Five, with Thomas Jefferson serving as the document’s primary author.
Congress debated and changed the Declaration’s language to eliminate its strident condemnation of the slave trade before finally passing it on July 4 two days later. John Adams had written his wife a letter the day before.
Adams’ prediction was two days late. Instead of July 2, when the resolution of independence was approved in a closed session of Congress, Americans began to celebrate independence on July 4, the date listed on the widely publicised Declaration of Independence.
Since then, the United Nations of America has annually observed July 4 as Independence Day
How America Celebrates its Independence Day?

Other countries that celebrate July 4

Ireland: It comes as no surprise that Ireland hosts its own Fourth of July Irish-America Fest given its close ties to the US.
The festival, which takes place every year in New Ross, lasts five whole days and is jam-packed with activities, cuisine, and music with American influences.
The Declaration of Independence is read aloud to begin the event, which is then followed by the ceremonial hoisting of the flag.
Sydney, Australia: It should come as no surprise that July 4th celebrations travel all the way to Australia, with Sydney hosting the biggest event in the Southern Hemisphere!
The parties, which are sponsored by Sydney Americans and include American DJs and, of course, American food and drink, are held along the city’s famous harbour.
