The U.S. celebrates July 4, but independence from Britain is marked around the globe. Here's a look at how and when different countries celebrate.

On July 4, the United States celebrates its independence from Britain with displays of fireworks, barbeques, shopping — and for an estimated 70 million citizens this year, travel. 

The United States' celebration is held on the anniversary of the Second Continental Congress' adoption of the Declaration of Independence in 1776. But America isn't the only country that celebrates independence from Britain. Much of the global population —  around one-fifth of the world, according to Guinness World Records — were subjects of Great Britain prior to 1914. 

Some countries don't celebrate their independence from the United Kingdom, but instead dedicate a day to celebrating their formation. Others celebrate similarly to the United States, on the day the country either declared or formally gained independence from the United Kingdom.
