For anybody who has any connection whatsoever to the United States, today is Independence Day, commonly referred to as the "Fourth of July". It is a federal holiday that commemorates the adoption of the Declaration of Independence on July 4, 1776, declaring independence from Great Britain.
In the States (and anywhere ex-pat Americans gather in any number) 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.
So from the Christmas Miscellany blog and me the author, Jonathan Green, Happy Fourth of July!
