In the USA, Independence Day is on the 4th of July, yes there was a movie with this same title and no I am not going to post that movie here even though I did like it. That is the day we commemorate the signing of the Declaration of Independence. We typically have great celebrations all across America in the form of BBQ's, Family Picnics, Parades, Concerts and of course Fireworks.
For those needing a history lesson, this is from Wikipedia:
During the American Revolution, the legal separation of the American colonies from Great Britain occurred on July 2, 1776, when the Second Continental Congress voted to approve a resolution of independence that had been proposed in June by Richard Henry Lee of Virginia. After voting for independence, Congress turned its attention to the Declaration of Independence, a statement explaining this decision, which had been prepared by a Committee of Five, with Thomas Jefferson as its principal author. Congress debated and revised the Declaration, finally approving it on July 4.
This is a time when we as Americans should all be thankful and celebrate the independence that we do have in our country. Be safe this week in all your travels and celebrations.
