In the United States, Flag Day (more formally, National Flag Day), is celebrated on June 14. It commemorates the adoption of the flag of the United States, which happened that day by resolution of the Second Continental Congress in 1777.
In 1916, Woodrow Wilson issued a proclamation that officially established June 14 as Flag Day; in August 1949, National Flag Day was established by an Act of Congress.
Flag Day is not an official federal holiday, though on June 14, 1937, Pennsylvania became the first (and only) U.S. state to celebrate Flag Day as a state holiday.

Here are a couple of books in my collection that we will be reading to celebrate this holiday:
The Story of the Star-Spangled Banner - Natalie Miller
This is a Cornerstone of Freedom book. These books are excellent for teaching history to elementary aged children.
The Pledge of Allegiance - Scholastic
This is an excellent book with the correct words to the Pledge (ahem) and lots of facts about the American flag.
