Flag Day is celebrated in the United States annually on June 14 to honor the Star-Spangled Banner that represents the country.

The day marks the official adoption of the Stars and Stripes by the Second Continental Congress in 1777. Former President Woodrow Wilson had proclaimed June 14 as the day to "rededicate ourselves to the nation."

The First Flag Act declared that the new flag would have "13 stripes alternate red and white: that the union be thirteen stars, white in a blue field, representing a new constellation." Wilson wanted Americans to mark Flag Day to leave behind "every thought that is not worthy of our fathers' first vows in independence, liberty and right," and instead "stand with united hearts, for an America which no man can corrupt, no influence draw away from its ideals, no force divide against itself."
