In the United States, Flag Day is celebrated on June 14. It commemorates the adoption of the flag of the United States, which happened on that day in 1777 by resolution of the Second Continental Congress. The United States Army also celebrates the Army Birthday on this date; Congress adopted "the American continental army" after reaching a consensus position in the Committee of the Whole on June 14, 1775.
Father's Day is a celebration honoring fathers and celebrating fatherhood, paternal bonds, and the influence of fathers in society. Many countries celebrate it on the third Sunday of June, though it is also celebrated widely on other days by many other countries. Father's Day was created to complement Mother's Day, a celebration that honors mothers and motherhood.
