Explaining 'Flag Day' in the U.S.

Today is Flag Day, one of 20 days Congress says the American flag should be flown. The celebration traces its birth to the Second Continental Congress, which, on June 14, 1777, passed a resolution that the flag of these United States "be thirteen stripes, alternate red and white" and "the union be thirteen stars, white in a blue field, representing a new constellation. It wasn't until 1949 that President Harry Truman set aside June 14 as the Flag Day.
