The first, local Flag Day observances came after the Civil War and eventually a federal law designated June 14 as Flag Day in 1949, under World War I combat veteran Harry Truman. He declared in a proclamation the next year that the U.S. flag symbolizes freedom and “protection from tyranny.”

Military leaders, veterans, and civic voices gather at Mount Vernon to mark Army’s 250th and launch a campaign urging Americans to serve their country.

Flag Day 2025 is expected to be observed with a massive military parade in Washington, D.C. — and hundreds of "No Kings" protests nationwide. Saturday also marks the 250th anniversary of the U.S. Army. Utah's Army-connected organizations will host an "Army birthday party" at Fort Douglas in Salt Lake City.
