Founded in Nebraska in 1872 by J. Sterling Morton, Arbor Day was born out of agricultural survival. Early Great Plains settlers desperately needed trees to serve as windbreaks, prevent topsoil erosion, and provide shade, resulting in over one million seedlings planted on the very first day.

On June 14, 1777, the Second Continental Congress resolved that the flag of the United States be thirteen stripes, alternate red and white, with thirteen white stars in a blue field. Decades of grassroots campaigns led Woodrow Wilson and Harry Truman to codify national Flag Day.

Designated by Congress on December 18, 2001, Patriot Day calls on all Americans to observe a moment of silence at 8:46 a.m. Eastern Time, when Flight 11 struck the North Tower. US flags fly at half-staff to honor the nearly 3,000 lives lost and heroic first responders.
