Veterans Day traces its history back to World War I, and a ceasefire signed by the Allies and Germany that went into effect on the 11th hour, of the 11th day, of the 11th month. The holiday has been observed on Nov. 11 in honor of that agreement. The U.S. Department of Veterans Affairs (VA) said the day is meant to be, “A celebration to honor America’s veterans for their patriotism, love of country, and willingness to serve and sacrifice for the common good.”
