Here in the United States we don't call or celebrate Remembrance day or Poppy day. We call it Veterans Day.
Americans don't typically wear poppies on November 11 (Veterans Day), which honors all living veterans. Instead, they wear the symbolic red flower on Memorial Day—the last Monday in May—to commemorate the sacrifice of so many men and women who have given their lives fighting for their country.
United States
Veterans Day is observed in the United States on 11 November, and is both a federal holiday and a state holiday in all states. However, the function of the observance elsewhere is more closely matched by Memorial Day in May. In the United States, and some other allied nations, 11 November was formerly known as Armistice Day; in the United States it was given its new name in 1954 at the end of the Korean War to honour all veterans. Veterans Day is observed with memorial ceremonies, salutes at military cemeteries, and parades.
