Remembrance Day is observed in Commonwealth Countries on November 11th to commemorate the end of World War One hostilities which ended at the 11th hour of the 11th day of the 11th month, 1918.

The equivalent day in the United States is not Memorial Day as you might expect. Memorial Day (the last Monday in May) commemorates those who died in military service.

Veterans day previously known as Armistice Day is observed on November 11th each year to honor persons who served in the United  States Army.
