On Memorial Day.
Remembrance Day (Australia, Canada, United Kingdom and Ireland), also known as Poppy Day (South Africa and Malta), and Armistice Day (United Kingdom, New Zealand and many other Commonwealth countries; and the original name of the holiday internationally) is a day to commemorate the sacrifice of veterans and civilians in World War I, World War II, and other wars. It is observed on November 11 to recall the end of World War I on that date in 1918. The observance is specifically dedicated to members of the armed forces who were killed during war, and was created by King George V of the United Kingdom on November 7, 1919, possibly upon the suggestion of Edward George Honey though Wellesley Tudor Pole established two ceremonial periods of remembrance based on events in 1917.[
