Remembrance Day – also known as Poppy Day, Armistice Day (the event it commemorates) or Veterans Day – is a Commonwealth holiday to commemorate the sacrifices of members of the armed forces and of civilians in times of war, specifically since the First World War.
It is observed on 11 November to recall the end of World War I on that date in 1918 (major hostilities of World War I were formally ended “at the 11th hour of the 11th day of the 11th month” of 1918 with the German signing of the Armistice).
The day was specifically dedicated by King George V, on 7 November 1919, to the observance of members of the armed forces who were killed during war; this was possibly done upon the suggestion of Edward George Honey to Wellesley Tudor Pole, who established two ceremonial periods of remembrance based on events in 1917.
(Note that “at the 11th hour”, refers to the passing of the 11th hour, i.e. 11:00 am.)
In the United Kingdom, Armed Forces’ Day (formerly Veterans’ Day) is a separate commemoration, celebrated for the first time on 27 June 2009.
