Remembrance Day (also known as Poppy Day or Armistice Day) is a memorial day observed in Commonwealth countries since the end of World War I to remember the members of their armed forces who have died in the line of duty. This day, or alternative dates, are also recognized as special days for war remembrances in many non-Commonwealth countries. Remembrance Day is observed on 11 November to recall the end of hostilities of World War I on that date in 1918. Hostilities formally ended "at the 11th hour of the 11th day of the 11th month," in accordance with the Armistice, signed by representatives of Germany and the Entente between 5:12 and 5:20 that morning. ("At the 11th hour" refers to the passing of the 11th hour, or 11:00 a.m.) World War I officially ended with the signing of the Treaty of Versailles on June 28, 1919.
The poppy of wartime remembrance is Papaver rhoeas, the red-flowered corn poppy. This poppy is a common weed in Europe and is found in many locations, including Flanders, the setting of the famous poem "In Flanders Fields," by the Canadian surgeon and soldier John McCrae. In Canada, the United Kingdom, Australia, South Africa and New Zealand, artificial poppies (plastic in Canada, paper in the UK, Australia, South Africa, Malta and New Zealand) are worn to commemorate those who died in war. This form of commemoration is associated with Remembrance Day, which falls on November 11. In Canada, Australia and the UK, poppies are often worn from the beginning of November through to the 11th, or Remembrance Sunday if that falls on a later date (November 13 in 2011). In New Zealand and Australia, soldiers are commemorated on ANZAC day (April 25), although the poppy is still commonly worn around Remembrance Day. Wearing of poppies has been a custom since 1924 in the United States. Miss Moina Michael of Georgia is credited as the founder of the Memorial Poppy in the United States. from Wiki.
