Remembrance Day (also known as Poppy Day owing to the tradition of wearing a remembrance poppy) is a memorial day observed in Commonwealth member states since the end of the First World War to honour armed forces members who have died in the line of duty. Following a tradition inaugurated by King George V in 1919, the day is also marked by war remembrances in many non-Commonwealth countries. In most countries, Remembrance Day is observed on 11 November to recall the end of First World War hostilities. Hostilities formally ended “at the 11th hour of the 11th day of the 11th month” of 1918, 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 am.) The First World War officially ended with the signing of the Treaty of Versailles on 28 June 1919.
