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.
In South Africa, Remembrance Day is not a public holiday. Commemoration ceremonies are usually held on the nearest Sunday, at which the “Last Post” is played by a bugler followed by the observation of a two-minute silence. Ceremonies to mark the event in South Africa are held at the Cenotaph in Cape Town, and in Pretoria at the Voortrekker Monument cenotaph and the War Memorial at the Union Buildings. Many high schools hold Remembrance Day services to honour the past pupils who died in the two World Wars and the Border war. In addition, the South African Legion of Military Veterans holds a street collection on the nearest Saturday to gather funds to assist in welfare work among military veterans. https://en.wikipedia.org/wiki/Remembrance_Day#South_Africa
