Remembrance Sunday 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 recognised as special days for war remembrances in many non-Commonwealth countries. Remembrance Sunday is observed on the nearest Sunday to Armistice day 11th 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 am) World War I officially ended with the signing of the Treaty of Versailles on 28 June 1919.

The day was specifically dedicated by King George V on 7 November 1919 as a day of remembrance for members of the armed forces who were killed during World War I. 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.

The red remembrance poppy has become a familiar emblem of Remembrance Day due to the poem "In Flanders Fields". These poppies bloomed across some of the worst battlefields of Flanders in World War I, their brilliant red colour an appropriate symbol for the blood spilled in the war.

This year's remembrance parade will take place on Sunday 11th November 2018
