Remembrance Day is one of the most important days on our commemorative calendar. It's a day when we acknowledge those who died or suffered while serving in wars, conflicts and peace operations. Remembrance Day is held on 11 November each year. This is the anniversary of the Armistice of 1918 that ended fighting in World War I. The war didn't officially end until 28 June 1919 with the Treaty of Versailles. People in Australia and many other countries observe one minute's silence at the 11th hour of the 11th day of the 11th month because that's when the Armistice came into effect. It's a time to honour all personnel who died or suffered in the service of Australia.
