World War One Armistice Day Centenary. "They shall not grow old, as we that are left grow old" is the famous line from Laurence Binyon's poem from 1914. At eleven minutes past eleven o'clock local time on November eleventh 2018 Bells will ring across the world to mark the 100 year anniversary of the ending of the Great War. World War One. The war to end all wars. Armistice Day was the day the treaty was signed. ANZAC day in Australia and New Zealand marks the same anniversary.
