Australians and New Zealanders recognise 25 April as a ceremonial occasion to reflect on the cost of war and to remember those who fought and lost their lives for their country. Commemorative services and marches are held at dawn, the time of the original landing, mainly at war memorials in cities and towns across both nations and the sites of some of Australia and New Zealand's more-recognised battles and greatest losses, such as Villers-Bretonneux in France and Gallipoli in Turkey.
One of the traditions of Anzac Day is the 'gunfire breakfast' (coffee with rum added) which occurs shortly after many dawn ceremonies, and recalls the 'breakfast' taken by many soldiers before facing battle. Later in the day, ex-servicemen and ex-servicewomen meet and join in marches through the major cities and many smaller centres.
The restoration of Poland's independence was gradual. The 11 November date chosen is the one on which Józef Piłsudski assumed control of Poland. The holiday was constituted in 1937 and was celebrated only twice before World War II. After the war, the communist authorities of the People's Republic removed Independence Day from the calendar, though reclamation of independence continued to be celebrated informally on 11 November. The holiday was officially replaced by the National Day of Poland's Revival, celebrated on the 22 July anniversary of the PKWN Manifesto. As Poland emerged from Soviet-influenced communism in 1989, the original holiday—on its original 11 November date—was restored.
The date corresponds to the date of other countries' Remembrance Day, Armistice Day, or Veteran's Day. All of these holidays and Polish Independence Day are indirectly related because they all emerged from the circumstances at the end of World War I.
