Anzac Day is a national day of remembrance in Australia and New Zealand that broadly commemorates all Australians and New Zealanders "who served and died in all wars, conflicts, and peacekeeping operations" and "the contribution and suffering of all those who have served".
Observed on 25 April each year, Anzac Day was originally devised to honour the members of the Australian and New Zealand Army Corps (ANZAC) who served in the Gallipoli campaign, their first engagement in the First World War (1914–1918).
Anzac Day marks the anniversary of the first campaign that led to major casualties for Australian and New Zealand forces during the First World War.
The acronym ANZAC stands for Australian and New Zealand Army Corps, whose soldiers were known as Anzacs.
Anzac Day remains one of the most important national occasions of both Australia and New Zealand.
