Anzac Day is a national day of remembrance in Australia that commemorates all Australians and New Zealanders who served and died in all wars, conflicts, and peacekeeping operations. Anzac stands for Australian and New Zealand Army Corps, the troops who fought at Gallipoli in the Ottoman Empire during World War I. Celebrated annually on April 25, this significant day has been nationally observed in Australia since 1916.

On Anzac Day, dawn services, marches, and remembrance services are held at war memorials around the country. The commemoration typically begins with a 'dawn service' at the break of the day, reflecting the same time that the original Anzac troops, the 'Anzacs,' landed in Gallipoli in 1915. This is followed by the Last Post, a minute's silence, and then reveille, a bugle call used to wake military personnel at sunrise.

Over time, Anzac Day has evolved to embrace the memory of all those who have died in military and peacekeeping operations for their countries. It serves as a solemn day of reflection about the cost of war and the indomitable spirit of those who serve. Known for their courage, endurance, and mateship, the Anzacs hold a special place in the hearts of Australians and New Zealanders, and Anzac Day continues to be revered as one of the most important national occasions in both countries.
