ANZAC Day is a national holiday in Australia and New Zealand that is observed on April 25th. It commemorates the soldiers who fought and died in the Australian and New Zealand Army Corps (ANZAC) during World War I, as well as all those who have served in the military.

The history of ANZAC Day goes back to the landing of Australian and New Zealand troops at Gallipoli, Turkey, on April 25th, 1915. The ANZAC forces were part of a larger Allied campaign to capture the Ottoman Empire's capital city of Constantinople. The campaign was ultimately unsuccessful, but the ANZAC soldiers gained a reputation for their bravery and determination in the face of heavy casualties.

ANZAC Day is observed in a variety of ways in Australia and New Zealand. The day typically begins with a dawn service, which includes a reading of the Ode of Remembrance and the playing of the Last Post. There may also be parades, wreath-laying ceremonies, and other commemorative events throughout the day.

One of the most important ANZAC Day traditions is the baking and sharing of ANZAC biscuits. These biscuits were first made during World War I and were sent to soldiers as a nutritious and long-lasting snack. Today, they are a symbol of remembrance and are often sold to raise funds for veterans' organizations.

Overall, ANZAC Day is a day of remembrance and reflection for Australians and New Zealanders. It is a time to honor the sacrifices made by the soldiers who served in the ANZAC forces and to remember the impact of war on the nation.
