For the information of overseas readers, 25 April 2012 is Anzac Day in Australia and New Zealand, the national day of remembrance. The day is named after a combined military force of those two countries, the Australian and New Zealand Army Corps, which participated in the first major military action of those two countries in 1915 at Gallipoli in Turkey. The Gallipoli campaign, although a military failure, is considered to be a significant event in the founding of the Australian nation, spirit and identity. Anzac Day is marked by dawn services, including one at Gallipoli, by marches in capital cities and towns, and by numerous remembrance ceremonies. It is the most sacred secular day in Australia and New Zealand, the nations honouring their war dead and thanking those surviving, from all wars.
