Anzac Day occurs annually on April 25th to commemorate Australian and New Zealand soldiers killed in war and to honor returned servicemen. It marks the anniversary of when Australian and New Zealand troops landed at Gallipoli Peninsula in 1916 during World War I. The red poppy has become a symbol of remembrance for those who died in war. Dawn services are held each year on Anzac Day where people gather at local war memorials before dawn to honor those who served.
