Answer: March 1
Notes: World Civil Defence Day is celebrated annually on March 1 to raise awareness about civil defence strategies and people's protection. The day highlights the importance of civil defence in safeguarding people and property from accidents, natural disasters, and crises. It was first observed in the 20th century during times of social, technological, and political upheaval, especially due to nuclear weapons concerns. The United Nations created the International Civil Defence Organisation to coordinate global civil defence efforts. The ninth General Assembly in 1990 designated March 1 as World Civil Defence Day.
