The International Day Against Nuclear Tests is observed annually on August 29. This day aims to raise awareness about the harmful effects of nuclear weapons testing on people and the environment. It promotes global efforts to achieve a world free of nuclear weapons and encourages nations to adhere to treaties that prohibit nuclear testing. Established by the United Nations in 2009, the day commemorates the importance of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). This treaty seeks to ban all nuclear explosions, thereby contributing to global peace and security. Events and activities are organized worldwide to educate the public and advocate for disarmament.
