Established by the Council of Europe in December 2001 to celebrate Europe's rich linguistic heritage. Celebrated annually on 26 September across member states. Activities include language workshops, fairs, competitions, and cultural events. Aims to raise awareness of the importance of language learning for cultural understanding and mobility. Encourages recognition of the over 200 languages spoken in Europe, including regional and minority languages. Schools, universities, and cultural institutions host events to foster multilingual communication and cooperation.

Recognized by the United Nations General Assembly in December 2013, the day marks the first UN high-level meeting on nuclear disarmament held in 2013. It honors Stanislav Petrov, whose actions in 1983 prevented a potential nuclear crisis. The observance aims to educate the public about the threats posed by nuclear arsenals and the need for disarmament. Governments, civil society groups, and individuals are encouraged to support initiatives toward a nuclear-weapons-free world. Annual events include seminars, conferences, and awareness campaigns highlighting disarmament progress and challenges. The day reinforces global commitment to peace, security, and the long-term goal of eliminating nuclear weapons.
