The International Day of Peace celebrates the power of global solidarity for building a peaceful and sustainable world.

This has never been so important at a time of unprecedented challenges. New forces of division have emerged, spreading hatred and intolerance. Terrorism is fuelling violence, while violent extremism seeks to poison the minds of the vulnerable and young. In the poorest and least-developed parts of the world, climate-related natural disasters are compounding existing fragility, increasing forced migration and heightening the risk of violence.

The barriers to peace are complex and steep — no one country can solve them alone. Doing so requires new forms of solidarity and joint action, starting as early as possible.

Establishing a culture of peace and sustainable development are at the heart of UNESCO’s mandate. Training and research in sustainable development are among the priorities, as well as human rights education, skills for peaceful relations, good governance, Holocaust remembrance, the prevention of conflict and peacebuilding.


“The ideals of peace and universal rights are challenged and violated on a daily basis. There are numerous obstacles to their realization. All kinds of challenges test our ability to build a world of harmony, understanding and peaceful coexistence: social and economic inequalities, which lead to distress and poverty; climate change, which gives rise to new conflicts; and the population explosion, which creates new tensions. Forms of populism and extremism are also spreading all over the world.

To overcome these challenges, we must act collectively and build the edifice of peace brick by brick. That is the whole aim of the United Nations 2030 Agenda for Sustainable Development, which calls for concerted action to achieve 17 Sustainable Development Goals, all of which contribute to a more just and peaceful world by, inter alia, combating poverty, hunger and gender inequality, promoting education, defending justice and committing to a healthy environment.”

— Audrey Azoulay, Director-General of UNESCO

Why are International Days important? They provide unique opportunities to transmit UNESCO values to the world.


International days also provide a unique opportunity to engage citizens on global issues, to mobilise political will and resources to address these problems, but also to celebrate and reinforce the achievements of humanity as well as remember some of our darkest times as they guide us towards building a better world.

The United Nations International Days are for everyone, all around the globe. Because they are open, you can have an important role to play in them. NGOs, universities, schools, press and more will be putting together campaigns, events, and calls to action worldwide to provide further opportunities to engage, learn, and transmit the values and knowledge associated with each International Day. They serve as an important vehicle to connect the local to the international.

At their root, UN International Days contribute to the achievement of the purposes of the UN Charter and promote awareness of and action on important political, social, cultural, humanitarian or human rights issues. International days are at the heart of the United Nations Charter. They work to reaffirm faith in fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women to practice tolerance and live together in peace with one another as neighbours, and to unite our strength to maintain international peace and security.
