United Nations: International Day of Peace, 21 September 2026
On 21 September 2026, the world celebrates the International Day of Peace, established by the United Nations General Assembly in 1981 and designated, since 2001, as a period dedicated to non-violence and ceasefire.
The theme for 2026 is “Invest in Peace – For Everyone, Everywhere, Every Day”, calling on individuals, institutions and communities to recognise peace as a shared responsibility and to contribute to its promotion in everyday life.
The United Nations emphasises that peace is more than the absence of war. It is closely connected with safety, dignity, equal opportunities and cooperation, and is essential for addressing the challenges faced by societies worldwide. The 2026 observance therefore places particular attention on the “everyday architects of peace”: people who promote local action, strengthen social cohesion and contribute to building lasting peace from the ground up.
Peace is not created only through international negotiations or political agreements. It is also built in classrooms, neighbourhoods and communities, wherever people meet with openness, dialogue and respect. In this sense, promoting peace is closely connected with the protection of human rights, equality, dignity and non-discrimination.
The United Nations also highlights the importance of peacebuilding. Established in 2005, the UN Peacebuilding Commission, together with the Peacebuilding Support Office and the Peacebuilding Fund, supports initiatives aimed at conflict prevention and resolution, justice, reconciliation, human rights and gender equality. The Peacebuilding Fund has supported projects in more than 70 countries.
The 2026 International Day of Peace invites everyone to take concrete steps in support of peace: helping others, speaking out for positive change, creating spaces for dialogue and using communication platforms to promote messages of peace and hope. These everyday actions contribute to the broader effort to build more peaceful, inclusive and just societies.
The International Day of Peace is therefore an opportunity to reaffirm that peace and human rights are mutually reinforcing, and that building a culture of peace requires the participation of everyone, everywhere, every day.
