The International Day of Peace, observed every year on September 21, calls on us to strengthen the ideals of peace within and among nations and peoples. In a world marked by conflict, inequality, and discrimination, it is a reminder of our urgent responsibility to foster solidarity, advance disarmament, nurture empathy, and build sustainable peace for all.

On this day, let us remember: peace must always be created together and for everyone.

Join peace activities taking place worldwide.
