WHAT IS THE INTERNATIONAL DAY OF PEACE?
The International Day of Peace ("Peace Day") is observed around the world each year on 21 September. Established in 1981 by unanimous United Nations resolution, Peace Day provides a globally shared date for all humanity to commit to Peace above all differences and to contribute to building a Culture of Peace.
This is a long-established universal website that serves all involved in Peace Day, beginning annually with the 100-day Countdown.
Let us all create Peace Day every day!

2026 Theme: Invest in Peace - For Everyone, Everywhere, Every Day
Under the theme Invest in Peace: For Everyone, Everywhere, Every Day, this year’s International Day of Peace honours the 'everyday architects of peace'—people driving local action, laying the groundwork for stability, and building a lasting peace from the ground up.
Remember, peace isn’t just built in conference rooms—it is shaped by everyone, everywhere, every day.
Show us how you're building the architecture of peace and justice using #InvestInPeace.
