About International Day of Peace

International Day of Peace is one of the international days on the United Nations list. The UN uses these days to draw attention to an issue and to what people around the world are doing about it.

In 2027 it falls on a Tuesday; in 2028 it’s on Thursday 21 September, and in 2029 on Friday 21 September. Also in September 2027: Zero Emissions Day (21 Sep), Youth Day (Paraguay) (21 Sep) and Arbor Day (Brazil) (21 Sep). From this page you can add it to your calendar, get an email before it, share the countdown, or show it full screen.

How we work out the date
It’s on 21 September every year, as set by the United Nations.
