In 1947, the United Nations General Assembly declared 24 October, the anniversary of the Charter of the United Nations, as which “shall be devoted to making known to the peoples of the world the aims and achievements of the United nations and to gaining their support for” its work.
“UN Day is a day on which we resolve to do more. More to protect those caught up in armed conflict, to fight climate change and avert nuclear catastrophe; more to expand opportunities for women and girls, and to combat injustice and impunity; more to meet the Millennium Development Goals.” Secretary-General Ban Ki-moon
