International Literacy Day is an international observance, celebrated each year on 8 September, that was declared by UNESCO on 26 October 1966 at the 14th session of UNESCO’s General Conference. It was celebrated for the first time in 1967. Its aim is to highlight the importance of literacy to individuals, communities and societies. Celebrations take place in several countries.

World Suicide Prevention Day (WSPD) is an awareness day observed on 10 September every year, in order to provide worldwide commitment and action to prevent suicides, with various activities around the world since 2003. The International Association for Suicide Prevention (IASP) collaborates with the World Health Organization (WHO) and the World Federation for Mental Health (WFMH) to host World Suicide Prevention Day. 

The International Day of Peace was established in 1981 by the United Nations General Assembly. Two decades later, in 2001, the General Assembly unanimously voted to designate the Day as a period of non-violence and cease-fire.
