Why do we mark International Days?
International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.

International Mother Earth Day 2025 22 April
Mother Earth is a common expression for the planet earth in a number of countries and regions, which reflects the interdependence that exists among human beings, other living species and the planet we all inhabit.
International Mother Earth Day is celebrated to remind each of us that the Earth and its ecosystems provide us with life and sustenance.
This Day also recognizes a collective responsibility, as called for in the 1992 Rio Declaration, to promote harmony with nature and the Earth to achieve a just balance among the economic, social and environmental needs of present and future generations of humanity.

Freedom Day 2025 27 April
Freedom Day is the commemoration of the first democratic elections held in South Africa on 27 April 1994. These were the first post-apartheid national elections to be held in South African where anyone could vote regardless of race.
Although we have made remarkable progress since 1994, the spectre of inequality, poverty and unemployment remains one of the most glaring impediments to South Africa’s goal of national unity and social cohesion.
We also dare not forget the terrible past from which we have come, nor should we forget the many sacrifices made by patriots to ensure our democracy and freedom. Our history abounds with selfless patriots who paved the way for a democratic and free South Africa.
This year marks the 150th anniversary of struggle icon and human rights campaigner Charlotte Maxeke. She and other selfless women of her generation fought against oppression at a time when such defiance was met with unrelenting force.
