Nelson Mandela International Day, also known as Mandela Day, is an international day in honour of Nelson Mandela, celebrated on 18. July 2021. On this day, Mandela was born in 1918, so it celebrates his birthday. The day was officially declared by the United Nations in November 2009, with the first UN Mandela Day held on 18 July 2010.
Mandela Day is not meant as a public holiday, but as a day to honour the legacy of Nelson Mandela, South Africa's former President, and his values, through volunteering and community service. The day is a global call to action that celebrates the idea that each individual has the power to transform the world, the ability to make an impact.
Nelson Mandela, who died in 2013, was a South African anti-apartheid revolutionary, politician and philanthropist who served as President of South Africa from 1994 to 1999. He was South Africa's first black chief executive, and the first elected in a fully representative democratic election. His government focused on dismantling the legacy of apartheid through tackling institutionalised racism, poverty and inequality, and fostering racial reconciliation. (With material from: Wikipedia)
