Nelson Mandela has many accolades. He’s an iconic figure that triumphed over South Africa’s apartheid regime. He was a human rights lawyer, a prisoner of conscience, and an international peacemaker. And he was the first democratically elected president of a free South Africa (no biggie). So you see why the United Nations General Assembly would want to celebrate his life. Commemorated on July 18 — Nelson Mandela’s birthday — Nelson Mandela International Day celebrates the idea that each individual has the power to transform the world and the ability to make an impact. So, in honor of his 67 years of public service, the Nelson Mandela Foundation and the U.N. ask that you spend 67 minutes of your time helping others.
