The main event will be in King William's Town.
"It is our belief that through increased knowledge of human rights this will embed a culture of human rights and build a province in which the breeze of unity and social cohesion will prevail and tail the storm of disunity".
"The commemorations will this year be held under the theme "The Year of OR Tambo: Unity in action in advancing Human Rights", celebrating the contribution of national icon and hero Mr Oliver Reginald Tambo in advancing unity in the struggle for liberation".
On this day in 1960, police opened fire during a mass march against South Africa's pass laws.
According to the government, a total of 69 demonstrators were gunned down by the then apartheid police.
Sixty-nine people were killed and 180 more were wounded. "This year marks 40 years since the brutal murder of Mr Biko by the apartheid state", said the statement issued earlier this week by the President's spokesperson Dr Bongani Ngqulunga.
President Zuma will join Mrs Nontsikelelo Biko and family at his [Biko's] home town in Ginsberg, to unveil the grave site and memorial of Biko.
The South African Human Rights Commission (SAHRC) urges South Africans to celebrate diversity and unite towards combating all forms of discrimination as the country celebrates Human Rights Day tomorrow.
President Jacob Zuma is due to deliver an address at the King William's Town event to commemorate the life of Biko, who died on September 12 1977 in a prison cell in Pretoria.
"We are very humbled by this decision by the government to remember Steve Biko in this way and to bring the Human Rights Day to our town".
