Zero Discrimination Day is an annual day celebrated by the United Nations (UN) and other international organisations. The day aims to promote equality before the law and in practice throughout all of the member countries of the UN. The day was first celebrated on March 1, 2014, and was launched by UNAIDS Executive Director Michel Sidibé on 27 February of that year with a major event in Beijing. The UN Development Programme also paid tribute in 2017 to LGBTI people with HIV/AIDS who face discrimination.

On Zero Discrimination Day, 1 March, we celebrate the right of everyone to live a full and productive life—and live it with dignity. Zero Discrimination Day highlights how people can become informed about and promote inclusion, compassion, peace and, above all, a movement for change. Zero Discrimination Day is helping to create a global movement of solidarity to end all forms of discrimination.

On Zero Discrimination Day this year, UNAIDS is challenging the discrimination faced by women and girls in all their diversity in order to raise awareness and mobilize action to promote equality and empowerment for women and girls.
