About International Day Against Homophobia, Transphobia and Biphobia
A day to recognize the progress made in the struggle for LGBT+ equality and recommit ourselves to working with the LGBT+ community to fight for full equality around the world. Created in 2004 to draw the attention of policymakers, opinion leaders, social movements, the public and the media to the violence and discrimination experienced by LGBTI people internationally.
The date of May 17th was specifically chosen to commemorate the World Health Organization’s decision in 1990 to declassify homosexuality as a mental disorder.
The Day represents a major global annual landmark to draw the attention of decision-makers, the media, the public, corporations, opinion leaders, local authorities, etc. to the alarming situation faced by people with diverse sexual orientations, gender identities or expressions, and sex characteristics.
The International Day against Homophobia, Transphobia and Biphobia has received official recognition from several States, international institutions such as the European Parliament, and by countless local authorities. Most United Nations agencies also mark the Day with specific events.
It is currently celebrated in more than 130 countries worldwide — including 37 where homosexuality is illegal.
To mark this date, you might do some research to learn about the contributions of LGBTQ people — both to human rights and society in general. Or find an LGBTQ organization or event near your hometown. Reach out to LGBTQ friends or relatives to let them know you support them. And visit May17.org for more information.
