International Day Against Homophobia, Biphobia and Transphobia is observed on May 17 and aims to coordinate international events that raise awareness of LGBT rights violations and stimulate interest in LGBT rights work worldwide.
The International Day Against Homophobia, Transphobia and Biphobia was created in 2004 to draw the attention to the violence and discrimination experienced by lesbian, gay, bisexual, transgender, intersex people and all other people with diverse sexual orientations, gender identities or expressions, and sex characteristics.
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.
