The International Day Against Homophobia, Biphobia and Transphobia (IDAHOBIT) is observed on 17 May and aims to coordinate international events that raise awareness of LGBTQ rights violations and stimulate interest in LGBTQ rights work worldwide. By 2016, the commemorations had taken place in over 130 countries.

The founders of the International Day Against Homophobia, as it was originally known, established the IDAHO Committee to coordinate grassroots actions in different countries, to promote the day and to lobby for official recognition on May 17. That date was chosen to commemorate the decision to remove homosexuality from the International Classification of Diseases of the World Health Organization (WHO) in 1990.
