International Day Against Homophobia and Transphobia (IDAHO or IDAHOT) are widely recognized as an essential feature in the international LGBT rights calendar. In the 9th edition, in 2013, commemorations took place in almost 120 countries, in all world regions. The day aims to coordinate international events that raise awareness of LGBT rights violations and stimulate interest in LGBT rights work worldwide. IDAHO's date was chosen to commemorate the decision to remove homosexuality from the International Classification of Diseases of the World Health Organization (WHO) in 1990. The original founders of the International Day Against Homophobia (or "IDAHO"), established the IDAHO Committee to co-ordinate grass-roots actions in different countries, to promote the day and to lobby for official recognition of May 17.
