Every year on the May 17 people all over the world celebrate the International Day Against Homophobia, Biphobia, and Transphobia (IDAHOT). This is one of the most important days for the LGBT community. On May 17, 1990, the World Health Organization (WHO) excluded homosexuality from the international classification of diseases. This marked an immense step towards equality. Since 2004, people celebrate this day worldwide to draw attention to issues of discrimination and violence against LGBT people. This year, a variety of events dedicated to honoring May 17 happened in more than 130 countries, including those 37 countries in which same-sex sexual relations are prohibited by law.
