The International Day Against Homophobia (IDAHO) is an event designed to heighten awareness of homophobia in societies across the globe. The event is now in its fourth year. Unlike GLBT Pride, celebrated globally in June, whose mission to foster a healthy acceptance of homosexuality is carried out with a theme of increasing pride in the gay community, IDAHO is saying that it is society that must end homophobia. IDAHO acknowledges that homophobia exists around the world - even state-sponsored homophobia - and its impact affects all of society negatively.

The event is the brainchild of Louis-Georges Tin, a professor and author of a number of books, including the Dictionary of Homophobia. Tin, the founder of IDAHO, a Paris-based organization, has also proposed a United Nations resolution declaring that homosexuality should no longer be considered a crime anywhere in the world.

The day has been recognized by governments worldwide, including the European Parliament, Belgium, the United Kingdom and Mexico and several provinces of Canada, Brazil and Spain. The government of Costa Rica recently announced support for the day. Events are held each year in over 50 countries worldwide.

In the United Kingdom, London organizers plan to mark the day by honoring Jody Dobrowski, who was beaten to death in a homophobic attack.

Mariela Castro, President Raul Castro's daughter, is organizing Cuba's second anti-homophobic festival. The weeklong festival's program of movie screenings, debates and book fairs will culminate with IDAHO. Castro has also proposed legal recognition of same-sex couples to communist party officials.

In previous years, activist in Japan delivered letters to the embassies of some of the eighty countries where homosexuality is a crime. Protests have been organized in Latin American and Europe. In the US, a minute of silence marked the day.

The date of the event was chosen because it is the date homosexuality was removed from the World Health Organization's (WHO) International Classification of Diseases in 1990. Coincidently, on May 17th, 2004 Massachusetts became the first State to recognize same-sex marriages.
