LGBT History Month
The first Rainbow Flag was designed in 1978 by Gilbert Baker, a San Francisco artist, who created the flag in response to a local activist's call for the need of a community symbol.
Since that time there has been various versions of the flag for different causes. It is particularly associated with the gay community after the November 1978 assassination of San Francisco Mayor George Moscone and openly gay supervisor Harvey Milk and the subsequent lenient sentence given to their killer.
International Day Against Homophobia & Transphobia (IDAHO)
IDAHO is celebrated every May 17th. It recognises that in over 80 countries in the world homosexuality is illegal. In seven of them it can be punishable by death. The date was chosen to commemorate the World Health Organization's decision to remove homosexuality from the list of mental disorders in 1990.
