International Day Against Homophobia, Biphobia and Transphobia

The International Day Against Homophobia, Biphobia and Transphobia (IDAHOBIT) is held each year on 17 May. It commemorates the World Health Organisation’s decision in 1990 to remove homosexuality from its International Classification of Diseases.
IDAHOBIT fosters a global moment for collective action, awareness, solidarity, and visibility, bringing together individuals, organisations, and governments under a shared global theme to highlight issues faced by LGBTQIA+ people around the world. The theme for this year’s IDAHOBIT is ‘The Power of Communities’.
Look out for the Pride flag flying over Sussex House from 15-19 May in celebration of IDAHOBIT.
David Ruebain, Pro-Vice-Chancellor for Culture, Equality and Inclusion, said: ‘This year has seen a number of developments in the political and legal landscape in the UK and around the world. Our LGBTQ+ staff and students are valued members of the university community, and we will continue to work for a supportive and inclusive environment on our campus for everyone.’
What’s on
In honour of IDAHOBIT, the LGBTQ+ Staff Network is planning a queer history walk followed by a drag show. These will take place on 30 May in Brighton. Find out more and book your place.
