Bi Visibility Day (also called Celebrate Bisexuality Day & Bi Pride Day) is observed every September 23 by members of the bisexual & non-monosexual community as well as their friends, families and allies. This day is a call for the bisexual community along with their friends and supporters to recognize and celebrate bisexual history, bisexual community, bisexual culture, bisexual books, bisexual bloggers, and all the bisexual and otherwise non-monosexual people in their lives.
First observed in Johannesburg SA in 1999,this holiday is the brainchild of three veteran bisexual-identified LGBTQ campaigners: Wendy Curry of Maine, Michael Page of Florida, and Gigi Raven Wilbur of Texas. Wilbur said,
"Ever since the Stonewall rebellion, the gay and lesbian community has grown in strength and visibility. The bisexual community also has grown in strength but in many ways we are still invisible. I too have been conditioned by society to automatically label a couple walking hand in hand as either straight or gay, depending upon the perceived gender of each person."
This celebration of bisexuality in particular, as opposed to general LGBTQ events, was conceived as a response to the prejudice and marginalization of the bisexual persons by some in both the straight and mainstream Gay/Lesbian communities, especially as it relates to trans*, gender nonconforming and androgynous bisexual people and their partners.
A variety of functions happen worldwide including notable celebration across the UK, the USA, as well as Germany, Japan, New Zealand, Sweden and Taiwan. Some featured events include things suc as discussions, dinner parties and dances in Toronto, a masquerade ball in Queensland, Australia, discussion panels and question-and-answer sessions in Universities, public demonstrations and teach-ins in Paris, etc. In 2012, Berkeley, California became what is thought to be the first city in the USA to officially proclaim a day recognizing the bisexual community, when the City Council unanimously declared September 23rd as Bisexual Pride and Bi Visibility Day.
