Celebrate Bisexuality Day / Bi Visibility Day

1. The Story Behind the Day

A day created because bi people were being missed

Bisexual people have long been part of LGBTQ+ communities and movements, yet bi experiences can disappear in public narratives that divide sexuality into straight or gay. Bi Visibility Day emerged as a deliberate response to that erasure.

According to the Bi Visibility Day origin history, the annual celebration began in 1999, created by Wendy Curry, Michael Page and Gigi Raven Wilbur. The project describes the original name as International Celebrate Bisexuality Day. September 23 became the recurring date and was marked again in subsequent years rather than remaining a one-off event.

BiNet USA also records Curry, Page and Wilbur as the organisers of the first 1999 Celebrate Bisexuality Day and treats 23 September as the historical date associated with that organising.

Why the name changed in some places

Community observances often gather multiple names as they travel. “Celebrate Bisexuality Day” foregrounds celebration and pride. “Bi Visibility Day” foregrounds recognition and the problem of erasure. The Bi Visibility Day history project notes that the latter name grew especially through UK organising and later spread more widely.

Calendar 5.0 preserves both names because the variation is part of the history. There is no need to invent a single global authority that settled the terminology.

Visibility is about more than being seen

A person can be openly bi and still have their identity repeatedly overwritten. Someone in a different-gender relationship may be assumed straight; someone in a same-gender relationship may be assumed gay or lesbian. Single people can be told they cannot know. Bi people can also face stereotypes that they are indecisive, unfaithful or temporarily “on the way” to another identity.

Visibility therefore means being recognised accurately, not simply being visible in public.

Bi is a broad family of identities

People use “bi” in different ways. For many, it describes attraction to more than one gender. Some use bisexual, some biromantic, and some use other multisexual labels such as pansexual alongside or instead of bi.

The history project also explains why “bi visibility” can be more inclusive than a narrow reading of “bisexuality”: romantic and sexual orientation do not always line up in the same way for every person. The important editorial principle is to let people choose their language.

2. What Can We Learn?

A partner does not define a person's orientation

One of the most persistent forms of bi erasure is reading identity directly from a current relationship. This treats bisexuality as a behaviour rather than an orientation.

A bi woman dating a man does not become straight. A bi man dating a man does not become gay. A non-binary bi person may not fit those gendered assumptions at all. Relationship status can change; identity does not have to be recalculated from the outside each time.

That lesson is simple but has practical consequences for forms, healthcare conversations, data collection and community spaces.

Belonging should not require proof

Bi people can experience a peculiar double gatekeeping: treated as not straight enough for heterosexual spaces and not queer enough for LGBTQ+ spaces. People may be asked about relationship history or sexual experience to justify a label that others accept without interrogation.

Inclusive communities resist that impulse. Identity is not an application process.

Visibility and privacy both matter

A visibility day can encourage public storytelling, but disclosure should remain voluntary. Someone may be open to friends and not at work. Another person may use a label privately while deciding what it means to them. Others live in places where disclosure creates real risk.

A movement for visibility succeeds when people have more freedom to be known, not when everyone feels obliged to be public.

Intersectionality changes the experience of bi inclusion

Bi people can also be disabled, neurodivergent, trans, non-binary, racialised, religious, migrants or members of many other communities. Those identities are not separate compartments.

For a neurodivergent bi person, for example, communication differences or dependence on family/support systems may affect privacy, dating, healthcare or access to community. The correct response is not to treat bisexuality as a product of neurodivergence. It is to make support and LGBTQ+ spaces more accessible.

3. What Needs to Change?

Stop using binary relationship assumptions in services

Healthcare, counselling, sexual-health education and intake forms often infer orientation from the gender of a current partner. That can produce poor questions and missed information.

Services should ask what is actually relevant. If sexual-health risk information is needed, ask about practices rather than assuming them from identity. If a person provides an orientation label, record it accurately rather than rewriting it from relationship status.

Make LGBTQ+ spaces explicitly bi-inclusive

A rainbow logo does not guarantee that bi people will feel recognised. Event language, speaker line-ups and resources should include bi experiences directly rather than treating “LGBTQ+” as sufficient proof of inclusion.

That also means challenging jokes and stereotypes inside queer communities, not only in heterosexual settings.

Improve data without turning identity into a box-ticking exercise

Organisations often lack usable information because surveys force people into mutually exclusive “gay / straight” categories or combine all LGBTQ+ respondents into one small group.

Better data can reveal different experiences, but data collection should have a purpose, privacy protections and enough sample size to avoid misleading conclusions. People should understand why identity information is being requested.

Do not sexualise bisexuality

Bisexuality is sometimes treated as an invitation for invasive questions about sex, threesomes or relationship arrangements. Those assumptions can make ordinary workplace, school or healthcare interactions unsafe.

Orientation does not tell you whether someone is monogamous, polyamorous, sexually active or interested in discussing their private life. The standard should be the same respect offered to anyone else.

Recognise later self-understanding

Some people identify as bi after years in relationships that others read as heterosexual or gay. They may re-interpret earlier experiences or find language that was unavailable to them before.

Communities should leave room for that without accusing people of rewriting the past. Identity language can become clearer over time.

Bi visibility should include people outside couple-centred stories

Awareness campaigns often illustrate bisexuality through romantic couples. That can unintentionally make single, aromantic, asexual-spectrum or relationship-averse bi people less visible. Identity does not require a relationship as evidence.

Community representation can include friendship, family, work, activism, creativity and ordinary daily life. This reduces the pressure to explain bisexuality only through who someone dates.

Mental-health discussions need careful causality

Bi people may experience stigma, erasure or exclusion, and those environments can affect wellbeing. But it is important not to imply that bisexuality itself is a mental-health problem or that every bi person has the same experience.

When organisations discuss wellbeing, they should distinguish identity from the effects of discrimination and unequal access. Support should address stressors without pathologising orientation.

Inclusion language should work for trans and non-binary bi people too

Bi visibility can become overly binary when examples assume attraction is always “to men and women” and that everyone involved is cisgender. Many people use bi in ways that include attraction to more than one gender without treating gender as only two fixed categories.

Organisations do not need to police definitions. They can use language broad enough for people to describe themselves and follow the terminology used by bi-led sources and individuals.

Organisational histories should preserve bi contribution

Bisexual activists have often worked inside wider lesbian, gay, trans and queer movements. When institutional histories simplify that work into a two-category story, bi contribution can disappear even where bi people were present from the beginning.

Archives, museums, Pride organisations and employers can review how they name past participants and campaigns. Accurate historical credit is another form of visibility, and it avoids making today's inclusion appear newer than it really is.

4. What Can You Do?

5. Explore the Movement

The Bi Visibility Day history documents the 1999 creation of International Celebrate Bisexuality Day by Wendy Curry, Michael Page and Gigi Raven Wilbur and explains the later growth of the “Bi Visibility Day” name. BiNet USA's heritage page provides an additional community-history record and explicitly distinguishes Pride Day history from related histories such as the bisexual pride flag.

That distinction matters because symbols, observances and organisations overlap without being identical. Michael Page is also associated with the bisexual pride flag, but the flag and the September 23 observance have separate histories.

Related Calendar 5.0 observances include LGBTQ Pride Month, International Day Against Homophobia, Biphobia and Transphobia, International Non-Binary People's Day, Transgender Day of Visibility and Zero Discrimination Day.

6. Why This Day Matters to the Neurodiversity Foundation

Bi Visibility Day matters to NDF because inclusion fails when people are recognised only through the category that seems most obvious to an observer.

That is familiar in neurodiversity work. A person can be told they do not “look autistic,” that successful study means they cannot have ADHD, or that using speech means they cannot need communication support. In each case, an external snapshot is mistaken for the whole person.

The parallel should be used carefully: bisexuality is not a neurotype, and NDF should not explain sexual orientation through neurodivergence. The shared lesson is about respecting self-description and resisting simplistic either/or categories.

For people who are both bi and neurodivergent, inclusive spaces need to work across those identities. A Pride event can still be inaccessible. A neurodiversity community can still reproduce heteronormative or monosexual assumptions. Good inclusion notices both.

The day therefore invites NDF to practise a broader form of visibility: not making people reveal everything, but building environments where, if they do choose to be known, they are believed and welcomed without having to prove that their identity fits someone else's expectations.

That is a practical standard for any NDF space: visibility should widen people's freedom to participate, not narrow them into a new stereotype.
