September 23rd brought a wave of pride and solidarity to Bluesky, as hundreds of users marked Bi Visibility Day with posts celebrating bisexual and biromantic identities. The conversation centered on a simple but powerful message: bi people exist, matter, and deserve recognition every day — not just on the calendar.

"Today is Bi Visibility Day! Bi experiences are sometimes ignored, forgotten or misrepresented, both within the LGBTQIA+ community and the wider world," wrote @philipcbaldwin.bsky.social in one of the trend's most-liked posts. "Bi identities are valid, wonderful and need to be celebrated. BE PROUD. BE VISIBLE. YOU ARE LOVED."

A 26-Year Tradition With Roots in Activism

According to posts circulating on Bluesky, Bi Visibility Day traces back to 1999, when it was first celebrated as "Celebrate Bisexuality Day" during the International Lesbian and Gay Association Conference in South Africa. User @gcnmag.bsky.social noted this historical milestone, while @vchunky.bsky.social added context: "For the past 26 years, Bisexual and Biromantic individuals have celebrated today to fight against erasure and biphobia."

The emphasis on "erasure" appeared repeatedly throughout the conversation. Multiple users highlighted how bisexual identities are often dismissed, questioned, or rendered invisible — even within LGBTQ+ spaces that should be welcoming. This makes the visibility aspect of the day particularly meaningful.

Personal Celebrations and Lighthearted Moments

Beyond the serious messaging, users shared how they personally marked the occasion. @lucyundersnowe.bsky.social wrote about "wearing nick nelson's patented Coming Out Bi shirt to work" — a reference to the popular Netflix series Heartstopper — before making a self-care decision to turn down a stressful freelance gig.

One user, @definitelyjustbob.bsky.social, injected humor into the feed with a classic misunderstanding joke: "Oh, this is so amazing. I didn't even know they had a whole day for us. Business intelligence isn't sexy — I know! — but it's critical to helping complex operations maximize efficiency in a global setting.... What's that? I'm being told I have made a terrible mistake."

And in a perfectly on-brand move, @funkyearthchild.bsky.social admitted to posting their Bi Visibility Day celebration fic nearly two weeks late, joking that "procrastination is a special feature of bisexuality."

Beyond Bisexual: The Bi+ Umbrella

Several posts emphasized that Bi Visibility Day celebrates more than just bisexuality. Organizations and users referenced "bi+" as an umbrella term encompassing pansexual, omnisexual, fluid, and queer identities — anyone attracted to more than one gender.

"Bi+ is an umbrella term that celebrates everyone who is attracted to more than one gender," posted @lancasterpride.org. "Being Bi+ is not a phase. It's real, it's powerful, and it deserves to" — the post appears to have been cut off, but the sentiment was clear.

@eliot-l.social.coop.ap.brid.gy noted that September 23rd also marks Omnisexual Visibility Day, writing: "Happy #OmniVisibilityDay! #Omnisexual is my newest and perhaps most accurate label. But I guess I still also identify as bi and pan."

Why This Day Still Matters

The recurring theme across hundreds of posts was simple: visibility matters because bisexual people still face unique challenges. Users described feeling erased or invalidated in both straight and gay spaces, making days like this crucial for community building and affirmation.

"Happy Bi Visibility Day to all my bi/pan friends. We all deserve a sweet treat and to be celebrated today," wrote @justarealcoollady.bsky.social, capturing the mix of celebration and validation that defined the day's conversation.

Organizations like @lgbtfdn.bsky.social and @lgbtqbar.bsky.social used the occasion to post official messages of support, with the latter writing: "We're so glad you're part of our world — and we're proud to be creating communities where everyone can love freely, authentically, and without judgment."

The trend also saw some creative cross-pollination, with @shipyrds.bsky.social playfully posting "happy lesbian visibility day from my favorite dyke march shirt" alongside the bi celebration — a reminder that LGBTQ+ solidarity often means celebrating each other's moments of visibility.

What makes this online conversation noteworthy isn't just the volume of posts, but the consistent message that after 26 years, Bi Visibility Day remains necessary. The fact that bisexual erasure still requires an annual day of recognition speaks to ongoing challenges within and beyond queer communities. But judging by the warmth, humor, and solidarity flooding Bluesky feeds, the bi+ community isn't going anywhere — and they're making sure everyone knows it.
