Is this the world’s oldest tweet? Viral X post in Japanese shows impossible 1992 timestamp

Published on March 25, 2026

A recent post Eiko Kano has ignited a wave of curiosity on social media, as it seemingly displays the world’s oldest tweet, dated September 2, 1992. This date predates the founding of Twitter, which was launched in 2006, leading many to question the authenticity of the timestamp.

Kano’s post quickly went viral, attracting attention not only for its perplexing date but also for the nostalgic sentiment it has sparked among users. It coincides with the 20th anniversary of Jack Dorsey’s first official tweet, a milestone that has inspired a flurry of discussions about Twitter’s evolution and the significant moments in its history.

As users began to dissect the peculiar timestamp, some proposed that the post might actually date back to 2011, suggesting that the original creation or posting of the tweet could have been mistakenly attributed to 1992 due to a glitch or formatting error. Nevertheless, the confusion has led to playful “time travel” theories, with some humorously speculating about how someone could have tweeted in 1992, long before the advent of the internet as we know it.

The unexpected resurgence of interest in this tweet has not only highlighted the oddities of social media but has also become a conversation starter about the historical significance of digital communication. Many users are now sharing their own memories of how social media has changed over the years, emphasizing the remarkable journey from early internet culture to the current landscape dominated X, formerly known as Twitter.

As the debate around the authenticity of Kano’s post continues, it serves as a reminder of the quirks of digital timelines and the sometimes mysterious nature of online content, keeping users engaged and entertained in an ever-evolving digital world.
