What is ‘404 Day?’ And why are Atlantans talking about it?

This story has been updated.

Atlanta’s got codes — or whatever Ludacris said. And nothing embodies Atlanta’s essence quite like 4-0-4, the city’s first area code and the one that became synonymous with the metropolis.

April 4, “404 Day”, (or known colloquially as “fo-oh-fo day”), stands as Atlanta’s unofficial holiday, celebrating the city’s culture, community and enduring influence.

It’s unclear exactly how this holiday took off. Tales trace it back to a spirited gathering at the legendary Clermont Lounge in 2012, while others recollect its inception a few years prior to 2020. Amid the fog of historical debate and claims of ownership, one truth remains clear: 404 Day is here to stay.

In homage to 404 Day, city officials, businesses, sports teams and thousands of Atlantans celebrate the day across social media and with festivities across the city. From park gatherings, concerts and nature hikes to volunteering and star-studded appearances, the city brims with celebrations.

And Georgians — including Jermaine Dupri and U.S. Sen. Raphael Warnock — are loving it.
