Atlanta’s 404 Day returns April 4 with Piedmont Park festival, charity run, museum programs and citywide events
A date that doubles as a civic shorthand
Each year on April 4, Atlanta marks “404 Day,” a calendar-date tribute to the city’s original 404 telephone area code. The observance has evolved into a loose, citywide slate of events that blends public celebrations with organized activities tied to community participation and fundraising.
For 2026, multiple organizers have announced programming centered on Saturday, April 4, with major gatherings planned in Midtown and downtown.
Piedmont Park festival scheduled as a free public centerpiece
A free, public 404 Day event is planned for April 4 at Piedmont Park, promoted as a day-long community festival featuring live music, food vendors and neighborhood-focused programming. The event’s organizers have positioned it as an annual celebration of Atlanta culture and a central, daytime convening point for residents and visitors.
Separately listed ticketing for a Piedmont Park 404 Day event indicates an extended schedule into the evening, reflecting how 404 Day celebrations often include both daytime family-friendly activities and nighttime entertainment options.
A new 4.04-mile run adds a fitness and fundraising component
One of the most prominent additions to the 2026 calendar is “The 404 Run,” a 4.04-mile event scheduled for April 4. The run is billed as an inaugural edition designed to reflect the area-code theme while combining running, volunteering and donations. Organizers have indicated the 2026 race has reached capacity, with a waitlist available.
Race-related listings tied to 404 Day also point to coordinated activity at Underground Atlanta, including festival-style programming during daytime hours.
Family programming extends the celebration beyond concerts and parties
404 Day has increasingly appeared across Atlanta institutions as a themed, locally focused day. The Children’s Museum of Atlanta has scheduled 404 Day programming for April 4, presenting the observance as a city-pride celebration tailored to families and younger audiences.
Public-sector recognition has also appeared in local government materials in recent years, reflecting the day’s growing presence as a civic-branded observance rather than a single, centralized event.
