311 has officially confirmed the return of their iconic fan event, ‘311 Day’ which will take place on March 7–8, 2026 in Las Vegas — marking the 26th anniversary of the tradition, which alternates between massive Vegas gatherings and themed cruises.
The “311 Day” event was created by the band in 2000 to celebrate their dedicated fanbase on March 11 (3/11). The event has evolved over the years, growing from a single concert into a multi-day festival and community celebration. In 2024, the band held a two-night event in Las Vegas, where they played 86 different songs. In 2025, 311 Day was celebrated with a Caribbean cruise.
311 Day is now evolving into a citywide celebration, featuring immersive fan activations, exclusive exhibits, and special collaborations throughout Las Vegas. The band will perform two completely unique live shows across both nights—with no repeat songs—and will include a special, one-night-only collaboration with the Blue Man Group on select tracks. A pop-up retrospective exhibit will also be featured, showcasing rare artifacts, stage gear, artwork, and poster designs spanning 311’s long history.
