O Days is a three-day festival on Refshaleøen in Copenhagen where music, art, and community come together in one of the city's most atmospheric locations. Founded by ÅBEN, a Danish craft brewery, and co-produced with Live Nation, the festival grew out of a simple mission: bring people together through shared experiences. What started as an intimate gathering has evolved into one of Copenhagen's most anticipated summer events.
The programming leans into electronic and club culture, with past editions featuring headliners like Justice, BICEP, Honey Dijon, Chase & Status, The Blaze, and Underworld. But O Days is more than just music — art installations by emerging designers, local food vendors, and curated craft beers create a festival that feels as much about the spaces between sets as the performances themselves.
The 2026 edition brings Disclosure, Joy Orbison, Nia Archives, Mall Grab, Yaeji, and The Dare to Refshaleøen for three days at the end of July. Inclusive, intimate, and always surprising — O Days is Copenhagen's answer to the boutique festival.
