About O Days
O Days returns to Refshaleoen on 5, 6 and 7 August 2027, running three days on the former shipyard land in the east of Copenhagen harbour. The site at Sonder Hoved sits among the industrial buildings that have turned the area into the city’s main cultural quarter, within walking distance of Reffen street food market and a short harbour bus ride from the centre.
The festival describes itself as a meeting of music, art and community rather than a straight concert bill, and splits its work across strands: O/Create for commissioned art and installations on site, and O/FM for the radio and recorded output that continues between editions. That structure places it closer to Copenhagen’s club and art scene than to the Danish festival mainstream.
The 2027 programme had not been published at the time of writing, with the organisers releasing announcements through their mailing list and social channels. A volunteer programme runs alongside the ticket sale. Refshaleoen is reached by the 2A bus or the harbour ferry from Nyhavn, both taking around 20 minutes from the city centre, and Copenhagen itself is the obvious base. It is an urban Danish music festival with an unusually serious art programme.
