O Days 2027

O Days brings together three days of music, art and community on Copenhagen’s Refshaleøen peninsula. The 2027 edition takes place from 5 to 7 August at Sønder Hoved, a waterfront site overlooking the harbour. Electronic music, installations and changing participatory activities come together across the open-air site, creating space for encounters and discovery alongside the programme.

Copenhagen city centre is nearby for travelling to the festival, while storage facilities and food options are available on site. There is no camping at the site, so visitors should arrange accommodation in the city. The full line-up for the edition will be announced gradually throughout the year, completing the programme over the coming months.
