Unpaid, voluntary, community work, often of a practical nature where several people (neighbours, friends, members of an association or union) go together to work. Examples can be spring cleaning in the neighbourhood, construction of a local playground, selling waffles at a sporting event, or helping friends to paint walls in their new apartment. Dugnads are important to Norwegian culture and not participating is heavily frowned upon.
"Blir du med på dugnaden i morgen?"
"Are you coming to the dugnad tomorrow?"
