Traditionally, a grand celebration is held around the arrival of the New Herring. In Scheveningen, close to The Hague, about 200.00 people celebrate the arrival of the new herring and eat it raw.

During Vlaggetjesdag, visitors are invited to watch spectacular demonstrations by rescue teams, participate in old Dutch children's games, admire famous artists, watch the Royal Navy, tour boats and old fire engines, enjoy demonstrations of old crafts, sing along with shanty choirs and enjoy the many colourful traditional costumes.
