Fjord Day (Fjordens Dag) is observed in Denmark every second Sunday of September, celebrating the natural beauty and ecological significance of fjords. The event was initiated by employees of Skibhusgården, a nature and outdoor center in Odense, to promote understanding of this unique natural phenomenon and the importance of preserving fjords and their biosphere. The city of Odense, located near a 13 km long fjord of the same name, celebrated its first Fjord Day in 1991. Today, the celebration includes the Odense and Kerteminde fjords and involves over 150 organizations, associations, schools, and companies. Fjords, characterized as long, narrow inlets with steep sides, attract tourists from around the world due to their breathtaking beauty.
