Wat een dag was the Dutch entry in the Eurovision Song Contest 1961 in Cannes, performed by Greetje Kauffeld. The song is sung from the perspective of a young woman experiencing love and generally finding the world to be a lovely place. She sings, for example, that "I have even picked some flowers unpunished/In the park across the street", lending credence to her belief that this is truly her day. The song was performed sixth on the night, following Yugoslavia and preceding Sweden. At the close of voting, it finished in tenth place.
