Dag Sinterklaasje is a traditional Dutch children's song sung when Sinterklaas departs at the end of his visit in early December. The farewell line is familiar to generations of Dutch schoolchildren, who learn it alongside other Sinterklaas songs for classroom celebrations and the pakjesavond season. Because the tune is simple and instantly recognisable in the Netherlands, short clips of it circulate online every December as festive sound effects, meme audio and video outros, keeping a long-standing seasonal tradition alive in short-form content.
