Auld Lang Syne is the song traditionally sung at midnight in many countries and is associated with a poem by Robert Burns.
Burns wrote down and adapted the Scottish poem in 1788, drawing on older Scots verses and song traditions. The phrase “auld lang syne” means “old long since,” or more naturally, “for old times’ sake.”
The melody used today became standardized through later musical arrangements and publications. Its New Year association spread internationally, especially through public celebrations and broadcasts.
People often treat it as an exclusively Scottish song, but it is now performed worldwide. The words vary in pronunciation and verse selection, while the familiar refrain remains the central part of the celebration.
