What is the Scottish New Year's Eve song Auld Lang Syne mainly about?

Auld Lang Syne is mainly about remembering old friendships and shared times.

The song asks whether old acquaintances should be forgotten and answers by calling for memories of “old times.” Its words derive largely from a poem by Robert Burns, who sent a version to a Scottish musical collector in 1788. The poem combines Burns's writing with older Scots lines and traditional ideas.

Although it is strongly associated with New Year's Eve, the song has a broader emotional use. Groups sing it at farewells, reunions, graduations, and other transitions. The New Year's connection grew through public celebrations and radio and television broadcasts, making the song familiar far beyond Scotland. It is therefore best understood as a song of remembrance and companionship, not a literal description of a New Year's ritual.
