“Auld Lang Syne” is the traditional New Year's Eve song performed at midnight in many English-speaking countries.
The title uses Scots words that mean roughly “old long since” or “for old times' sake.” The song's familiar lyrics are based on a poem published by Scottish poet Robert Burns in 1788, though Burns drew on older Scots verses and melodies.
People commonly sing it while linking arms or holding hands, especially as the year changes. The lyrics look back on old friendships and shared memories, making the song suitable for a farewell to the old year.
The tune and performance customs vary. It is strongly associated with New Year's celebrations in countries including the United States, Canada, the United Kingdom, Australia, and New Zealand, but it is also known and performed internationally.
