What is Scotland's nationwide New Year's celebration called?

Scotland's nationwide New Year's celebration is called Hogmanay.

Hogmanay refers to the Scottish celebration of the last day of the old year and the associated New Year festivities. Major events have been held in cities such as Edinburgh, where torchlight processions, concerts, street parties, and fireworks have made the occasion internationally famous.

The word's origin is uncertain. Scholars have proposed connections with Scandinavian, French, Gaelic, and other linguistic traditions, but no single etymology is universally accepted. That uncertainty is one reason explanations of the term should be treated carefully.

Hogmanay includes customs that vary across Scotland. First-footing, in which the first person to enter a home after midnight brings symbolic gifts, is one well-known tradition, but it is not the meaning of the word itself. Singing “Auld Lang Syne” and welcoming the New Year are central features of modern celebrations.
