Hogmanay (Scots: [ˌhɔɡməˈneː];[1] English: /ˌhɒɡməˈneɪ/ HOG-mə-NAY[2]) is the Scots word for the last day of the old year and is synonymous with the celebration of the New Year in the Scottish manner. It is normally followed by further celebration on the morning of New Year’s Day (1 January) or in some cases, 2 January—a Scottish bank holiday.

The origins of Hogmanay are unclear, but it may be derived from Norse and Gaelic observances of the winter solstice. Customs vary throughout Scotland, and usually include gift-giving and visiting the homes of friends and neighbours, with special attention given to the first-foot, the first guest of the new year.
The etymology of the word is obscure. The earliest proposed etymology comes from the 1693 Scotch Presbyterian Eloquence, which held that the term was a corruption of the Ancient Greek: ἁγία μήνη (hagía míne), or “holy month”.[3] The three main modern theories derive it from a French, Norse or Gaelic root.

The word is first recorded in a Latin entry in 1443 in the West Riding of Yorkshire as hagnonayse.[4] The first appearance in English came in 1604 in the records of Elgin, as hagmonay.[5] Subsequent 17th-century spellings include Hagmena (1677),[4] Hogmynae night (1681),[4] and Hagmane (1693) in an entry of the Scotch Presbyterian Eloquence.[3][6]
