Hogmanay (pronounced [ˌhɔɡməˈneː]) is the Scots word for the last day of the year and is synonymous with the celebration of the New Year (Gregorian calendar) in the Scottish manner. It is, however, normally only the start of a celebration which lasts through the night until the morning of New Year's Day (1 January) or, in some cases, 2 January which is a Scottish Bank Holiday.
The etymology of the word is obscure. It may have been introduced to Middle Scots through the Auld Alliance. In 1604 the custom was mentioned in the Elgin Records as hagmonay. The most satisfactory explanation is a derivation from the Northern French dialect word hoguinané, or variants such as hoginane, hoginono and hoguinettes, those being derived from 16th century Old French aguillanneuf meaning either a gift given at New Year, a children's cry for such a gift, or New Year's Eve itself. This explanation is supported by a children's tradition, observed up to the 1960s in some parts of Scotland at least, of visiting houses in their locality on New Year's Eve and requesting and receiving small treats such as sweets or fruit. The second element would appear to be l'an neuf i.e. the New Year. Compare those to Norman hoguinané and the obsolete customs in Jersey of crying ma hodgîngnole, and in Guernsey of asking for an oguinane, for a New Year gift.
