New word courtesy of Denise Mina and Exile. From wikipedia:

Hogmanay (pronounced [ˌhɔgməˈneː] — with the main stress on the last syllable - hug-m'NAY) 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. Its official date is 31 December (Auld Year's Night). However this is normally only the start of a celebration which lasts through the night until the morning of Ne'erday (1 January) or, in some cases, 2 January which is a Scottish Bank Holiday.
