New Year's Eve

New Year's Eve was a cultural event held on the last day of the year according to some Earth calendars; usually this was 31 December. The events held were often celebrations and parties centred around midnight when the final seconds of the year could be experienced and the beginning of the new year celebrated. (TV: Doctor Who)

By the period of the Second Great and Bountiful Human Empire it was not a well-known holiday, as Sara Kingdom did not recognise it. (TV: The Daleks' Master Plan)
