"eve" in this context refers to "the day before". So New Year's Eve is the day before New Year's Day. It is, therefore, the last day of the year that is coming to an end. For people in most Western countries which follow the Gregorian calendar, New Year's Eve is 31 December.
Eve => night before => New years eve => night before the new years day.
The eve, e.g. the night before New Years Day is New Years Eve.
