this question makes no sense.
its actually 20 years into the future, to the year 2015
Super Back to the Future II happened in 1993.
October 21, 2015
The next time will be in 2015 (Easter and all the dates related to it will be one week later in 2015 than in 1959).
Sting is expected back to WWE later this year or early in 2015.
Rites of Passage Mentoring the Future - 2015 was released on: USA: 1 January 2015
October 21, 2015 is the exact date.
The cast of In the Future - 2015 includes: Michael Caine as Fred Ballinger
Back to the Future is what's known as "fiction". The world won't end in 2012, but it won't be because a 1980s movie portrayed a fictional version of the year 2015.
2012 but there are later dates in the future that are not on the actual calendar.
New Year's Eve 2015 is the last day of 2015. New Year's Eve is the day before the new year. Just like Easter Sunday 2015 or Christmas Day 2015 etc. are in 2015, New Year's Eve 2015 is also in 2015. It is not the New Year's Eve that is the eve of the start of 2015, which is where a confusion might arise leading to your question.
2015 is an odd year.
