The 21st century AD.
2015 is the 15th year of the 21st century.
AD 2015 was in the 21st century
The year 100 was the last year of the 1st century AD. As of the 4th of March 2015 that is just over 1914 years and 2 months ago.
2015 is an odd year.
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.
