It's currently 2012 right now so just subtract 2015 and 2012 and voila! 3 years.
I decided to make a little chart until 2015:
2012-3 years
2013-2 years
2014-1 year
If you want to find out when a certain year is going to come, just subtract the current year from the year that you want to know how many years it will take until that time.
1754 days until January 13 2015.
Moot question. 2015 is already here.

1742 days until Jan 1 2015 (from today Mar 26 2010).
