You'll get a more accurate result if you compute the difference between the two dates in days and divide by the mean length of a calendar year in days over a 400 year span (365.2425): datediff(day,{start-date},{end-date},) / 365.2425. For instance, select datediff(day,'1 Jan 2000' ,'18 April 2014') / 365.2425.
