Look on GSMArena.com - GSM phone reviews, news, opinions, votes, manuals and more... and put the phone's model name in the search box (upper right). That will give you the release date of that model.

As for how long that particular handset has been in use, there's no way to tell. A 2009 phone that's never been out of the box is 6 years old, but has 0 running time on it (and a totally dead battery).
