You can core into the trunk and count rings. The tree won't be harmed.

Ravindrak had it correct except that the question referred to a "live" tree. In order to count the rings you would have to cut the tree down. There are devices which take small diameter core samples without harming the tree. They have a specific name but I can't remember it right now. Also they only work on trees up to a certain diameter.

Core sampling is used on live trees, and the core rings are counted as with cut or dead trees. A core-bore drill is not readily available but perhaps you could borrow one from your forestry department. Be sure to seal the bore-hole.

It is easy to calculate the age of a tree by examining a cross section of the trunk and counting its rings
Each ring is a year old. The number of rings approximates the age of the tree
