If you don't know when it was planted, then just cut the tree down and count the rings. Easy!

And how much time is equal to a ring ? Four seasons ?

I think one human year equals 7 tree years, or something. So if you know when the tree was planted, just multiply by 7!

That's the wrong sort of bark!

Assuming you live in a region with 4 seasons per year, then yeah.

From what I understand (and according to this), the lighter parts of the rings get created when the tree grows rapidly, which typically happens in spring. And the darker parts get created during slower growth, which typically happens in summer. In autumn and winter, trees tend to not grow.
