Geoff:
Speaking as an English member of the group, I can be described as being 
in my sixty-sixth year because I **have completed** 65. So if you are x 
years old, you can be described as being in your (x + 1)th year.

It's used probably in reporting usage - in a newspaper for example - 
and formal statements, not in everyday conversation.
