Thoroughbred are considered 3 years old on January 1, no matter what day they were born on.The Kentucky Derby has been won by horses that aren't yet 3 calendar years old, but not by a "2yo".
The answer may have been right, but the term "2yo" in the subject line is wrong.
Not sure I understand your postulation (is that really a word?) Mary.
Say I was born on April 1 - which I was, did I just turn 27 on Monday or did I turn 27 on January 1?
