Years, Months, Days
February 11, 2014
I was watching the Olympic Games this weekend, and one of the commentators remarked that one of the athletes was the youngest ever to accomplish some goal, aged so many years, so many months, and so many days, which was a few days younger than the previous youngest athlete. That didn’t matter so much to me, but it did suggest today’s exercise.

any rule against using standard Date APIs?
Isn’t it more fun to roll your own?
