Hi Expert!

Given a DateTime representing a person's birthday, how do I calculate their age?

Thanks in advance.

    Hi Jeet!


    For some reason Jeff's code didn't seem simple enough. To me this seems simpler and easier to understand:

    DateTime today = DateTime.Today;
    int age = today.Year - bday.Year;
    if (bday > today.AddYears(-age)) age--;
