Nice 
But are you sure it gives ages 1 year below the real age? Seems to work
fine for me.

I apologize! I must have mistyped something when I put it inside my
helper class. Below are two methods, including yours, both work fine.
I find the first method easier to understand. It also make a little more
sense to me to use just the Date class, as we won’t be dealing with time
when it comes to birthdays and age. I don’t know even know what time I
was born.
def age2(dob)
date = Date.today
day_diff = date.day - dob.day
month_diff = date.month - dob.month - (day_diff < 0 ? 1 : 0)
date.year - dob.year - (month_diff < 0 ? 1 : 0)
end
def age(dob)
Time.now.year - dob.year - (((dob.month * 31 + dob.day >
Time.now.month * 31 + Time.now.day) and
Time.now.year != dob.year) ? 1 : 0)
end

This is a little nicer, gives you the option to return somebody’s age at
some given date.
Thanks to Justin F. for this one.
