RE: calculate age based on DoB

Rails

What about this:

def age
Time.now.year - date_of_birth.year - (
((date_of_birth.month * 31 + date_of_birth.day > Time.now.month * 31

  • Time.now.day) and Time.now.year != date_of_birth.year) ? 1 : 0
    ) unless date_of_birth.blank?
    end

That should work I think.

It seems people are now 1 year younger than they actually are. So one
could claim this is the best implementation yet.
