Which gives us: As always, there are 101 ways to achieve this end result, but I rather like the (key, value) expressions myself. Codebrag.

Instantly, I remembered what problems I had with it in the past, like taking care of not only finding the right dates by only day and month, but also, checking for birthdays today, any upcoming birthdays, or even just looking up user's age based on that information. So, to never ever repeat that code again (and to keep the code DRY), I've decided to write a simple gem specifically for this stuff.
And thus the birthday gem was born. Requirements The gem has been tested against Rails 3 (3.0.9) and Rails 2 (2.3.14), and depends on ActiveRecord and ActiveSupport (for inflections), making it a perfect fit for Rails.
