This is why DATE fields were invented (assuming you're using MySQL) - so
that you don't have to maintain three fields, and so that you don't get
problems like this.

It also saves space - a DATE field is 3 bytes, whereas with your scheme
(assuming `year` and `day` are INTs, and `month` is a VARCHAR with
average length of 6.25 characters), then on average that's 15.25 bytes.
P.S. "IE" means Internet Explorer to most people in these newsgroups,
you should use "ie" or "i.e." instead. It took a few minutes to work out
that you weren't talking about IE at all... ;)
