Since this is professional, I need also several things:
1: Language support.
2: If I pick Feburary, it doesnt show a legal day as 31
3: 3 dropdown boxes: One for month, another for day and another for year
4: It needs to return a string such as 12-31-2012 which I can easy capture and send it via POST/GET. If can be configured even better
5: Lightweight; No external libraries
