Javascript calendar

I’ve recevied new project called DEMS. Purpose of this project, users can send mails, reports and share files through their local area network. In part of this project, users need to type create date in their files like 02/09/2008. So, I have created textbox for typing date format. Unfortunately, users complaint that they don’t wanna type like that into textbox. They wanna choose date format by calendar control. That’s why I need to create calendar control by javascript. I found this page:

This site isn’t cool enough. But they can support what I want to have.
