We have all had to create calendar pop up and usually the first thing that comes to mind is “Which calendar pop-up application am i going to use?” Well, YUI certainly makes it an easy decision because it looks good and is fairly easy to create. So when the need arose to create a form which had multiple calendar controls in it (15 to be exact), I found my-self in the need of creating a way to build these calendars with-out coding and configuring these fields by hand. So that being said YUICalendar.js was created out of this need.
With YUICalendar.js you can include the file and simply specify a class name to an imput field and instantly produce a pop-up calendar. Check out the project page on Google at http://code.google.com/yuicalendar/ for more details.
Here is a working example: EXAMPLE
