If you meaan the calendar on the front page, I think it's just a simple script (php?) that changes the image every day.
Yes it is. It is just a php-script that changes the image and the text-date every day. It is not so VERY hard to make if you know a little php. You can actually make a lot more advanced stuff than that with php 
Yep, PHP. A good place to learn about that is planetsourcecode.com
You basically want a script top read the day, date, etc and use the date to call an image and echo the day and date.
