Adventcalendar_XH facilitates to display an advent calendar on your site. The little doors can only be opened by visitors up to the current date. The secrets behind the doors are the contents of CMSimple pages, so it's possible to present whatever you like (poetry, images, videos, products etc.)
It requires a UTF-8 encoded CMSimple_XH installation and jQuery4CMSimple. It is released under GPLv3.
Adventcalendar_XH couldn't be tested so far in various environments. It is a so called BETA version. Use with caution!
