Eblog Calendar is a module for Elxis CMS that displays a calendar with links to eblog daily posts and to archive. Daily posts introduced in Elxis 2009.1, so if you use the module on a previous Elxis version it will display the calendar but the links will not work as that version of eblog wont be able to support this feature.
Displays a calendar for the current and the 2 previous (optional) months. If there are eblog posts for a calendar day then that day is specially marked and the module will also display a link to that day posts. Eblog Calendar module uses CSS to control its appearance that is loaded dynamically. If you wish to change the ways it looks just edit this file:
The module has many parameters to control its appearance and has multilingual XML parameters (translated into English, German, Greek, Italian, Spanish, and French).
