This calendar is based on javascript and php, and it uses mysql to storage the events.
To run it properly you have to modify the calender/config.php file, and set your login data right.
As for now, you must also create a table within your database by executing the SQL statement below:
CREATE TABLE eventcalender (
id INT AUTO_INCREMENT ,
year INT(4) NOT NULL ,
month INT(2) NOT NULL ,
day INT(2) NOT NULL ,
starttime VARCHAR(5) NOT NULL ,
stoptime VARCHAR(5) NOT NULL ,
title VARCHAR(255) NOT NULL ,
description TEXT NOT NULL ,
url VARCHAR(255) NOT NULL ,
PRIMARY KEY (id)) ENGINE = InnoDB;
