The following feeds are available for your convenience on this website. Firefox can interpret rss feeds directly but there are several feed readers (Sometimes called aggregators) available for every operating system. As there are so many we can not recommend a specifc one.
For the icalendar feed you need a calendar application which can use this type of feed (like for example the Lightning plugin for Thunderbird). Copy the link and add it as a remote calender. (Hint: If you use Lightning set the calendar to read only, this gives you a much nicer details view in Thunderbird!)

News feed (RSS)   Contains the news from our website.

      Event feed (ICAL)   Contains all the events from the current semester.
