Calendar seems to be a very popular requst.. I have used the Agenda plug in as I found the monthview from EZ very hard to use.. In the end I did not manage to make an even calendar of it..

the agenda template appears easily to be the best way to go.
After messing around with it for all of 10 minutes I have the month view looking great. All I need to do is sort out the day view and Im good to go.
