I keep track of the Official LOTRO Schedule maintained by the Community Manager, Cordovan, and edit my own Google Calendar, embedded below, to show the same data in a different way.

Note: unless it says otherwise, all events will start at 10 AM and end at 3 AM (server time/EST).

Below (and in this link) you can see the events planned until the end of the year.

Just click on the +GoogleCalendar button at the bottom right of the Calendar Widget to add my version of the Events Schedule to your Google Calendar. You can even display it on your phone!
