I keep track of the Official LOTRO Schedule maintained by the Community Manager, Cordovan, and edit the Google Calendar you see below to show the same data in a way that’s more agreeable to my eyes.

Here (and in this link) you can see the events planned until the end of the year. There’s only one event “observed” because the date in the Official source for this calendar seems wrong (a Crafting XP event has never lasted near 20 days – so that’ll need correcting).

You can find a pinned link to the official schedule under the LOTRO Official Info tab of this blog.
