As to the event and not knowing about it... If your shard has an EM, they have a web site. Get off your lazy butt and check it. Shardname.uoem.net Its really that simple. You also might want to check the Counselor's Hall in northwest Britain, most EMs put out lanterns and such with event days & times - many also put lanterns in Luna.
If you can't or wont check these places you pretty much screw yourself.
