First of all... you'll probably still want to transfer onto Balmung. Roleplay on the other realms is very hit-and-miss, and although there are scattered communities on other US data centre worlds, I don't think I've ever seen one based in an EU realm. Therefore, despite being a US server, Balmung is still your best bet for finding other EU roleplayers, because it has the highest concentration of roleplayers in general. You will almost certainly need to pay a transfer fee in order to get characters onto the realm, but you can bring a full load of 8 with 1 transfer fee. Think of it like the roleplay DLC for the game.
That now cleared up, this tumblr is great:

because they post a list every week of EU-friendly RP events listed on the calendar this week. There's usually at least one on most days, sometimes barring reset days.
My personal favourites to attend are Matron's Reach open hours on Mondays and EU Fight Club on Thursdays.
Attending these can help you build your contacts list of people who will be around at similar times to you!
