You can celebrate many events in game... you just need want to do it instead. Dukes can celebrate festivals and holidays, you can events inside guilds and religions.
I offered prizes of 1000, 500 and 100 gold in a RP event... no one replied. People don't want to interecat in some realms and you cannot force them to do it. If they want to be drones, they would be drones and just it.
