MapleStory: Ascension

First time I recall seeing this (the Event calendar). Assuming some other region has it, does it actually work well enough to use? I'm just imaging all the old events that say 2009 somewhere in the data.

KMS has had it since Jump. From the sounds of it, the vast majority of events from this point onwards are going to be these 'attendance check' events, which pretty much require you to log on and do something every day of the event, like killing 200 monsters, for a big reward at the end.
