In-game event calendar

Dears,

Mercy has posted a neat list of in-game events with their respective start and end dates. It shows that for TBC/WotLK realms the Love is in the Air event is scheduled to begin on Feb 14th and last 14 days. I am pretty sure though that is had started as for MoP realm - on 9th, 9PM (btw, there is no such hour as 21:00 PM, just a kind reminder :) ).

Is the post out of date or the in-game or the in-game event has been started too early? Same for the rest of the events in the list - are they accurate or just simply out of date? It may be a surprise for someone expecting to see a given event to end on e.g. 28th of Feb, while in fact it will enf on 24th.

Regards
