I missed them too. Thought Sunday is part of the event being weekend and all. The "Events Calendar" didn't help either, you could see a line going from 26 to 30.
Obviously my fault for missing the time but I suspect many others went by the date too, without realizing that the 30th was included for the few hours after midnight only!
Maybe at that point someone can consider a better way to communicate event times, like a count down somewhere in game..
