Just a reminder: The season advertises that it'll end on the 21st (Friday), but it's really midnight GMT on that day. So for those of us in negative time zones (such as North America), it'll really end on Thursday night.
I've seen that paragraph before... is there a reason (other than "it's not on UserVoice yet") why it doesn't show the end time in the user's local time zone? If there's no real reason I'll make a UserVoice out of it and see how many people are interested in that.
