I said it during a previous event as well, and some of the comments confirm this. It is -super- confusing to name the 8th as the end-date, when the event ended the very first second of the day. (Even more so cause a large part of the world doesn't use am and pm for times. I never remember if its noon or midnight) It'd cause a lot less confusion and frustration if you'd just say it ends on December 7th at 23.59.59 (or 11.59.59 pm ..)
