The schedule of events is usually posted about 2 weeks before the convention.
Opening and closing times should be posted on our website soon, but in general, you should expect that the con will open around 9am on Saturday and Sunday, and a little bit later on Friday. Attendees who have pre-registered for a Zenkaikon membership will also be able to pick up their badges on Thursday evening.
As far as closing times, you should likely expect that the con will run until around 1-2am on Friday and Saturday, and end in the late afternoon on Sunday.
I hope this helps a bit! Keep an eye on the Zenkaikon website for official opening and closing times very soon.
