Blade has it listed Aug. 10-12, which sounds right. I don't know the exact hours, but it usually starts after lunch on Friday, and is open most of the day Saturday (9-5 or there abouts). I used to live in Lexington so I went to this show twice a year. My advice would be to go Saturday to see the most stuff. A lot of people don't get there on Friday, and a lot seem to leave early on Sunday. Saturday will give you the most time with the most tables open.
