An old webpage about past doomsday predictions said that Camping predicted the end for 9/6/94, with the second coming on 9/27. Then he predicted it for: 9/29/94, 10/2/94, and 3/31/95. He gave up setting dates afterwards. Again, an OLD web page. He did set dates afterwards...

Well heck, even a stopped clock will get it right sooner or later...
