No, July 16 is correct. Bernard knows that the month has to be July or August, based on Albert saying that Bernard can't know (which rules out the 18th and 19th, which occur in May and June). Since Bernard then says he knows, the day can't be the 14th, and when Albert says he knows, that rules out August, leaving only July 16. June 17 doesn't work since Albert has already ruled out June with his first response. If the month were June, then Albert wouldn't initially know that it wasn't June 18, so he would not know that Bernard didn't know the answer from the start. Tom meekerdb writes:

I get June 17. If Bernard were given 16 as the date he'd be uncertain between May and July and Albert couldn't resolve them.
