My guess is May 19, but I do not have confirmation.

Should I put spoiler space in front of this? Â I guess I should just in case. Â Answer below...
. . . . . . . . . . . . . . . .
July 16th
Albert's first statement implies that the day is not unique on the list or he would know that Bernard knows and he said Bernard doesn't know. Â Therefor we can scratch off May 19 and June 18 because those are unique days. Â We can even go further and say that his certainty about Bernard not knowing means the months of May and June are entirely out.
This tells Bernard that it must be July or August. Â It can't be July 14th or August 14th because then he still would not know but now he does know, so scratch those dates off. Â This leaves just three dates to chose from: July 16, August 15, and August 17.
Finally the fact that Albert now knows after that means that it must be a month that only has one option left of those three or he would still be uncertain. Â So it must be July 16.

Of course I am. Â I'm smart. Â 
Finally my perfect LSAT scores are good for something.
EDIT: So what does Sec 3 mean? Where was this question?

It's a double trick question.
Cheryl is a psycho bitch and is trying to play the 2 guys off of each other, obviously, to see which one she wants to fuck. Bernard knew all along because she whispered "19" into his ear, but he gave a false answer to throw Albert off the trail.
Bernard will have a birthday present for Cheryl on May 19th, and she will thank him by breaking him off a little. Albert will be all, "But I thought your birthday was July 16th.... *sob*" and then go masturbate and cry.
Think, people.

It was on a test in Singapore if memory serves from the article I read. Which made me think we're really getting our asses kicked in education. Yeah, I can't tell you how many birthdays I've had to guess in this fashion. Â Thank jeebus I took all those discrete logic courses so I can ply intricate knowledge from contrived scenarios.
The correct answer is, "If Cheryl wants a fucking present, she can goddamn well be direct and just say outright when her birthday is because I ain't got time for this bullshit." Â In which case, it'll always be the one of those dates which comes soonest after the current time, so she can get her gifts in the shortest order.

I didn't draw enough from "Bernard does not know too"
Maybe its standard testing, but i didn't understand what they meant in the 5m I pondered this one. Is that standard testing language?

QUOTE Albert's first statement implies that the day is not unique on the list... Am I missing something? QUOTE Cheryl tells Albert and Bernard separately the month and the day of her birthday respectively. Respectively: separately or individually and in the order already mentioned
Thus Albert only knows the month. Implying that the month is not unique doesn't help us at all because every month is a repeat.

The fact that Albert is certain that Bernard doesn't know means that he knows it's not a unique day on the list. Which he could only know if it were July or August.

QUOTE Two former college roommates, both logicians, meet at a conference after many years without contact. While catching up, the two eventually get around to discussing their children. The first logician asks the second how many children he has, and what their ages are. The second replies that he has 3 children, but (ever the logician) he will only reveal clues about their ages. The first logician must deduce for himself the ages of the second's children. "First," says the logician, "the product of my children's ages is 36."
"Second, the sum of their ages is the same as our apartment number in college."
"Third, my oldest child has red hair."
Upon hearing the third clue, the first logician replies at once with the ages of his friend's children. What are they? How do you know?
