bernard knows months and upon understanding that albert doesn’t know, figures it out.
how?
upon finding out albert doesn’t know, bernard can rule out may and june due to uniques (18 and 19).
since he didn’t know at first, but now does, ruling out may and june leaves july and august.
since he now knows, bernard must not have ‘14’ as it’s ambiguous.
that leaves 15, 16, and 17.
since 15 and 17 are both august, but bernard knows the date... they must be eliminated.
that leaves 16th of july
july 16
This type of test question perhaps explains why Singapore is among the top in math scores.
July 16
July 16th
Albert(month) knows Bernard(day) cannot know. This means that Albert knows the month does not contain a unique date thus eliminating May and June. Once Bernard knows May and June are out then the date he knows gives him the answer. Since the date must be unique to July or Aug, the 14th is out. If the 14th is out and Albert now knows the answer that means that his month was July because if the month was August he would still have two choices and couldn’t be sure.
So this tells Bernie that Albert, knowing only the month, has just eliminate all May and June and leaves July and August.
By announcing that he now knows the correct birthday, Bernie is saying that it is obviously NOT July 14 or Aug 14 because if all Bernie had was the day 14, there would be 2 possible choices.
That leaves July 16, Aug 15 and Aug 18.
For Albert to announce that he now knows Cheryls birthday, that tells us the the birthday is July 16.
If it were the 15th or 17th, that would leave Albert without knowing the precise month, since there 2 August possibilitIes.
Therefore, July 16th is the birthdate.
Albert must have either July or Aug to know that Bernard doesn't know right off the bat, which he would if the birthday were either May 19 (the only 19) or June 18 (the only 18).
It cannot be the 14th because Bernard would still have to choose between July 14 and August 14. So Bernard knows it is either July 16, if he was told 16, and similarly he would know it was August 15 or August 16 if he was told 15 or 16.
But Albert still wouldn't know if he were told August, so he must have been told July. And among the three possibilities that Bernard might know only one is in July; July 16.

We aren’t given her race, sexual preference, or handicapped status, so we can’t possibly answer the question.
Don;t feel bad of you did not get the right answer.
Here is something that will cheer you up:

July 16
I don’t know about the rest of you, but as soon as the b!tch made it a math problem, I left.
File that under "sentences that will get a guy killed."
June 18
May 19. Bernard knew the day but not month. The only unique day is the 19th.
February 32nd.
I really suck at math.
After cypherin’ all the naughts I come up with July 14.
