Cheryl has a birthday, and she doesn't want to share it right away. (Otherwise, we have no challenge to solve.)
So she gives her friends Albert and Bernard a list of 10 possible birthday dates: May 15, May 16, May 19, June 17, June 18, July 14, July 16, August 14, August 15 or August 17.
Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively.
We then have a conversation which progresses as below -
Albert: I don't know when Cheryl's birthday is, but I know that Bernard doesn't know too.
Bernard: At first I don't [sic] know when Cheryl's birthday is, but I know now.
Albert: Then I also know when Cheryl's birthday is.
So, it is possible to deduce Cheryl's birthday?
I'm surprised this was not posted here before. Its become fairly popular recently.
Of course, try to solve it without searching on the internet! Not much fun otherwise.

I could tell the answer just by looking at the problem - "Cheryl's Birthday". 
I ain't got no signature.

Yes.

Here's another question:
Cheryl is 21 years older than her son. 6 years from now, she will be 5 times as old as him.
Question: where is the son's father?

Researching into time travel? Actually baby not born yet so probably just unaware.

Someone else told me the same answer once. He made a mistake in his calculation. I guess you did too.

Nah - I just don't like the guy...

I guess the answer you're looking for is "in her"  (She's 20y3m old and the "baby" -9m)

I never got around to getting into the big deal about this - but as now it hit CP, I took a look. Not particularly difficulty (why was there such a (media/internet) fuss if this was the problem?) and yet a pleasant exercise as I rarely have time for these these days.
Presuming I got it right with July 16th, that is . . .

The big fuss was because it was set in a SAT style test for children 5 years younger than intended and all the little dears went home and cried to their over-protective parents who had failed to teach them that it was OK to admit that there are some things you can't do when you're 10 that you will be able to do when you're 15 and responded by attacking the education authorities rather than deal with their own lack of parenting skills.

Well - in this case I understand the fuss - but on a different level.
To put that type of question on the test clearly calls into question the designer of the test. A test should be difficult enough to allow adequate differentiation amongst those taking it - so a test where no one gets 100% is ideal. On the other hand - putting material into a test is an implicit indication that you should know how to answer it. The injection of an unnerving experience into the test (unless it was for some reason testing this unnerving phenomenon) is incompetent if not outright sadistic.
Actually - you bring back a memory of my own in such a matter (and I always did very well on standardized exams): a question on a state-wide exam asked for what cause a certain person was famous. It turns out they were a furniture designer. That question was absolutely without any merit (and possible added so certain person's offspring can pick up an extra 4-pts). It lay completely out of place not only based upon standard curriculum, but beyond the knowledge and interests of all but a select few. But, back to the subject:
Perhaps the outrage of the parents is not incorrect, but merely misplaced - their should really be an inquiry into what motivated inclusion a question of such a nature. My view of psychologists and sociologists is that they'd not have any qualms about screwing with large numbers of children just to see how it affects them.

Well, yeah, except it was simply a clerical error. The papers for the two age groups were prepared together and the question was inadvertently transposed. As usual c**k-up was always far more likely to be the explanation than conspiracy!

I still don't see how to eliminate August 15 or August 17.
At the point Albert says Bernard doesn't know, It eliminates May and June. Bernards revelation that he knows only eliminates any that are the 14th. But his statement can be true for any of the remaining three dates. Bernard, in fact, WOULD know at this point because there is only one month left for each of the remaining numbers that Cheryl could have told him (15, 16, or 17).
Albert's final statement is merely a "hope" that he knows. He is guessing that because one of his months only has one day left that that is the month, but it could in fact be one of the August days, still.
The way to fix this would be to also include July 15 and July 17 in the list of possible dates.
Any comments? Did I miss something?
