( CNN ) Are you smarter than a really smart Singapore high school student ? See if you can figure out Cheryl 's birthday , the Singapore logic problem that 's got the Internet twisted into knots . Some are even saying it 's the math equivalent of the `` What color is the dress '' debate . The puzzling problem went viral after Singapore television host Kenneth Kong posted it to Facebook . Cheryl 's birthday challenge was meant to test the better high-school students competing in the Singapore and Asian Schools Math Olympiad , held April 8 . Here it is : Cheryl has a birthday , and she does n'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 . A brief conversation between Albert and Bernard -- who we assume are not lying for the sake of this problem -- gives the reader enough clues to eliminate nine of the 10 dates and discover Cheryl 's birthday . That 's assuming you want to celebrate with Cheryl after she 's put you through all that trouble . See our video below for the answer from Georgia Tech Mathematician Matt Baker . The New York Times and the Washington Post have also posted solutions to the problem , along with explanations . Of course , the Internet has offered other solutions .
