The dates are in the range from 14 to 19. The numbers 18 and 19 appear once. If the birthday is on these dates, then Bernard would immediately say the month.

If Cheryl told Alfred she was born in May or June, then the birthday could be May 19th or June 18th. Since Alfred knows for sure that Bernard does not know the answer, it means that we are not talking about May or June. That leaves July or August.

In July and August there are still dates in the range from 15 to 17, and 14 occurs twice. If the birthday were on the 14th, then Bernard, after Alfred’s remark, would still not be able to give an exact answer. So, we are not talking about the 14th. The remaining dates are July 16, August 15 and August 17.

If Cheryl had told Alfred that she was born in August, then after Bernard’s answer, Alfred could not have known the exact date of birth - after all, 2 whole dates fall in August.
So Cheryl was born on July 16th.
