On the first day of the month of January, detective Holmes and Dr. Jane were getting some rest by the fireplace at 221B Baker Street. While Jane was
reading the Times, Holmes was puffing on his pipe. Jane suddenly put up a question to Holmes, What is your birth date? To this, Sherlock Holmes said, You make a guess, Jane. I have no idea, replied Jane. I was "Forty" two days ago and next year I will turn forty three! That is impossible! said Jane. But as always, Holmes was right. Can you tell what day of the year Sherlock Holmes celebrates his birthday?
