Happy Birthday Sherlock!

A little late, I fear, to wish our hero “A Happy Birthday” (we celebrated the occasion on Tuesday evening last (another memorable night) but this post helps to explain why the 6th January has become the recognized date for the Master’s birth (even though there is no real canonical authority for it). Margaret Sterrett (who shares her birthday with Sherlock!) asked me on the night why it’s the 6th, and for the life of me, I couldn’t remember the details.
