Don't ask how this subject came up, it won't make any sense, but somebody asked me how many major leaguers were born on Feb 29, the extra day added in leap years. I had a database of such things loaded, so here they are:
The most popular birthday in the database? November 18th, held by 67 big leaguers. The least? Why, February 29th, of course, held by the 12 above. The next least popular? November 14th, held by only 23 big leaguers.
