On what date did baseball originate in the US?

Answer 1

Whether you were referring to the date Baseball was first conceived or played, it is impossible to give a specific date for either. However, according to Wikipedia.org (see link, below), "The first known unambiguous, American discussion of baseball was published in a 1791 Pittsfield, Massachusetts, town bylaw, which prohibited the playing of the game within 80 yards (70 m) of the town's new meeting house."
