Who held the MLB belt on…

Your birthday, your wedding day, the day your team moved to town. Pick a date and see who had the belt.

Every day since April 22, 1876 belongs to one of the 10,799 reigns in the MLB belt's history, so any date has an answer: the franchise holding the belt, which reign of theirs it was, when it began, how many defenses it had and when (or whether) it ended. The link in your address bar updates as you pick, so a date can be shared.
