I don't know if it makes a difference, but I would take the earliest interview. That way if it does matter, you've done what you can to give yourself the best opportunity.
The purpose of the January interviews is to fill the spots that weren't taken once the 45 days are up after Dec-1st (which would be Jan 15th). Barring the event everyone accepts and the class fills (which I doubt happens for any school), interviewees in January will be selected.
