I also thought it had to do with travel. Today a flight can get you anywhere fast. In the early days, horses, carriages, stagecoaches or slow transportation took awhile for you to get to presidential home/white house. Abe Lincoln of Illinois had to get to Washington from Illinois. No cars or planes in those days. He probably took a train. By 1930's transportation had come a long way.Less time for travel, less time to wait so the date was moved to Jan.
