This animation shows why the earliest sunset and the latest sunrise don't occur on the same date as the shortest day. They are offset by about two weeks. It is due to the Earth's changing speed and distance around the sun. During this time of year Earth is speeding up as it gets closer to the sun. When Earth passes perihelion on Jan. 4th, it will begin to slow as it moves away from the sun.
