I don’t need to tell you this, but that’s already been happening. It might surprise some to learn that although this is the “shortest” day of the year, the sunsets have been getting later for about the past two weeks. But that has been offset by the sunrises which have also been getting later. Sunrises continue to get later and later until early January (perihelion), but after today, the difference in sunrise times is no longer at a bigger difference than sunset times.
