The best part of the winter solstice is that it also marks a transition to longer days. Even though the winter solstice is the shortest day of the year, the change begins slowly after today.

In just a month, our length of day increases by almost 30 minutes, picking up 9 hours 49 minutes and 57 seconds. The sunset also will happen later and later, giving you more sunshine after work. By the end of January, the sunset is around 6 p.m. and by the end of February, almost 6:30 p.m. The sunrise also starts to get earlier at the end of January.
Even though the days get longer, there is a seasonal lag to temperatures. The lowest average temperatures are usually felt in the middle of January.
