January 3rd is one of my favorite days of the year in astronomy, because it's the day that the northern hemisphere has its latest sunrise of the winter. This morning in Chicago, the sun rose at 7:19 (though it rose behind a thick rainy overcast), just a few seconds later than it rose yesterday. But tomorrow it will rise just a few seconds earlier, then a few more, until by the end of January it'll rise more than a minute earlier each day.
Meanwhile, thanks to the eccentricity of our orbit around the sun, sunsets have gotten later since the first week of December. It's noticeable now; today's sunset at 16:33 is 14 minutes later than the earliest sunset on December 7th. A week from now sunset is at 16:40; a week later, at 16:48.
By January 31st we will see more clearly that the dark days of northern hemisphere winter are ending. Sunrise at 7:04 and sunset at 17:04 gives us 10 full hours of sunlight, 47 minutes more than we'll get today.
So even though the 115th Congress opened today in Washington, with the House Republicans proposing to geld their own ethics watchdog (and why would they want to do that, hmmm?), at least things will literally get more sunny throughout the country every day for the next six months.
