Winter officially starts on December 21st this year, and is considered the day with the shortest amount of sunlight. However, the earliest sunset actually occurs before the solstice. How come these don't line up? While the length of a day is defined as 24 hours long, in reality, it varies slightly due to the spin of the Earth. The actual length is defined as a "solar day," and its length can vary from a few seconds to 30 seconds longer than 24 hours. Additionally, latitude plays a role. At our latitude around 40 degrees North , the earliest sunset occurs during the first several days of December, then begins to get later starting around the 14th.

The shortest day of the year might be a couple of weeks away still, but the earliest sunsets are already here. Evenings actually will start getting brighter again Tuesday, according to timeanddate. It's a misalignment of light that few people notice every winter, said Dan Everly, a longtime Ohio astronomer. The sunsets had been creeping earlier each evening until this week when they finally reached p. The sun will continue setting at that time in the state's capital until Tuesday when it comes one minute later at p. On Tuesday, the first day of the later sunset, the sun will come up at a.

It takes more time for the sun to appear to circle the sky once, so this means solar noon—when the sun is due south in the sky—is a little bit later in the day, according to a notional clock keeping an average time. He still assumed those orbits were circular, however. That means our planet moves about one degree per day because there are degrees in a circle. However, during this time, the sunrise steadily gets later, and doesn't reach its latest point until around New Year's Day. The culprit is its orbit—or, more accurately, the shape of its orbit.

This caused by two things, the first is that Earth's orbit is an elipse, not a circle, this means that the angular velocity of earth is not constant. Multiple locations were found.

It was Johannes Kepler, using meticulously curated observations made by his mentor Tycho Brahe, who realized those orbits were, in reality, ellipses—a breakthrough insight that at last allowed astronomers to accurately predict planetary positions and better understand our local cosmic neighborhood.

This translates to a corresponding "relative lateness" of the times of sunrise and setting. This means that the actual length of days in solar time - from noon to noon, measured when the sun appears due South for example with a sundial varies slightly: the nearer the Earth is to the Sun, the bigger the angle it swings through in its orbit relative to the Sun each day, so the further it has to turn so that the same part of it faces the Sun, so the longer the day is.
