Why does sunrise times move slower than sunset times?

Answer 1

They don't really, when you calculate the values for the entire year. It only SEEMS that way, in the weeks following the winter solstice in the northern hemisphere. Part of that is because the Earth is in an elliptical orbit around the Sun, and reaches its perihelion (the closest point to the Sun) around January 4 each year. On that day, the Earth is moving fastest in its orbit around the Sun.

If you look at the location of the Sun in the sky at the same time every day for a year, you'll see that the Sun appears to make a figure-8 shaped pattern in the sky. This is called the "analemma"; you may have seen it printed on some globes.

Answer 2

Sunrise times change more slowly than sunset times because the tilt of the Earth's axis causes the length of daylight hours to vary more dramatically in the evening than in the morning as the Earth orbits the sun. This means that sunset times can shift more rapidly compared to sunrise times.

Answer 3

I live in Florida, and i swear that the sunset has been getting later and later, its been setting at 9:10 PM lately, but now its gotten a little later.
