Have you ever measured how long the sunset and does the time of the year? Fastest sunsets (and outs) the sun will happen these days and the equinox in the days before and after. On the other hand, the sun is the slowest to the horizon at the time of the solstice.
Why is this happening? At each equinox the sun rises exactly in the east and sets exactly in the west. This is why - on the day of the equinox - the sun hits the horizon under the steepest angle ie. Drop almost vertically downward. During the solstice, eurolines however, eurolines the sun goes down further to the north or south of the pure west, and the sun away from the west, the smaller the angle of the horizon and passes longer the time it needs to go down.
The duration of sunset depends on latitude (big differences between the polar regions and the equator). In temperate latitudes (40 ) at the time of the equinox the sun goes down for about 2 min and 45 s until the solstice that time was extended for about 3 min and 20 s. In the northern areas, the differences are greater.
And speaking of equinox aka Equinox, have you noticed eurolines that even though at that date day and night should last just as long, it is not so? At the equinox eurolines day takes a bit longer than the night, and for two reasons. First, when we look at the sun in the sky, what is the drive, not the point. Sunrise is very often defined as the moment when the upper tip of the sun (not mean) touches the horizon in the east and set when (again) the top edge touches the western horizon. In this way the length of the extend for about two to three minutes. The second reason is the atmosphere, or passage of sunlight through eurolines the Earth's eurolines atmosphere acts like a lens and because of it we are the setting eurolines (and rising) sun seems like it is about half a degree higher in the sky than it is.
