An example of the effect can be seen in sunrise and sunset times around the summer and winter solstice - approximately 21st June and 21st December. Even though the day of the summer solstice has the greatest number of daylight hours it is not the day that the sun rises earliest and sets latest.
The earliest sunrise of the year in the UK occurs about a week before the summer solstice, and the latest sunset about a week after the solstice. In winter the effect is more exaggerated - the earliest sunset occurs about 10 days before the solstice and the latest sunrise about 10 days after the solstice.
This is the time of year when the earth is closest to the sun.

Home Daylight hours. How the tilt of the earth affects daylight Daylight hours throughout the seasons Daylight hours around the world Sunrise and sunset times. It is around After the June solstice, the sun follows a lower and lower path through the sky each day in the Northern Hemisphere until it reaches the point where the length of daylight is about 12 hours and eight to nine minutes in areas that are about 30 degrees north or south of the equator.
Areas 60 degrees north or south of the equator have daylight for about 12 hours and 16 minutes. Earth does not move at a constant speed in its elliptical orbit. Therefore the seasons are not of equal length: the times taken for the sun to move from the March Equinox to the June solstice , to the September equinox, to the December solstice , and back to the March equinox are roughly The consolation in the Northern Hemisphere is that spring and summer last longer than autumn and winter.
Also, Earth is farthest from the Sun, and moving most slowly in its orbit, in early July. This preponderance of longish days gives the Northern Hemisphere more cumulative daylight than the Southern.
BAS , downloadable from SkyandTelescope. Namely, atmospheric refraction allows the Sun to be still visible even when it physically sets below the horizon line. For that reason, average daytime disregarding cloud effects is longest in polar areas, where the apparent Sun spends the most time around the horizon. Places on the Arctic Circle have the longest total annual daytime of hours, while the North Pole receives Because of elliptic nature of the Earth's orbit, the Southern Hemisphere is not symmetrical: Antarctic Circle at hours receives 5 days less of sunshine than its antipodes.
The Equator has the total daytime of hours per year. Further details here on astronomical causes of average daytime variation, and here on Insolation, the solar radiation received at the top of the atmosphere and its effects on the energy received at ground level.
