Summer solstice day and night!

This is the sunshine map of the earth around the summer solstice.

The meridian of half the earth divides the earth into 12 parts, and a day is 24 hours, so the time difference between every two meridians is 1 hour (because it is half the earth).

For example, at A in the figure (the same at B or C, but not in the southern hemisphere), the day and night at the intersection of the terminator line and the equator are equally divided, each being 12 hour.

But looking at the northern hemisphere, most of the northern hemisphere is in the sun, especially the daytime hemisphere.

In one place, there is a time difference of 1 hour between the terminator line and the equator. That is to say, in a place, the sun rises at 5 am and sets at 7 pm, so in a place, there are 14 hours during the day and only 10 hours at night.

Around the summer solstice, the farther north (the higher the latitude), the longer the day time and the shorter the night time.

In the Arctic Circle, you can find it in the sun 24 hours a day, without night, only during the day.

Because no matter how the earth turns, all the meridians are within the daytime hemisphere. This is an extreme day. Is the solstice in the summer of 2020 an auspicious day for decoration?
