Longest day in the northern hemisphere.

From a formal point of view, perhaps the longest day will be throughout the summer at the North Pole, because there is a polar day. But if we take the day and the longest day from this point of view, then in the northern hemisphere it will come only on June 22, this is the day of the summer solstice, when the sun rises as high as possible (in each region it is different, but the same is the longest day). Then the day gets shorter.
