White nights are common in northern latitudes. But it is in St. Petersburg that they seem especially charming. At dusk, old houses, streets and monuments are transformed.

Step 1
White nights - as is clear from the designation, nights in which the sun only slightly sets over the horizon. Evening twilight lasts until morning, and darkness does not descend on the city. The peak of the white nights falls on June 21-22, i.e. summer solstice. During it, the sun is closest to the Northern Hemisphere (where the city-on-Neva is located). Further south, these dates have the shortest nights and longest days. And in St. Petersburg during this period the nights generally "disappear", giving way to twilight. This does not mean that it becomes light, as in the daytime - a book, for example, is still better to read with additional light from a lamp. But you can walk around the city calmly, without fear of dark alleys - there are simply none at this time of the year.
Step 2
Despite the fact that the peak of the white nights falls on the summer solstice, they themselves begin before it and continue for some time after. Of course, the nights begin to shorten after the winter solstice, December 22, but they become bright enough somewhere in May. The period, which is used to call "white nights", begins around June 10th, reaches its climax on the 22nd and then gradually declines. At the end of June, twilight is still long, but already on July 2-3, they thicken to the usual nighttime darkness.
Step 3
The described phenomenon has the same nature as the polar days and nights, which last six months. The closer a point is to the North Pole, the shorter the days in it in winter and longer in summer. The opposite situation is observed in the Southern Hemisphere, where "white nights" come in winter (December), and in summer, on the contrary, it gets dark quickly. For the same reason, at the equator itself, there are always short morning and evening twilight, and there are no "white nights" or "dark days". Therefore, many also notice that the nights there come very abruptly and just as suddenly give way to a clear day.
