When does it start to get dark in spring?

Before the vernal equinox 18: 00, the days are shorter and the nights are longer in the northern hemisphere, so the sunrise is later than 6: 00, the sunset is earlier than 18:00, and the days are longer and the nights are shorter in the southern hemisphere, so the sunrise is earlier than 6: 00 and the sunset is later than 18:00. The day and night on the equator are equal, and the sunrise is at 6.

At the vernal equinox, the direct point of the sun is on the equator, and the seasons in the northern and southern hemispheres are opposite. The northern hemisphere is the vernal equinox and the southern hemisphere is the autumnal equinox. Since then, the direct point of the sun has continued to move northward, so the vernal equinox is also called the rising equinox. At the vernal equinox, theoretically, the world is as long as day and night (see the dawn). After the vernal equinox, the days in the northern hemisphere are long and the nights are short, while the days in the southern hemisphere are short and the nights are long. In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rain in most inland areas of China, where everything germinates and the climate is changeable. Spring, also called spring, is the first season of the four seasons, which refers to the period from beginning of spring to long summer, and it is the season when everything recovers. In the northern hemisphere, the Gregorian calendar is from March to May, while in the southern hemisphere (such as Australia), it is from late September to late February. The solar terms in spring include beginning of spring, Rain, Sting, Equinox, Qingming and Grain Rain.
