Is the summer solstice long in days and short in nights? How long is the summer of solstice?

On the summer solstice, the days are long and the nights are short in the northern hemisphere, while the nights are long and the days are short in the southern hemisphere. Because on this day, the direct position of the sun on the ground reaches the northernmost point of the year, almost directly to the Tropic of Cancer (23 26' north latitude), and the daytime in the northern hemisphere reaches the longest. The farther north, the longer the daytime. On this day, the daily length of Mohe in Heilongjiang can reach 17 hours, and that of Beijing is about 15 hours.

Summer solstice was also called "Summer Festival" and "Summer solstice Festival" in ancient times. In the 7th century BC, the shadow of the sun was measured by civil soil gauge, thus the summer solstice was determined. Solstice is the earliest of the 24 solar terms. The annual summer solstice begins on June 2nd1day (or 22nd) and ends on July 7th (or 8th).

The summer solstice is the largest day of the year in the northern hemisphere, and it is also the day when the sun is the highest from the earth. From summer to the future, the position of direct sunlight on the ground gradually moves southward, and the daytime in the northern hemisphere is shortened day by day. There is a folk proverb that "eating noodles on the solstice in summer will shorten the day".

The solstice in summer is in mid-May. Summer is the biggest and most extreme, everything grows and flourishes here to the extreme, and the sun is also the most extreme, so it is the shortest night and the longest day in a year, which is a white night close to the extreme and the most poetic day in a year.
