Excuse me, what is the time of earth day king, and its relationship with four days and seasonal summer?

According to the theory of yin-yang and five elements, spring is full of wood, summer is full of fire, autumn is full of gold, and winter is full of water, except for lack of soil. Therefore, at the end of each season, there are 18 days belonging to the soil, that is, Tuwang Day, also known as Tuwang Day. Each of the five elements takes 72 days, or 360 days.

Three days before the Grain Rain-Changxia Festival, it was spring soil flourishing; Three days before the summer and before the autumn festival, it was the king of the earth; The first three days from the first frost to beginning of winter are autumn soil flourishing; Three days before the great cold, before the Spring Festival, the winter soil was flourishing.

These four days are: beginning of spring, Changchun, beginning of autumn and beginning of winter.

The end of summer is the last month of summer, that is, June of the lunar calendar. It is the same as the term "long summer" in Chinese medicine.

The King's Day in summer should be held in summer. One is to look at the solar calendar and the other is to look at the lunar calendar, so it depends on the calendar.
