Lesser Heat is the eleventh solar term of the twenty-four solar terms in the lunar calendar and the fifth solar term in summer, marking the official start of the midsummer season. The Lesser Heat solar term is when the sun reaches 105 degrees of the ecliptic longitude. "Shu" means hot, and "Xiaoshu" means a little hot, not very hot. It means that the weather is starting to get hot, but it has not yet reached its hottest point, and this basically applies to most parts of the country. Crops across the country have entered a stage of vigorous growth and field management needs to be strengthened. When the sun reaches 105° of the ecliptic longitude it is the Lesser Heat.

What is the origin of the Lesser Heat solar term?

The seventh day of the seventh month of the lunar calendar is the day of Lesser Heat. "When the Douzhi Xin signifies Lesser Heat, the weather is already hot but has not yet reached its peak, hence the name." The sun's ecliptic longitude is 105 degrees. The weather is already very hot, but it is not the hottest yet, so it is called Minor Heat.
The Lesser Heat occurs when the sun reaches 105° of the ecliptic longitude on July 7 or 8 every year. "Collected Explanations of the 72 Seasonal Changes" states: "The sixth month... "Heat" means heat, and the heat can be divided into small and large. The beginning of the month is small, and the middle of the month is large. Now the heat is still small." "Heat" means hot. The ancients believed that the period of Lesser Heat was not the hottest time of the year, so it was called Lesser Heat. There is also a folk song about the solar terms that says, "Less Heat isn't that hot, but Greater Heat is the hottest time of the year." It indicates that the hottest period of the year has arrived, but it has not yet reached an extremely hot level. As the saying goes, "The heat is in the dog days." The dog days of summer in my country usually occur 28 days after the summer solstice, which is the so-called "the first dog days of summer solstice".
In ancient my country, the Lesser Heat was divided into three stages: "The first stage is the arrival of warm winds; the second stage is when crickets roost in the house; the third stage is when eagles begin to prey." During the Lesser Heat season, there is no longer a trace of cool breeze on the earth, but all winds carry heat waves; the words describing crickets in "The Book of Songs: July" include "In July, they are in the wild; in August, they are in the house; in September, they are at the door; in October, crickets come under my bed." The August mentioned in the text is the sixth month of the lunar calendar, which is the time of the Lesser Heat solar term. Due to the heat, crickets leave the fields and go to the corners of the courtyard walls to avoid the heat; during this solar term, eagles move around in the cool high sky because the ground temperature is too high.
