What is the day of the year when the Great Heat falls? What is the difference between the Great Heat and the Lesser Heat?
The Great Heat solar term falls during the hottest days of the year, which is the period with the most sunshine and the highest temperature, and very little rainfall. So, when does the Great Heat fall every year? In the blink of an eye, we have entered the sixth month of the lunar calendar. What is suitable and unsuitable to do on each day is certainly a concern for everyone. Shuimo.com has prepared a detailed description of each day in June. Let’s take a look.

When is the Great Heat?

Great Heat, one of the 24 solar terms, is the last solar term in summer. Every year between July 22nd and 23rd of the Gregorian calendar, the sun reaches 120° on the lunar calendar, which is the Great Heat solar term. Like Lesser Heat, Greater Heat is also a festival that reflects the degree of heat in summer, and Greater Heat means that the weather is extremely hot. The ancient Chinese divided the Great Heat into three stages: "The first stage is when rotten grass turns into fireflies; the second stage is when the soil becomes moist and the heat is humid; the third stage is when heavy rains come." The Great Heat solar term falls around the middle of the three hottest days of summer, which is the hottest period of the year.

The difference between the Great Heat and the Lesser Heat

1. Different time: The time of Lesser Heat is around July 7 every year (July 6-8).
The Great Heat is around July 23 (July 22-4)
2. The position of the sun is different. During the Lesser Heat period, the sun reaches 105° of the ecliptic longitude. During the Great Heat, the sun reaches 120° of ecliptic longitude.
3. Different climate During the Lesser Heat season, the climate is characterized by rising temperatures and entering the summer drought period. The Great Heat season coincides with the middle stage of the three hottest days of summer, and the climate is characterized by extremely high temperatures.
4. Three different phases The Lesser Heat is divided into three phases: "The first phase is the arrival of warm wind; the second phase is the crickets living in the house; the third phase is the beginning of eagles' prey." The first phase means that after the Lesser Heat, there will be no cool breeze on the earth, but all winds will carry heat waves. The second sign refers to the fact that due to the heat, crickets leave the fields and go to the corners of the courtyard walls to avoid the heat. The third sign is that eagles move around in the cool high altitudes because the ground temperature is too high.
The Great Heat is divided into three stages: "The first stage is that rotten grass turns into fireflies; the second stage is that the soil becomes moist and the heat is humid; the third stage is that heavy rains occur frequently. "The first stage is that fireflies hatch from eggs during the Great Heat. The ancients believed that fireflies turned from rotten grass; the second stage is that the weather begins to become hot and humid, and the third stage is that heavy thunderstorms often occur. These heavy rains reduce the heat and humidity, and the weather begins to transition to the Beginning of Autumn.
