Why don't the 24 solar terms conform to our traditional lunar calendar?

As early as the Spring and Autumn Period, the 24 solar terms were completely established and became the main basis of agricultural production. The sun runs 360 degrees a year, * * * experiences 24 solar terms, and there are two solar terms every month, which is 24 solar terms a year. It's sunny in beginning of spring, with slight heat in long summer, white dew and cold dew in beginning of autumn, and heavy snow and light snow in beginning of winter 12 solar terms. The second solar term of each month is moderate rain and vernal equinox in Grain Rain, with midsummer solstice and light summer, autumn equinox with early frost, light snow and winter solstice in severe cold.

The twenty-four solar terms correspond to the solar calendar. People refer to these solar terms as twenty-four solar terms, which are fixed in the Gregorian calendar. As a calendar system, it is divided into lunar calendar and solar calendar, which complement each other. Lunar calendar means the moon goes around the earth, and Yin means the moon at night. Calendar is a lunar calendar synthesized after a long journey. In our traditional sense, the lunar calendar is actually a combination of the lunar calendar and the solar calendar. The period of the sun is 365 days and that of the moon is 355 days. Because of the differences between them, there is a leap year every four years.

China's calendar is divided into lunar calendar and solar calendar. We often say that 24 solar terms is divided on the basis of the whole year 12 months, and then every month is divided into solar terms for 30 days, so the previous year 12 months can be divided into 24 solar terms, which is a unique calendar in China. The lunar calendar and the solar calendar are two different calendars, and the 24 solar terms correspond to the solar calendar, that is, the solar calendar.

The twenty-four solar terms are solar calendar, lunar calendar and lunar calendar, which are roughly equivalent to the specific date of each month. The first half of the year is June 6th and 2 1 day, and the second half is August 23rd. Twenty-four solar terms are the characteristics of China calendar, which follow the sun and are part of the solar calendar. The reason why it can't correspond to the lunar calendar is because it has something to do with the solar calendar. The 24 solar terms determine the temperature of the weather, and the position of the sun determines the temperature of the weather, so the solar calendar is the solar calendar and the lunar calendar is the lunar calendar, so the solar terms and the lunar calendar do not correspond.
