Problems in solar terms and lunar calendar

In China's calendar, the earth revolves around the sun for one year, and the moon's waning period is January. Yang is the "sun" and Yin is the "lunar calendar", that is, the moon, so the traditional lunar calendar in China is actually a combination of Yin and Yang. The earth rotates 360 degrees around the sun, and the average 24 parts are divided into 24 solar terms, starting from the "beginning of spring" solar term and ending in the "Great Cold" atmosphere. Therefore, the definition of solar terms is based on the earth's movement, and the annual "beginning of spring" is fixed on February 4th or 5th of the Gregorian calendar.

It takes 8766 hours 13 minutes and 48 seconds for the earth to go around the sun once, which is 1 year. The moon's profit and loss period is 708 hours, 44 minutes and 2.8 seconds, or 1 month. The difference between the solar calendar and the lunar calendar lies in the month: a month in the solar calendar is roughly divided by the annual average12; A month in the lunar calendar is represented by a moon's profit and loss cycle. Therefore, the Gregorian calendar sets a leap every four years (1 many days) to supplement the actual number of suns; The lunar calendar stipulates that the lunar month with "festival" and no "qi" is a leap month. The years with lunar leap months are 13 lunar month, 13 festival and 12 qi. There will be two beginning of spring festivals this year. It is called "spring at both ends of the year"

From this point of view, the Gregorian calendar only considers the solar cycle and completely ignores the moon cycle; However, the traditional lunar calendar in China considers both the solar cycle and the moon cycle. Lunar calendar is more scientific than solar calendar.

Kilometers are different from the rules of the lunar calendar and cannot be converted. In fact, the solar terms of the lunar calendar already include the Gregorian calendar, and there is no need to convert them.

"Come on June 2 1 day in the first half of the year and August 23 in the second half of the year" is also inaccurate, and it is roughly the same.
