What constellations did the famous emperors in China have?

Modern scholars have calculated that Qin Shihuang was born in Gregorian calendar 65438+1October 27th, that is, Aquarius. . Ying Zheng, the first emperor of Qin Dynasty, was born on the first day of the first month in the forty-eighth year (259 BC) in Zhao Haoqi, Qin Dynasty. The Biography of Qin Shihuang written by Professor Wang Liqun has already said that Qin Shihuang was born in the first month of the lunar calendar. This is a link to a web page. Historical Records: "Song Zhongyun was born in the first month, so his name is correct." That is, I was born on the first day of the first month. Some scholars put it as 65438+1October 27th. This is the link to the webpage. Below the webpage is the preface/preface of the book. In addition, before the Qin dynasty unified the six countries, the calendar of the Qin dynasty was the same as that of the Xia calendar, with silver moon (1 month) as the first month. So Qin Shihuang was born in January. Yes, if you have any questions, please read the following:

Qin Shihuang unified the six countries and promulgated a unified calendar-Zhuan Xu Calendar. This calendar takes October as the first month of each year, but it is still called "October" if it is not called "the first month"; The fourth month (that is, the first month) is called "Duanyue" because it avoids the name of Qin Shihuang. September is the last month of the year. If there is a leap month, there is a so-called "post-September", and a year ends in the "post-September" accordingly.

Spring and Autumn and Warring States Calendar

There is no complete information about the arrangement method of calendars in the Spring and Autumn Period and the Warring States Period in history. We can only infer the general situation of the calendar in this period from the time of events recorded in historical books such as Spring and Autumn Annals and Zuo Zhuan.

As can be seen from the book Spring and Autumn Annals, there are twelve months in a year in the Spring and Autumn Period. Every month, the day when the sun meets the moon is the first day, called the new moon; The last day is called unlucky. In the middle of the Spring and Autumn Period, the ancients had mastered the relatively accurate length of the first month of the lunar calendar and were able to calculate the roughly accurate first month of the lunar calendar. At the end of the Spring and Autumn Period, 19 calendar and leap week appeared, and the ancient calendar made new progress. The Calendar (a lunar calendar invented by Xin in the Eastern Han Dynasty) stipulates that a tropical year is equal to 365.25 days, a lunar month is equal to 29.53085 days, and seven leap months are inserted in 19 lunar years, so it is called the Calendar. ) is 365.25 days, and the leap is set according to the law of 19 7 years, which means the length of 235 moons and 19 years. From this, we can draw a conclusion that the length of the moon is 29.53085 days, which is much more accurate than that of the previously known A moon, about 29.5 days.

In the early Warring States period, the power of the Zhou emperor declined, and the vassal state was divided into two and no longer obeyed the central government. Even the calendars they use are different. The calendars used in this period include Xia, Yin, Zhou, Lu, Huangdi and Zhuan Xu, which are collectively called the ancient six calendars. Although the names are different, they are all four-season calendars, but some put the beginning of a year in 1 1 month, and some put it in 1 February or1month; Another difference is that the starting point and era of the calendar are also different.

Attachment: at the beginning of the year

The winter solstice is the starting point of the 24 solar terms and the beginning of a tropical year. If the twelve earthly branches are used to mark the month, then the month of the winter solstice should be the second month, the next month of the winter solstice is the ugly month, the next month is silver moon, and so on. At the end of the Spring and Autumn Period, Lu people thought they were descendants of Zhou, so they used the calendar of Zhou Dynasty to put the beginning of the year in the second month, and the descendants were called. Guo Zheng and Guo Song think that the lunar calendar they use is to put the beginning of a year on an ugly month, so they call it Andrew. Jin, Qin and some smaller countries start the year. It is said that the calendar of the Xia Dynasty started with silver moon, so it was called Xia Zheng. The lunar calendar we use now actually started in silver moon, so the lunar calendar is sometimes called the summer calendar. The use of different endings is determined by the habits of various vassal States. Check the calendar and the first year of the year.
