Comparison of zodiac signs with the lunar calendar
Almost everyone knows their zodiac sign, but few people know where their zodiac sign is and how it came about?
Stargazing must require some means and methods, such as how to distinguish the position, brightness, names of constellations, etc. of stars. How did the ancients distinguish the stars
How did the stars in the sky record each star? The ancients were very smart. Before the ancient Greek period, in the era of geocentric theory, people believed that the earth did not rotate, but The stars outside were rotating. At that time, it was believed that except for the planets, all the stars were fixed in the stars. The rotation of the stars also had a fixed axis of rotation, which was equivalent to human beings in the ball of stars. , what you see is the inner shell of this star's celestial sphere. So the ancients divided the stars into small piles and small piles, and then gave them names to facilitate recording.
How to divide Western constellations: The position of the stars in the sky is associated with a certain person or animal, and then connected with some myths and stories, so they are divided into small segments, which are called "constellations" .
In his book "Almagest", "Ptolemy" recorded 48 constellations by summarizing previous observations.
After "Hipparchus" and "Ptolemy", later people continued to add and modify, and now there are 88 constellations in astronomy. Among them, there are about 7,000 stars with visual magnitudes above 6 that are visible to the naked eye, and most of them are constant stars in the Milky Way.
Illustration: Position of the Stars by Claudius Ptolemy
The father of azimuthal astronomy "Hipparchus" the ancient Greek, he was the basis of the ancient Babylonians He created a complete trigonometric function and gave the earliest numerical table of trigonometric functions. Therefore, at that time, people thought that the founder of trigonometric functions was "Hipparchus", and he used trigonometric functions to study astronomy. In 134 BC, Hipparchus drew the first starry sky map, the Hipparcos Star Catalog, which included 1,022 stars.
How did he name so many stars?
"Hipparchus" was the first to give the concept of magnitude. He divided all stars into six levels according to their brightness, and the brightest ones were called "1st magnitude stars." The least bright ones that can barely be seen are called "6th magnitude stars". Of course, the magnitude error at this time is still relatively large, because these can only be observed with the naked eye.
Later in 1850, there was a British astronomer named "Pousin". He discovered that the brightness of the 1st magnitude star mentioned by "Hipparchus" was about 100 times that of the 6th magnitude star, so from From this point on, the difference in brightness between each magnitude star (100 to the power 5) is approximately equal to 2.512. That is to say, the 1st magnitude star is 2.512 times brighter than the 2nd magnitude star, and the 2nd magnitude star is brighter than the 3rd magnitude star. 2.512 times, and so on.
With the development of telescopes, some invisible stars can now be seen, and there are also some brighter stars. In fact, their brightness is different, so the apparent magnitude is After being extended, the brighter ones are extended forward, there are "0 magnitude stars" or even negative magnitude stars, and then the darker ones are 7, 8 or even dozens of magnitudes. In short, the smaller the number, the smaller the number. The brighter the star, the larger the number, the darker it is. This is the apparent magnitude. The brightness magnitude of the star itself is called the absolute magnitude, which is the same as luminosity and brightness.
Example:
The first brightest star: Sirius, its apparent magnitude is -1.46, which is the brightest star we can see on the earth except the sun. Star.
The second brightest star: Canopus, its apparent magnitude is -0.72.
What is the visual magnitude of the full moon when we see it from the earth?
Answer: -12.92
What is the apparent magnitude of the Sun during the day?
Answer: -26.74
You will find that it doesn’t seem to be much different. In fact, it is much different. The apparent magnitude of the sun is only about 14 levels higher than that of the moon. , but this is an exponential increase, that is, 14 times 2.512, so the sun is about 400,000 times "brighter" than the moon. The difference in brightness by one magnitude is 2.512 times.
For the naming of a single star, the West usually first states the name of the constellation, then ranks the star according to its brightness in the constellation, and adds a Greek letter (αβγ, etc.), such as "Canis Major" "Alpha" means the brightest star in the constellation Canis Major, which is "Sirius". Zodiac division
The 88 constellations include the "12 constellations". The 12 constellations are also called the "12 zodiac signs". The earth revolves around the sun, and the "zodiac" is the earth's orbit. This is due to the rotation of the earth. The phenomenon observed through rotation is called "diurnal apparent motion", which is equivalent to the fact that in one year, a sun goes around once and returns to the starting point. The ancients called the orbit the sun travels "the ecliptic". The cycle of the sun traveling once is one year. Similarly, the moon will also have a traveling orbit, which is called the "white path", and the cycle of the white path is one month. In fact, these are all phenomena caused by relative motion. The calendar customized through the solar ecliptic is called the "Gregorian calendar", which is a calendar defined by the different positions of the sun. The calendar customized by the moon and the white path is called the "lunar calendar". Almost all the calendars of the ancients were customized by talking about the yellow and white paths, and they considered the yellow and white paths to be very important. The ancient Westerners divided the zodiac almost evenly into 12 parts, each part is a constellation. These are the 12 houses of the zodiac:
Aries,
Taurus,
Gemini,
Cancer,
Leo,
Virgo (Virgo),
Libra,
Scorpio,
Sagittarius (Sagittarius),
Capricorn,
Aquarius (Aquarius),
The sun is almost every month Traveling through a constellation means which constellation the sun corresponds to when it was in the sky on the day you were born, which constellation you are. There are now 13 constellations in the zodiac in astronomy, and an additional "Ophiuchus" has been added, which means that there are now 13 constellations in the zodiac.
Illustration of the divisions corresponding to the dates of "Ophiuchus" fēnHow did ancient Chinese divide the sky?
Answer: It is to use the white path, the trajectory of the moon on the celestial sphere.
The white dào is divided into 4 parts, corresponding to the 4 directions of east, south, west and north. Four kinds of mythical beasts are used to represent the east green dragon, west white tiger, south vermillion bird and north Xuanwu. These four parts are called "four" elephant". Each image is evenly divided into seven sub-segments, and each sub-segment corresponds to the seven planets at that time (metal, wood, water, fire, earth, sun and moon), which are called "Seven Stars". There are seven rays in the sky and five elements on the earth. The four images and seven rays combine to divide the white belt into 28 parts. This is called the "twenty-eight stars". The "twenty-eight stars" are just the stars near the white belt, and the rest are in the north. The half-celestial sphere is further divided into "Three Yuans" (three concentric circles), namely the "Shang Yuan Taiwei Yuan", "Middle Yuan Ziwei Yuan", and "Xia Yuan Tianshi Yuan". Therefore, ancient Chinese people basically divided the sky into "Three Walls" and "Twenty-Eight Constellations".
In fact, our ancients not only studied the white path, but also the ecliptic, but it was not divided into constellations but into "twenty-four solar terms". It is the path of the sun through the sky. A week is a year, and there are four seasons in a year. Therefore, the ancient Chinese were very smart and connected these two things. They used the different positions of the sun in the sky to record the seasons and climate. , this is the "solar term". The General Secretary divides the zodiac into 24 parts, so it is the "twenty-four solar terms". There are 2 solar terms in each month, and the second solar term of each month is called "Zhongqi".
Song of solar terms:
“Spring rain shocks the spring and clears the valley sky, summer is full of awns and summer heat is connected, autumn is dew, autumn is cold and frost falls, winter is snowing and winter is cold.
Note:
The first 6 characters of each sentence represent a solar term. The total of 4 sentences represents twenty-four solar terms. The characteristic of solar terms is that the two solar terms do not change every month, with a difference of one or two days at most. In the first half of the year Coming to the 621st, the second half comes to the 823rd. The last two sentences mean that the solar terms in the first half of the year are generally on the 6th, and the middle energy is on the 21st. The solar terms in the second half of the year are generally on the 8th, and the middle energy is on the 23rd. The difference is only one or two days at most.
The Western constellations and solar terms in our country are all divided into zodiacs. They are essentially the same. For example, Gemini corresponds to the two solar terms of Xiaoman and Mangzhong. The month established by the Baidao and the twenty-four festivals established by the ecliptic constitute our lunar calendar. According to legend, it was established by the ancient emperor. Therefore, it is generally believed that the lunar calendar is the lunar calendar, which is incorrect. The lunar calendar is not a lunar calendar but a lunisolar calendar, because It uses a combination of the ecliptic and the ecliptic. Conclusion
The ancient Chinese were quite good at calendaring. The date subdivisions of the ecliptic, the ecliptic, and the twenty-four solar terms are very accurate. In fact, the current method of studying the starry sky is They are all similar. We also imagine the starry sky as a ball, which is called a "celestial sphere". The only difference is the selection of coordinate systems for different problems. Generally, the celestial sphere is regarded as a ball that is concentric and coaxial with the earth, and the corresponding one is the North Pole. The "North Celestial Pole" and the South Pole correspond to the "South Celestial Pole", and the great circle where the earth's equator intersects with the celestial sphere is called the "celestial equator". The great circle where the earth's orbit intersects with the celestial sphere is called the "ecliptic". The two points where the equator and the ecliptic intersect are the vernal and autumnal equinoxes, which are the symbols of the four seasons.
If we want to study a broader issue, we can say that choosing the sun as the reference system is an illusion of a solar celestial sphere. , the orbit of the sun around the center of the Milky Way, the great circle that intersects with the sun's celestial sphere is the "galactic path" and so on.

12-constellation lunar calendar query
The constellation is determined by the solar calendar date, and the solar calendar date should be used to query the constellation. If a lunar date is used, the corresponding year must be provided so that the lunar date can be converted into a solar date for query. It is impossible to directly use the lunar calendar date to query the zodiac sign. You must convert the lunar calendar date and multiply it by the solar calendar date to query the zodiac sign.
