Are the dates of the twelve zodiac signs based on the Gregorian calendar or the lunar calendar?

The dates of the twelve (sun) constellations can be divided whether according to the Gregorian calendar or the lunar calendar. It’s just that using the Gregorian calendar to divide is more regular and intuitive, but using the lunar calendar to divide is more confusing. To be precise, the dates of the twelve zodiac signs are divided according to the traditional Chinese 24 solar terms. This division method only applies to the sun sign of the twelve zodiac signs. ?

Constellation is a kind of astrology invented by Westerners. Its principle is to use the earth (people) as a reference object, and according to the stars in the solar system (sun, moon, Neptune, Uranus, Venus, Mars , Pluto, Jupiter, Mercury, Saturn and other planets), study and analyze the impact of these movement laws on various aspects of human life, and explain a person's personality and A prediction system of destiny. ?

The constellations originated from the primitive Babylonians on the Mesopotamian plain. They divided the ecliptic plane into 12 areas, called "zodiac signs". The zodiac signs correspond to the twelve The constellation is based on the 12 middle solar terms (spring equinox, Guyu, Xiaoman, summer solstice, great heat, end of heat, autumnal equinox, frost, light snow, The boundaries of the twelve constellations are divided by the time points of winter solstice, great cold, and rain. Starting from the vernal equinox (the vernal equinox is the moment when the sun shines directly on the earth's equator, that is, when the sun reaches 0 degrees of ecliptic longitude), the twelve constellations are arranged in sequence. The order is: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces. Although Western horoscopes and Chinese birth horoscopes are two completely different systems for predicting life and destiny, the division of the twelve zodiac signs by Westerners and the twelve-month order (month) in the birth horoscopes invented by the Chinese ) have striking similarities. Both prediction systems are based on the twenty-four solar terms uniquely created by the Chinese calendar. The twelve months of the Chinese lunar calendar are based on 12 of the twenty-four solar terms. (Beginning of Spring, Jingzhe, Qingming, Beginning of Summer, Ear Grain, Lesser Heat, Beginning of Autumn, White Dew, Cold Dew, Beginning of Winter, Heavy Snow, Lesser Cold) to divide the boundaries of the months, the Beginning of Spring point (the Beginning of Spring is the first of the 24 solar terms in the lunar calendar, and also the first of the year, that is, It is when the sun reaches 315 degrees of longitude) as the starting point. The twelve months are represented by the twelve earthly branches. The order of arrangement is: Yin (first) month, Mao (second) month, Chen (third) month, Si (fourth) ) month, Wu (May), Wei (June), Shen (July), You (August), Xu (September), Hai (October), Zi (winter) month, Chou (twelfth) month . ?

We all know that the sun is the largest star in the solar system, accounting for 99.8% of the mass of all stars in the solar system. It is the source of all light and heat in the solar system. As the saying goes: "Everything depends on the sun to grow." That is It means that life on earth relies on the energy of the sun to survive, which shows the importance of the sun in the solar system. Therefore, the zodiac sign we usually talk about refers to the sun sign. The sun sign is the constellation (region) where the sun passes through the zodiac at the time when a person is born. ?

The sun sign is very important and has the greatest influence on a person’s personality, but in fact there are other planet signs that are also very important to us and cannot be ignored. The moment a person is born and the positions of the ten planets determine that person's character and destiny, not simply the sun sign. In addition to the sun sign, there are moon signs, rising signs, Jupiter, Mars, Mercury, Pluto, Saturn, Uranus, Neptune, Venus, etc. Various planets will appear in different constellations at different times. Astrologers have proven from thousands of years of practice and experience that the position of each planet in the constellation will have different effects on a person's character and destiny. influence. For example: the rising sign is the constellation where the eastern horizon is when a person is born. Its changes depend on the time and place of birth. The rising sign will affect a person to hold a certain idea and think how to behave in order to be accepted by others. Mars represents desire; Saturn represents responsibility; Neptune represents desire; Uranus represents change; Jupiter represents luck; Mercury represents thought; the sun represents personality traits and inner self; Venus represents love and money; the moon represents emotions; Pluto represents potential; and the rising sign represents lifestyle and how others perceive you. ?

Strictly speaking, if you want to know which zodiac sign you belong to, you must first know your date of birth (year, month, day), time (preferably accurate to the hour and minute), and place of birth. These three prerequisites are the longitude and latitude of your birthplace (note: knowing which province, city, county, or district your birthplace is can be converted into the longitude and latitude of your birthplace). Since Westerners usually refer to birth dates according to the solar calendar (Gregorian calendar), most people think that zodiac signs are calculated according to the solar calendar. For us Chinese, there are still two calendars used to record dates, one is the internationally accepted solar calendar, and the other is the lunar calendar (lunar calendar) that has been passed down by our ancestors and is still in use today. There is a gap between the two. There are certain differences in time. In fact, the two calendars are essentially the same and can be converted into each other. Therefore, whether you know the solar calendar or the lunar calendar, as long as the date and time are accurate, you can calculate it completely correctly. Calculate which zodiac sign you belong to.

In terms of sun signs, how are the twelve constellations specifically divided? I believe you will know the answer after reading the following query table of solar calendar dates and solar term divisions of the twelve constellations, as well as the following examples. ?

The "Inquiry Table for Solar Calendar Dates and Solar Terms Division of Sun Constellations" is as follows:

Solar calendar date of constellation (rough) Solar terms (accurate) ?

Cancer: 06 July 21st--July 22nd (summer solstice to great heat)

Leo: July 23rd--August 22nd (great summer to end of summer)

Virgo: August 23rd - September 22nd (summer to autumnal equinox)

Libra: September 23rd - October 22nd (autumnal equinox to frost)

Scorpio: October 23rd --November 22 (Frost ~ Light Snow)

Sagittarius: November 23--December 21 (Light Snow ~ Winter Solstice)

Capricorn: December 22- -January 19th (Winter Solstice ~ Big Cold)

Aquarius: January 20th--February 18th (Big Cold~Rain)

Pisces: February 19th-- March 20 (Rain to Spring Equinox)

Aries: March 21 to April 19 (Spring Equinox to Grain Rain)

Taurus: April 20 to May 20th (Grain Rain~Xiaoman)

Gemini: May 21st-June 20th (Xiaoman~Summer Solstice)?

The solar calendar dates corresponding to the above-mentioned sun signs It should be noted that the range is only a rough division: according to the solar calendar date, this rough division method will lead to an error probability of about 10%. In fact, the accurate division of sun signs is based on the intersection time points of the qi in the twenty-four solar terms. In addition, the longitude and latitude of the place of birth must be considered, that is, the birth (Beijing) time must be converted into the true sun. (astronomy) time to calculate. We usually see in some magazines or websites that the date classification of constellations is inconsistent. Some are one day early, some are one day late, and some are even two days early (or late). Why only make a rough division? Because it is human nature to be afraid of trouble, complexity can easily make people get lost, and simple things are helpful for people to understand and operate, so some people simplify complex problems and use solar calendar dates to divide the twelve constellations. In fact, this division can be accurate to minutes or even seconds. To be more precise, the twelve Zhongqi node moments among the twenty-four solar terms in China are the moments when the sun enters the twelve constellations of the zodiac, which is also the time dividing point for the division of the twelve Western constellations (sun signs). It should be noted that the time when the sun enters the twelfth house (constellation) is different every year. Therefore, people who are born on a certain day of a certain month in the solar calendar may belong to different categories due to different birth years or birth times. sun sign. For example: two people were born at 13:02 on April 20 of the solar calendar. If they were born in 1968, their sun signs would be Taurus. If they were born in 1959, their sun signs would be Aries. This is a birth year. The date and time are the same but the zodiac signs are different due to different years of birth. Another example: Two people were born on April 20, 2000 in the solar calendar. If they were born at 1:29 on this day, their sun signs would be Aries. If they were born at 3:22 on this day, Their sun sign is Taurus, which is a situation where the year and date of birth are the same but the constellations are different due to different birth times. ?

For Capricorn among the twelve sun signs, the time when the sun enters the Capricorn house corresponds to the "Winter Solstice" in the twenty-four solar terms (at this time, the sun is located at 270 degrees of longitude, which occurs every year The festival takes place at some point between December 21st and December 23rd of the Gregorian calendar). In other words, the date when the sun enters Capricorn every year is on one of the three dates of the solar calendar: December 21, December 22, and December 23. This day is called the junction day of Capricorn. In astrology, it is also called the Sun Transition Sign Day, which means that the sun will pass through two constellations on this day. Therefore, the sun will be in the previous constellation for a period of time during the day, and after a certain point in time, it will switch to the next constellation. A zodiac sign. Therefore, a person born on a zodiac crossing day must look at the specific time of birth (hours, minutes, seconds). If he is born before the conversion time point, he belongs to the previous zodiac sign. If he is born after the conversion time point, he belongs to the previous zodiac sign. It belongs to the next constellation. Here are a few examples to illustrate:?

Example (1):

In 2008, the sun began to enter at 20:03:45 on December 21 (Winter Solstice) Capricorn. That is to say: the period starting from 6:44:19 (light snow) on November 22, 2008 in the Gregorian calendar to the "Winter Solstice" belongs to Sagittarius; starting from the "Winter Solstice" to January 1, 2009 in the Gregorian Calendar The period before 6:40:20 on January 20 (the Big Cold) belongs to Capricorn. ?

Example (2):

In 1934, the sun began to enter Capricorn at 20:49:22 on December 22 of the Gregorian calendar (Winter Solstice).

That is to say: the period starting from 7:44 minutes and 20 seconds (light snow) on November 23, 1934 in the Gregorian calendar to the "Winter Solstice" belongs to Sagittarius; starting from the "Winter Solstice" to January 1, 1935 in the Gregorian Calendar The period before July 21st at 7:28:17 (the Big Cold) belongs to Capricorn. ?

Example (3):

In 1939, the sun began to enter Capricorn at 2:5:55 on December 23 of the Gregorian calendar (winter solstice). That is to say: the period starting from 12:58:28 (light snow) on November 23, 1939 in the Gregorian calendar to the "Winter Solstice" belongs to Sagittarius; starting from the "Winter Solstice" to January 1, 1940 in the Gregorian Calendar The period before 12:44:3 on January 21 (the Great Cold) belongs to Capricorn. ?

If your birth date happens to be near the junction day (boundary day) of the zodiac signs, what method should you use to accurately know which sun sign you belong to? Based on personal practical experience, two methods are introduced below for your reference. ?

The first method is: You can check the 24 solar term intersection time comparison table in the "Perpetual Calendar" or "Constellation Intersection Day Inquiry Table", so that you can know when the sun enters the twelve constellations every year To determine the exact time of your birth, first find out which two closest 24 solar terms (Zhong Qi) your birth time is between, and then refer to the above-mentioned "Sun Zodiac Solar Terms Division Table" to determine which sun sign you belong to. Since the dates of the twenty-four solar terms are solar calendar dates, if you only know the lunar calendar date of your birth, you need to convert the lunar calendar date into a solar calendar date before querying. Using this method to query is cumbersome and inefficient. It is easy for errors to occur due to human negligence. In addition, it is also necessary to consider converting the longitude and latitude of the birthplace and the birth clock time into astronomical time (true solar time) for query. For example: your birth time is 20:32 on February 19, 1923 in the Gregorian calendar. Through the "Perpetual Calendar", you can find that your birth time is in the "Great Cold" of the 24th solar term (9:34 on January 21, 1923 in the Gregorian calendar). 45 seconds) and "rain" (23:59:40 on February 19, 1923 in the Gregorian calendar), you can know that your sun sign belongs to Aquarius. ?

The second method is: you can download and install a professional astrology software on your computer or smartphone, or you can directly use the online constellation (or astrolabe) ranking tool on the website to query. . As long as you enter your birth date, time, birth area and other information, you can quickly and accurately know your sun sign. Some software can also automatically generate a zodiac sign, and can also calculate the rising sign, descending sign, and zenith. Information about zodiac signs, nadir signs, moon signs, Mars signs, Venus signs, Saturn signs, Mercury signs, Jupiter signs, Pluto signs, Uranus signs, Neptune signs, etc. If you only know your lunar (lunar) birthday and use astrology software that only supports solar calendar birthdays to check, you need to use a perpetual calendar (or a lunar and solar calendar date conversion tool) to find out your solar calendar birthday first, and then check it. constellation. If you are using software that supports the lunar birthday function for querying zodiac signs, it will automatically convert the lunar calendar date to the solar calendar date, and can even automatically convert the birth clock time and region information you input into precise astronomical time to calculate the zodiac sign. Related information. Also note: If your birth time is in daylight saving time, you need to convert it to standard time, that is, subtract one hour from the daylight saving time when you were born. If you were born at 5 p.m. in daylight saving time, you should actually be born at 4 p.m. Click here to check, otherwise the queried information such as descending sign, moon sign, rising sign, zenith sign, etc. may be wrong. ?For example: A man was born at 13:52 on July 23, 1971 in Jinghe County, Bortala Mongolian Autonomous Prefecture, Xinjiang Uygur Autonomous Region. Use the online ranking tool to find out that his zodiac sign is: Cancer Sun, Cancer Moon, Libra rising, Aries descending, Cancer zenith, Capricorn nadir.
