"February 4, 2024 at 16:26:53, Sunday, the twenty-fifth day of the lunar month, the beginning of spring. ”
Seeing this information, everyone invariably thought of being a year older and thinking of their birthday.
Birthdays are precious.
A birthday is the day of a person's birth and is a sign of the beginning of life. This day is to be celebrated and commemorated, as it represents the power and wonder of life. Everyone cherishes their birthday and celebrates and commemorates this special day with all their hearts.
Birthdays are precious.
The eight characters of birth refer to the date of a person's birth, and the so-called eight characters refer to eight characters, which are the year stem branch, the month stem branch, the day stem branch, and the time stem branch, these eight words. The eight characters of birth occupy an important position in folk beliefs.
Each birthday is a coordinate point of time and space in the universe, that is, a specific and precise position in the universe at a certain point in time. At the moment when this precise "point" is generated, the sun, moon, water, gold, fire, wood, and earth all have a corresponding relationship with this "point" on the earth. The birth date is a unique life information code for each person, which is precious.
Unfortunately, many people's birthdays are recorded and arranged incorrectly for a variety of reasons!
The calendar we currently use includes the Gregorian calendar, the lunar calendar, and the Ganzhi calendar, in which the information of the Ganzhi calendar is compiled by the Chinese Academy of Sciences. For example, on February 2, 2024 in the Gregorian calendar, the Ganzhi calendar is the year of the Lunar New Year, the second month of the second month, the twenty-third day of the lunar month, and the twenty-third year of the northern month. The time and branch need to be converted again, and there is a time difference in different places, and mistakes are inevitable if you are not careful.
The Ganzhi calendar, which is now recognized as equivalent to the astronomical calendar, has set up astronomical officials to observe celestial phenomena in the Shang and Zhou dynasties or even earlier, and has accumulated astronomical observation data for many years, so it is completely possible to establish a certain connection between certain characteristics of the planets and "time", that is, the year, month, day, and hour. The characteristics of these planets include the orientation observed on Earth, the angles, the interrelationship of the five planets with other planets when they appeared on Earth, and even some kind of orbital position that can be calculated in depth.
The astronomical calendar is an astronomical method of measuring time. By observing the position and movement of celestial bodies such as the sun, moon, and stars, a system of describing and calculating time has been established, and the calculation of solar terms can be accurate to the second. China News Network once reported that Zhang Yang, director of the Science Popularization Department of the Purple Mountain Observatory of the Chinese Academy of Sciences, said in an interview with ** that this precise time is the result of calculations by the Calendar Department of the Purple Mountain Observatory of the Chinese Academy of Sciences. Moreover, the exact time of the 24 solar terms every year will be calculated one or two years in advance and published in the "China Astronomical Almanac" published by the Observatory.
For us ordinary people, how to query, record, and convert our birth date is correct?
First of all, we must understand the fact that the current AD calendar is a calendar that artificially adjusts the time, and the month, day, hour, and second are all artificially adjusted. For example, according to the current International Standard Time, 1 minute = 60 seconds in most cases, and 1 minute ≠ 60 seconds in leap seconds. Therefore, the Beijing time we currently use is the same as the international standard time, and there are artificial adjustment factors. It is generally accepted that the year, month, day, and hour of the Ganzhi calendar are determined by the relative positions of celestial bodies, and there is no need to be adjusted artificially, and it is a calendar that completely conforms to the laws of the universe.
To arrange a person's birthdate, two data are required: the geographical coordinates of the place of birth and the Beijing time at the time of birth.
Calculate the local true sun time from the geographical coordinates of the place of birth and Beijing time, and you can arrange the correct birth date.
True solar time, in fact, is astronomical time. 100 years ago, or further era, from the imperial court to the people, there were special timekeepers and timekeepers. Although the timekeeping tools such as sundials, watches, and drip leaks are relatively simple, they record the arrival of each hour every moment, and the hour is divided into minutes, which is enough. Even at night in the countryside, there are watchmen who keep shouting the beginning and end of a certain hour, and the birth date of the newborn is not recorded incorrectly.
In the second year after the outbreak of the Xinhai Revolution (1912), the Chinese calendar at that time was adopted as the national calendar. With the advent and popularization of clocks and watches, the work of recording solar time became history.
On September 27, 1949, after the adoption of the First Plenary Session of the Chinese People's Political Consultative Conference, the newly established People's Republic of China used the Gregorian calendar and the Common Era, which are common to most countries in the international community, as the calendar and year. The "calendar" we currently use includes the Gregorian calendar, the lunar calendar, and the dry calendar, but if you really use the dry calendar, that is, the true solar time, especially the hour, you need to recalculate.
Currently, a calculation formula is "popular":
True solar time = Beijing time + 4 minutes (local longitude 120).
According to the above formula, the true solar time of Urumqi is calculated at 87The time difference between 48 degrees and 120 degrees east longitude is 2 hours and 10 minutes.
Official Weather**, the following information can be found:
On May 2, 2024, Beijing time, Urumqi sunrise time 06:59:35.
3 cities at the same 120 degrees east longitude:
On May 2, 2024, Beijing time, the sunrise time in Qingdao will be 05:04:05.
On May 2, 2024, Beijing time, the sunrise time in Changzhou will be 05:12:08.
On May 2, 2024, Beijing time, the sunrise time in Tainan will be 05:25:03.
The difference between the sunrise time in Urumqi and any of the three cities is not 2 hours and 10 minutes.
Obviously, the calculation formula is wrong! True solar time is not only related to longitude, but also to latitude. The calculation method of not counting latitude has led to the wrong recording and arrangement of many people's birthdays.
The following examples are also illustrative:
Calculation case 1: Same longitude and different latitudes.
Suppose that A and B were born at the same time Beijing time.
Mr. A, born at 10:30:00 Beijing time on February 4, 2024, was born in Hulunbuir City, Inner Mongolia Autonomous Region.
Mr. B, born at 10:30:00 Beijing time on February 4, 2024, was born in Kaohsiung City, Taiwan Province.
If you follow the above "popular" calculation method, the eight characters of the birth date of the two are all:
癸卯年 Yi Chou Yue Wu 戌 Day Ding 巳 time.
After inquiry, the geographical coordinates of Hulunbuir are 119754589,49.252008, Kaohsiung geographical coordinates 120343302,22.65776, the two places are almost in a straight line at 120 degrees east longitude, with a difference of 23 degrees in latitude between north and south. On February 4, the highest temperature in Hulunbuir was -18 and the lowest temperature was -27, and the highest temperature in Kaohsiung was 34 and the lowest temperature was 25. A family member drinks wine to keep warm from the cold, and B relatives and friends drink cold drinks to prevent heat stroke and swim in the sea, can you say that their birthdays are exactly the same? Is the cosmic information encoded the same?
In this way, the eight characters of the birth date lose the uniqueness of the information code, and even lose the credibility.
According to the calculation of astronomical time, the eight characters of the birth date of the two are as follows:
A: In the year of the Emperor, the month of the month of the month of the year of the Emperor, the day of the second month.
Yi Mao: 癸卯年 Yi Chou Yue Wu 戌 Day Ding Si Shi.
If there is a sundial in the two places, you can observe and verify it yourself or entrust a friend to observe and verify that at 10:30:00 Beijing time on February 4, 2024, the sundial shadow of Hulunbuir will not reach the time line, while the sundial shadow of Kaohsiung will have passed the time line. If you don't have time to verify this year, you can use the method described below to verify next year or the year after.
Calculation case 2: different longitude and same latitude.
Jinan, Shandong, geographical coordinates: 117031789,36.704479。
Xining, Qinghai, geographical coordinates: 101762033,36.645199。
May 2, 2024, Jinan, 16:43:50 Beijing time.
May 2, 2024, Xining, 17:54:54 Beijing time.
The verification method is also very simple, this year's May Day holiday, you can observe and record it yourself or entrust a friend, and there are sundials in parks or scenic spots. At 16:43:50 Beijing time on May 2, 2024, the sundial and sunshadow in Jinan are at the beginning of the Shen time scale; At 17:54:54 Beijing time on May 2, 2024, Xining's sundial is at the beginning of the Shen time scale.
The calculation of true solar time is more complicated. As the Purple Mountain Observatory explains: "This is a complex calculation, not only to calculate the speed and angle of the Sun and the Earth, but also to take into account the gravitational effect of other celestial bodies in the entire solar system, not only a few large planets, but even small celestial bodies." In order to calculate the interaction between these celestial bodies, a simple Newtonian gravitational force is no longer sufficient, and a more advanced theory of gravity in physics needs to be introduced. ”
Simple calculation of true solar time requires specialized knowledge. The calculation formula as shown in the figure below (screenshot of the formula part):
In fact, we are already unconsciously using the above calculation method. Astronomers gave formulas and simple procedures for calculations. The applets we usually check the time are calling a computer language JS code, entering Beijing time, latitude and longitude coordinates, and Beijing time is immediately converted to true solar time. As shown in the figure below (screenshot of the source program):
Many rows of eight characters ** are called in the use of such modules, which is convenient and concise, and users are unconsciously experiencing. However, there is a shortcoming, the latitude factor is not fully considered, the year, month, and day stem branch are correct, and the hour stem branch is wrong. If it happens to be a solar term, such as the beginning of spring, the time is wrong, which means that the day, month, and year are all wrong, and the arrangement of the eight characters is completely wrong.
Easily obtaining the correct birth date can absorb the wisdom of the ancients, and the road is simple.
It's a good idea to observe the sundial.
The first step is to write down the date of birth in the Gregorian calendar, such as February 4, 2024 at 10:30:00 Beijing time.
The second step is to compare the calendar table and convert it to the date of the stem branch, such as the year of the year of the year of the year of the month of the month of the month of the year
In the third step, the time can be selected this year, next year, the year after tomorrow, and the year after ......
Note two points: the later observation date can not be selected as the birthday Gregorian calendar date, but the corresponding Gregorian calendar date of the stem branch day, the month, day and earth branch can be the same, and the online perpetual calendar query is very convenient; Born at night, you can observe the sundial during the day, and you need to use the hour hedging method, such as observing the sundial at 21:00 and 09:00, because the time and time are hedged; In the event of solar terms, check the data and correct it again.
The birthday is a treasure, get it correctly and treasure it well.
