As soon as Sun Yi said this, the room was so quiet that a needle could be heard falling on the ground.

The perpetual calendar in the mobile phone, Jia Daoshi has seen it. At that time, he stretched his neck and squinted his eyes to get a glimpse of the Book of Heaven, but Sun Yi generously stuffed his mobile phone to him and let him see enough.

It's a pity that Jia Daoshi can't understand it.

In the perpetual calendar, there is no auspicious and evil luck that Jia Daoshi is familiar with, and in a small box, except for some Chinese characters that lack strokes, the rest are Arabic numerals and English abbreviations that he does not know. Jia Daoshi had no choice but to seriously copy down the size of the month.

Now Sun Yi announced the specific moment of the conjunction of the sun and the moon on that day, and also gave the margin of error before and after, which greatly surprised Daoist Jia.

Geng Xiucai heard that the Great Unification Calendar was really wrong, and he was silent for a moment and sighed:

"I can't complain that if we are blind and the grass and trees are growing today, it turns out that the Son of Heaven has lost his sky, and Yin and Yang are reversed."

Sun Dingliao made up his mind: "The little brother above the court today, I will never give him my life again." Lord Lidel, I beg you to draw a piece of land for me in Machi Village, and when this battle is over, I will go to Jinzhou to pick up my family, and I will farm and spin hemp there. If Li Del Ye is sent, Dingliao should be fully supported. ”

Sun Yi was overjoyed. I didn't think about it for a big month, but I actually let the chief of staff return to his heart.

Now in the coalition army, there is only one person who can fight a big battle and has an overall view, Sun Dingliao, the former deputy general of the Ming Dynasty. But Sun Dingliao's next request made it difficult for Sun Yi.

Sun Dingliao said: "I am willing to ask Lord Lidel to issue a calendar and relieve the people from hanging upside down." ”

The perpetual calendar in the mobile phone cannot be promulgated at all.

At this time, the common people used the imperial calendar, and the main purpose was to inquire about good luck and bad luck. There is no such thing in the calendar!

At this time, officials at all levels used perpetual calendars, and the most important thing was to carve and change arrows according to the length of day and night inside.

The so-called carved leakage to change the arrow is a water leakage timing method commonly used in the Ming Dynasty of China. Every day at dawn change to an arrow with a scale, every day when it is dark to change to another arrow suitable for night length, and when the water leaks to the scale, the drum rings the bell to tell the time. Because the length of day and night varies throughout the year, it is necessary to adjust the use of arrows with different scales in different seasons according to the length of day and night in Nanjing in the imperial calendar and the distance between the local area and Nanjing.

Although the accuracy of the arrow is very low, it tracks the moment of the true sun every day. The time of the perpetual calendar is the clock time, and there is a natural error of plus or minus 15 minutes from the true solar time.

Sun Yi shook his head with a wry smile and said, "You can't give calendars." ”

immediately aroused Geng Xiucai's righteous indignation: "Lord Lidel, can you bear to let the people in the world suffer!?" ”

Dahai couldn't sit still.

Originally, the Book of Heaven and the calendar were the most secret things in China, and Dahai was already very grateful for not avoiding him, an outsider. Dahai is also self-aware and does not ask for details. But there is a correct calendar that is not made public, as Geng Xiucai said, is to let the world collapse.

Dahai asked softly: "Your Majesty, you don't want to give the calendar, but you are afraid of becoming the target of the public?" ”

At this time, the promulgation of the calendar was the exclusive royal privilege, and if anyone dared to issue the calendar without authorization, it was clear that he had broken with the Ming Dynasty, and there was no difference between Nurhachi and Nurhachi as emperor.

Daoist Jia took a step forward, bowed to Sun Yishen, and said loudly: "Zhu Pingwa is willing to bear this matter on one shoulder!" I would like to issue an article condemning Zhu Di for being unkind to the world, and his descendants have lost the favor of God. I would like to declare that the descendants of Emperor Jianwen Hui have assisted the saints, vowed to rebuild the three generations, promulgate a new calendar, suppress demons and evils, and save the people of Li from fire and water. ”

Geng Xiucai and Dahai in the house didn't know Jia Daoshi's background, and even Sun Dingliao knew about it. At that moment, the three of them came over to greet Zhu Pingwa.

Sun Yi was immediately moved.

In order to present the calendar, Daoist Jia gave himself up.

With Dahai, the minister of Manchuria, present, the identity of Jia Daoist Zhu Junshi can no longer be kept secret!

Sun Yi gritted his teeth one by one, that's it!

Calendar! Calendar now!

First the calendar was given in name, and then slowly the actual calendar was established.

And in the name of Zhu Pingwa, the calendar was awarded!

The descendants of their old Zhu family deserve this honor.

At the beginning, it was Zhu Zaiyu, the son of King Zheng, who broke Zhu Yuanzhang's ban regardless of his own safety, and now it is Zhu Pingwa, a descendant of Jianwen, who is desperate to save the people of the world.

Sun Yi first stated that the perpetual calendar in his mobile phone was not auspicious, and Yang Ritian took the lead in saying that it was acceptable. Yang Ritian said: "The Qin Tianjian of the Ming Dynasty made a mistake, and the auspicious and vicious should not be allowed in the promulgated imperial calendar. Although there is no good luck or bad luck in our new calendar, it is at least in line with the number of days. ”

Regarding the error between the clock time and the true solar time in the mobile phone perpetual calendar, Sun Yi vaguely explained that the time here has an error of plus or minus a quarter of an hour, sometimes the error is in front, and sometimes the error is in the back.

Geng Xiucai suggested that the moments in the perpetual calendar could be made public, and the people of the world could be asked to verify and improve together. Everyone agreed that it was a good idea.

So Sun Yi named the new calendar as the "People's Calendar", which means the people's calendar, in order to distinguish it from the "Imperial Calendar".

Once the name is confirmed, the first thing to do is to determine a standard time for the civil calendar.

There are two ways to determine the standard time of the calendar of various dynasties in history, one is to take the place where the Son of Heaven is located as the standard time, and the other is to take the center of the world as the standard time.

To be honest, Sun Yi was very dissatisfied with the standard time of 120 degrees east longitude in later generations.

120 degrees east longitude is located on the east coast, and the closest major cities to this location are Hangzhou and Qingdao.

As a result of the fact that the people in the western region have to have lunch at 2 p.m., their children leave school at 7 p.m., and before dinner is finished, all the prime-time TV programs have ended, and the next day it is dark to take the national unified examination.

This was a hasty decision back then. If you have a single time zone, you should choose a city in the middle, so that people on both sides can talk to each other.

At present, the nominal territory of the coalition army includes the Wolf Mountain River of the "mother-in-law's family" and the Tumut of the "mother's family", and between the two is the Jiuyuan region.

The longitude of the Kuhara region is 110 degrees east longitude. Based on the current 12 hours of a day in the Ming Dynasty, the earth should be divided into 12 time zones, each 30 degrees. In this case, 15 degrees east of the Jiuyuan time zone is the 125th parallel of east longitude, and 15 degrees west is the 95th parallel of east longitude.

The 125th parallel of east longitude is a famous line, the so-called middle line of the East China Sea in a certain island country in later generations. In the south, the largest treasure island and the Diaoyu Island, which are inseparable from the mainland, are located west of this line. In the north, the 125th parallel east longitude cuts off the western side of the Korean Peninsula, including Dandong and Shenyang in this time zone, and passes through Changchun.

The 95th parallel of east longitude basically passes through Dunhuang. Jiuquan, Jiayuguan and Guazhou are all east of the 95th parallel east longitude, and the nearest big cities to the west are Hami and Lhasa.

Passing through the middle line of Jiuyuan, the 110th parallel east longitude, from north to south are Lake Baikal, Jiuyuan, Yulin, the Yellow River, Jinshan Grand Canyon, Huashan, Huaihua, Guilin, and Zhanjiang. It can be said to be a natural boundary between things and things.

When Jiuyuan and Guilin are the first moments, the 125th parallel east longitude is the last moment, and the 95th parallel east longitude is the first moment.

Sun Dingliao proposed that the middle pile of the three piles of soil in the ancient city of Jiuyuan in the Qin Dynasty be used as the timing center point of Jiuyuan. Everyone unanimously agreed, and decided to go to the ancient city tomorrow on the first day of June to worship heaven and earth.

The crowd was in a state of excitement. Dahai asked if he could go to the ancient city of Jiuyuan tomorrow to worship heaven and earth, whether Manchukuo could adopt the civil calendar in the future, and the time difference between Shenyang City, the capital of Manchukuo, and Alechu City, the capital of Wanyan Jin Kingdom (that is, Acheng near Harbin in later generations), and Jiuyuan.

Sun Yi replied, everyone who goes to Jiuyuan to worship is the same heaven and earth, as long as the physical condition allows, Dahai can of course go. Since the civil calendar is a civil calendar, anyone can use it without approval, and Manchukuo is welcome to work together to improve the civil calendar.

When Dahai learned that the time difference between Shenyang and Jiuyuan was less than half an hour, and the time difference between Alechu City and Jiuyuan was more than half an hour, Dahai's expression was a little strange.

After that, several scholars were in charge of the specific preparation of the civil calendar.

After comparing the perpetual calendar, it is found that until next year, there is no situation where the conjunction of the sun and the moon occurs near the sub-hour, so there is no difference between the large and small months of the civil calendar and the imperial calendar.

However, the solar terms in the perpetual calendar are very different from those of the imperial calendar. The two are the same on the summer solstice and winter solstice, and then the gap between the two solar terms is getting bigger and bigger, and the difference between the spring and autumn equinoxes is two days!

Sun Yi knew that this gap was actually caused by different algorithms. The solar terms of the Ming Dynasty were divided into equal parts of the year, and the perpetual calendar of later generations was the angle of the earth's orbit. This is entirely due to John Tong's advocacy of the Western-style calendar.

In fact, the angle of dividing the time of the year and the angle of dividing the year has its own advantages and disadvantages, but the people of the Qin Tianjian of the Ming Dynasty said that Tang Ruowang could not fight the prediction of the solar eclipse, and the Chongzhen almanac used the algorithm of dividing the angle. It is precisely because of this that after the completion of the Chongzhen calendar, Emperor Chongzhen did not dare to issue a new calendar.

When the Qing Dynasty entered the customs, in order to show its legal status, the Chongzhen Calendar was renamed and immediately issued the "Shixian Calendar" with a deucing angle.

The civil calendar adopts the method of dividing the solar terms, and Sun Yi decided to leave it to everyone for discussion in the future.

Therefore, Sun Yi converted the summer solstice, winter solstice, spring equinox, and autumn equinox in the year of the monkey from this year to the summer solstice, winter solstice, spring equinox, and autumn equinox in the year of the Jiashen Monkey twelve years later, and transcribed them on a piece of paper to prepare for publication.

Jia Daoshi wrote a special article for this purpose, first explaining why the civil calendar should be implemented, then explaining the one hundred and twenty carvings of the Jiuyuan time, once again listing the time difference between the country's big cities and the Jiuyuan time, and finally inviting the people of the world to jointly calculate the civil calendar, calling it "The Correct Theory of the Civil Calendar", and Zhu Pingwa, the descendant of Emperor Jianwen Hui.

Sun Yi's piece of paper, after Geng Xiucai sorted it out, was called the "Twelve-Year-Old Sun Four Elephant Table", as an annex to the "Civil Calendar Theory", please verify.

Sun Yi was inspired to convert the synodic time of the next twelve months, and the moonrise and moonset times on the day of synodism. After Geng Xiucai sorted it out, it was called the "December Taiyin Shuo Lookout Table" as the second annex to the "Orthodox Theory of the Civil Calendar".

After all, there are only four opportunities for verification for two to two minutes a year, and with the "December Taiyin Looktable", the public has 24 more opportunities for verification in the first year.

Dahai specially asked Geng Xiucai to copy a few more copies of the "Orthodox Treatise on the Civil Calendar" for him, saying that he would return to Manchu to pass it on to his colleagues in the museum.

Geng Xiucai copied Dahai while copying: "Brother Dahai is a cheap life, and he starts to be busy when he doesn't take care of rest, but he looks better." ”

Dahai said with a smile: "Isn't it just a cheap life, I drank some gruel in the health team, and I didn't take the medicine, but I felt energetic when I was busy." ”

While they were busy, there were several loud rumblings outside, and Yang Ritian and Sun Dingliao then entered the house with a smile.

"Is it Manchu attacking?" , Zhu Pingwa hurriedly asked.

"No", Sun Dingliao replied, "it was we who blew up the barrage built by the Manchurian soldiers!" ”
