The third battalion rested at the Jingou Fort for half a day, leaving one team of men and horses to hand over to Kong Youxing, and the other two teams were led by Li Guang to Shimenshui on foot.

Sun Yi and Yang Ritian rode fast horses to the Shimen Barrier City ahead of the third battalion.

Because something happened to the stone gate barrier city.

The military division and the chief of staff are up and running!

As soon as Sun Yi and Yang Ritian entered the Shimen Barrier City, they heard Jia Daoshi and Sun Dingliao arguing loudly in the house:

One shouted: "Small! ”

One said, "Great! ”

Outside the house, Geng Xiucai, who was subordinate to the General Staff, was in a hurry.

Seeing Sun Yi and Yang Ritian, Geng Yanshan hurriedly stepped forward: "Go and persuade them." The two of them didn't care about anything

, I have been fighting for a long time. ”

Yang Ritian asked Geng Xiucai: "Why are they arguing?" ”

Geng Xiucai replied: "The military advisor said that the date was the first day of June, and the chief of staff said that the date was May 30. ”

Sun Yi muttered dissatisfiedly: "Isn't this idle and panicked!" ”

When the two entered the house, they saw Daoist Jia shouting at Sun Dingliao with his throat and patting the wild duck feather fan: "May is small! ”

Sun Dingliao glanced at him, and replied helplessly: "May is big!" ”

"Small! Small! Small! It's small! ”

"Big, you say it a hundred times."

When Daoist Jia saw Sun Yi, it seemed that the child who had been bullied outside found his family to complain: "Master, he is talking nonsense five months old!" ”

Sun Dingliao was so angry that he choked, "It's originally May, how did it become nonsense!" ”

Sun Yi was very helpless, "You guys don't care about the war and quarrel over this little thing?" ”

Jia Daoshi, Sun Dingliao, and Yang Ritian replied in unison: "How can this be a trivial matter!" ”

Seeing Geng Xiucai, who came in later, Sun Yi instructed: "Staff Officer Geng, is there a calendar, check whether May is big or May." ”

In the Ming Dynasty, the calendar was also called the calendar day, and the content includes the day on which each solar term will occur, the month of the month, the month of the month, and when to add the leap month, the name of the daily stem branch, the length of the day, the daily auspiciousness, the good fortune and so on.

The Ming Dynasty promulgated the calendar of the following year on the first day of October every year by the Qin Tianjian, and the emperor first rewarded the imperial ministers and foreign clans, and then distributed them uniformly by the local governments. That's why the calendar is also called the imperial calendar.

Geng Xiucai smiled bitterly and said, "Master, if I have a calendar, why are you here?" I...... I have lived in Changsheng Township for a long time, and I don't know how many years have passed. When I went to the island, I knew that those two days were the summer solstice and the Dragon Boat Festival. ”

Sun Yihao asked Yang Ritian again: "Old Yang, do you know whether May is big or small?" ”

Yang Ritian replied: "I listened to Daoist Jia about the big and small months. ”

Sun Yi couldn't help but admire the fairy days of the two, there was no Jiazi in the mountains, and the cold did not know the year.

Sun Yihao slowly mediated for the two parties, and he first asked Sun Dingliao: "Chief of Staff, you said that it is May, but what is the basis?" ”

Sun Dingliao replied: "I'm in Manchukuo, those scholars say so, they should have checked the imperial calendar." ”

Sun Yi repeatedly asked Daoist Jia: "Military advisor, why do you say that May is small?" ”

Daoist Jia replied: "Master, you forgot, it was said in the Book of Heaven!" ”

Sun Yi remembered that there was indeed a time when Daoist Jia asked him about the monthly arrangements for this year. After Sun Yi checked the perpetual calendar in his mobile phone, Daoist Jia respectfully copied it down.

Is the perpetual calendar in your phone accurate?

Sun Yi didn't dare to guarantee it.

He was a programmer himself, and knew that it was very easy to write a calendar program, and that the person who wrote the program certainly did not verify the accuracy of the dates four hundred years ago.

If there is a calendar for this year, this dispute is not a dispute.

Sun Yi suddenly remembered that when he came to the Ming Dynasty on the first day, it was Daoist Jia who personally told him that day was the first day of the year of the monkey and the month of the horse.

This shows that Jia Daoshi should have a calendar.

"Military advisor", Sun Yi asked, "Is there a calendar for this year?" ”

Before Daoist Jia could speak, Yang Ritian interjected: "Yes! The Taoist priest has a copy! I sent someone to buy it for him last winter. ”

Daoist Jia rolled his eyes and declared, "Lost!" Ma San burned the crops and lost them that day! ”

Sun Yi felt that the program was in a loop.

……

At this time, a soldier came to report: a carriage with a white flag came to Shimenmen, claiming that the car was Dr. Dahai of Manchukuo, who went to Kuku and Tun for treatment due to illness.

Sun Yi once left a message for Dahai, welcoming him to be a guest at any time and under any circumstances.

Jia Junshi hurriedly ordered: "Let go!" ”

But how could the carriage pass through the barricades at the stone gates?

The chief of staff revised Jia's order and said, "Send a stretcher to carry Dahai over." ”

The stretcher is also a "little invention" of Sun Yi, consisting of a few branches and a piece of cloth or a piece of skin, which is specially used to treat the wounded on the battlefield.

Two Manchurian servants carried Dahai on stretchers, a soldier of the first battalion carried Dahai's luggage, and the three of them bypassed the obstacle and came to Shimen Barrier City.

The few people who greeted Dahai at the gate of the city did not expect Dahai to be so sick.

Sun Yi hurriedly ordered: "Send the health team first!" ”

Sun Dingliao couldn't hold back and blurted out: "Dahai, is tomorrow May 30, or the first day of June?" ”

Da Haichong on the stretcher smiled at a few people and replied weakly: "The first day of the sixth month." ”

Sun Dingliao couldn't believe his ears, and asked Dahai: "Isn't May a big moon?" ”

Dahai replied: "May is the big month, today is the thirtieth day of May, and tomorrow is the first day of the sixth month." ”

This time, not only Sun Dingliao, but also Sun Yi and Yang Ritian couldn't believe that the coalition forces had been pressing today as May 29th!

Could it be that the days of the coalition forces have been wrong?

Geng Yanshan stepped forward and asked softly, "Brother Dahai, do you have any calendar days to borrow me to check?" ”

Tahai nodded, pointing to his luggage.

Geng Yanshan hurriedly motioned to carry Dahai to the health team.

……

Under the gaze of everyone, Geng Yanshan turned out Dahai's imperial calendar and handed it to Sun Yi.

The cover of the imperial calendar reads: "The Five-Year Great Unification Calendar of Chongzhen of the Ming Dynasty"

Sun Yi turned the first page, and the title page read:

"The Qintian superintendent is allowed to print the Great Unification Calendar and promulgate it to the world. The forger shall be punished according to the law. If anyone can be arrested, the official will give a reward of fifty taels of silver. ”

Sun Yi couldn't help but smack his tongue, this is the strength of the fight against piracy!

Seeing this, Geng Xiucai explained that the Ming Dynasty strictly forbade the people to study the calendar privately and compile the almanac privately.

Sun Yi was puzzled and asked, "No one learns the calendar, who will make the calendar?" ”

Jia Daoshi replied: "If the descendants of the officials of the Qin Heavenly Prison do not learn the calendar and change to other professions, it is a crime to be assigned to the army." ”

Sun Yi couldn't believe it!

The soldiers and craftsmen of the Ming Dynasty were hereditary, how could even astronomers be hereditary?

Sun Yi shook his head and flipped to the fifth month of the imperial calendar.

The imperial calendar reads "May Big".

Sun Yi flipped to the sixth month of the imperial calendar.

The first day of June is marked with the words: "June Big". The day before the first day of June, it was

"May thirty, Ding Weiyue, Bingyin Day."

Sun Yi opened the perpetual calendar on his phone.

The phone displays:

————————

Friday, July 16, 1632. The fifth month of the lunar calendar is small, twenty-nine days, the year of Renshen, the month of Dingwei, and the day of Bingyin.

Location: Baotou City, Inner Mongolia.

Sunrise 05:22:06 Sunset 20:09:17 Midheaven 12:45:54

Moonrise 03:47:55 Moonset 19:53:51 Mid-month 11:51:57

Wake up at 04:49:51 and darken at 20:41:27

————————

Both versions of the calendar are the Bingyin day of Ding Weiyue, but one is the twenty-ninth day of May and the other is the third day of May.

There must be one who is wrong!

The third day of May in the fifth year of Chongzhen

All the modern perpetual calendars that the author found show that May of the fifth year of Chongzhen is a small month, with only 29 days.

However, in the old Manchu file, the following record appeared in the May file of the fifth year of Chongzhen:

"Thirty days, the second naturalized city."

A very simple and clear sentence.

As far as the author can do, I can't find a copy of Chongzhen's five-year imperial calendar for comparison. It can only be speculated with logic:

At that time, it was impossible for Manchuria to have the ability to make its own calendar. Manchuria and the Ming Dynasty were closely linked, and in June, the Manchurian army was mainly recruited with the Ming Dynasty's Datong Town and Xuanfu Town.

From the first day of the fourth month of Huang Taiji from Shenyang, until the third day of May, the first day of June, and the second day of June, the old Manchu files are recorded every day. "May Day" could not have been the person in charge of the record who was in a dizzy moment.
