Chapter 234 Your shitty talent (asking for monthly tickets)
Li Chunfeng's holy calendar was revised based on Li Xiang's suggestion.

The Holy Calendar respects objective laws, and the Shengyuan calendar adopts the method of a leap year every four years.

A common year has 365 days, and a leap year has 366 days.

However, Li Xiang did not adopt the 28th day of February in the Julian/Gregorian calendar. Instead, he used a special calculation method to add and subtract months, and revised the calendar in a way that was more suitable for Datang babies.

It should be noted that it is not a custom in our country to have twenty-eight or twenty-nine days in February.

In the Julian calendar established by Caesar, January, March, May, July, September, and November totaled 31 days. In order to show mercy, February was reduced by one day, making it 29 days, and a leap year had 30 days.

During the reign of Octavian, August was named "Augustus". Octavian thought that as the great Augustus, he could not be worse than his predecessors, right?

So August was set to have 31 days, but this number of days was not created out of thin air, so what should we do? Of course, we took one day from February... No, we borrowed one day.

As a result, July, August and September all had 31 days, which was not good. So September was changed to 30 days, October to 31 days, November to 30 days, and December to 31 days. In this way, the regularity of alternating long and short months was disrupted, and it was still affected until modern times, 2,000 years later.

The lunar-solar calendar is still used today. In my country's lunar-solar calendar, a month is generally twenty-nine or thirty days.

The first lunar month of the 19th year of Zhenguan had 29 days, and the second lunar month had 30 days, so there were still two days left until the sports meet.

"Xiang'er." Li Shimin looked up and asked, holding the calendar revised by Li Chunfeng, "Why are January, March, April, July, November and December 31 days long, while the other months are 30 days long?"

Li Xiang cleared his throat, and the highlight was about to begin.

"Isn't this arranged according to our family's birthdays?" Li Xiang said solemnly, "You were born on the 1169rd day of the th month of the th year of the Kaihuang reign of the Sui Dynasty, which is the rd day of the st month of the Shengyuan year . Since you were born in the first month of the Sheng calendar, the first month is a long month, with days."

When Li Shimin heard Li Xiang's reason, his eyes lit up.

"Well, that makes sense." Li Shimin nodded.

"Grandma was born on the Gengxin day of February in the first year of Renshou, which was March 1171th in the st year of Shengyuan, so March is designated as a big month." Li Xiang said again.

When he heard that his wife would have a role to play, Li Shimin glanced at Li Xiang with great approval.

Well, you have steps!
As an extremely loving wife, whenever Empress Changsun wrote a poem, Li Xiang would show it off to his ministers, saying, "Look how beautiful my wife's poems are." Now Li Xiang was so thoughtful that he designated the month of his beloved woman's birth as a big month. How could he not be delighted?

"My father was born on the Guichou day of the leap second month of the second year of the Wude era, which was April 1184, 1186, so April is considered a big month." Li Xiang finished speaking, and added, "My mother was born on the Yicho day of the leap tenth month of the fourth year of the Wude era, which was November , , so November is considered a big month."

"Grandpa was born on November 1136th, the first year of Tianhe in the Northern Zhou Dynasty, which is December th in the Holy Calendar , so December is a long month." Li Xiang then added: "Grandma and Grandpa were both born in January, so..."

At this point, Li Xiang the little elephant spread his hands, expressing his helplessness.

In fact, it was not just Empress Taimu and Li Shimin who were married for the same month, he was also unlucky.

"What about you?" Li Shimin accepted this statement. After all, his mother was born in January and he couldn't force her to do that. He couldn't just change her birthday at the last minute, right? That would be unfilial.

Of course, if there is a conflict with Li Yuan, Li Yuan doesn't mind making some changes to Li Yuan.

He raised his eyes and glanced at Li Xiang: "You are my great grandson, how can you not be included in the list?"

"My grandson is quite unlucky. Like my father, I was born in April according to the lunar calendar..." Li Xiang felt like crying when he said this.

If February is arranged into 28 days like in the Western calendar, then Li Xiang was born in May.

But Li Xiang thinks, I used Western habits before I traveled through time, and I use Western habits after I traveled through time, so wasn’t my travel through time in vain?
It must be corrected! Even if it means sacrificing yourself.

"What about July?" Li Shimin asked again.

"Isn't this the month of my aunt's birthday? So I took July, the month of my aunt's birthday, as the big month." Li Xiang smiled brightly.

"Good, good! Good!" Li Shimin said three times in a row: "Your aunt loves you well!"

This is something that will go down in history. Once the Holy Calendar is released, it will be used even if there is a change of dynasty in the future...

"What about this leap year?" Li Shimin said, pointing to October 1216st, which is a leap year in the calendar of next year, .

"Isn't this where my sister's birthday is..." Li Xiang said with a smile.

According to Li Xiang's definition, every four years is a leap year. Starting from the first year of the Shengli calendar, the leap year month is added to October when Pei Xueqing was born. In every leap year, October will have 31 days.

"You..." Li Shimin shook his head with a smile. Of course, he could not find any fault with seeking benefits for his wife.

Li Xiang also had his own selfish motives in arranging this calendar.

Oh, you, Caesar and Octavian, are allowed to give your months thirty-one days, but I am not allowed to do as someone else does?

Octavian, you and your adoptive father Caesar are the Haier brothers, that is, Shuke and Beta.

Every day, we give names to July and August. Who doesn’t know how to do that?
You have shitty talent.

Besides, considering my grandfather’s achievements, doesn’t he deserve it?
Of course, there is also my father, who gave birth to a saintly grandson like me, which can also be considered a kind of merit...

"If that's the case, then it's settled." Li Shimin nodded and said, "I think this holy calendar is very good, very good."

It’s no wonder that Li Shimin praised it. After all, this is the superiority of the holy calendar.

The 24 solar terms, from the Spring Equinox to the Great Cold, each solar term in the sacred calendar is a fixed three days in a fixed month, for example, the Spring Equinox is a fixed February 3rd to 5th, and the Rain Water is a fixed February 18th to 20th...

If it were a lunar-solar calendar, it would be a bit confusing.

It’s not that it’s messy, as scholars can understand it, but the peasants are at a loss.

A certain author has written more than 700,000 words, but some people still don't understand that Kaiyuan Tongbao was created by Li Yuan. Do you expect the ancient farmers, who all received prenatal education, to read such a complicated lunar calendar?
There is a saying that goes, we cannot be separated from the masses.

After obtaining the new holy calendar, Li Shimin immediately sent someone to summon Zhangsun Wuji and others into the palace.

The first thing the ministers did after entering the palace was to observe the holy calendar with Li Shimin.

"This... the solar terms are so accurate..."

Fang Xuanling flipped through the holy calendar in amazement. He flipped through it from 1215 to 1245 and found that the error of the solar terms was no more than three days. One day was always chosen among those three days.

"If we can promote this calendar and supplement it with the Wuyin Yuan calendar, it will definitely benefit the world!" Fang Xuanling said firmly.

Xiao Yu had been watching from the sidelines for a long time. After listening to Fang Xuanling's words, he immediately supported his good student Li Xiang: "This makes sense. Mencius said, 'If you don't violate the farming season, you will have more grain to eat.' If this calendar can be promoted throughout the country, the people will no longer have to worry about not knowing the farming season!"

"Since all of you are so optimistic about the Holy Calendar, I will officially promulgate it at the sports meeting in two days!" Li Shimin said with finality.

In fact, Li Xiang created this holy calendar not only for these reasons, he also had a deeper purpose.

No matter what, we will have to fight against the three desert religions in the future.

However, polytheistic religions like Taoism, if taken alone, are definitely not as competitive as monotheistic religions.

Therefore, religious reform should also be put on the agenda. You can't just conquer a group of believers and then let them believe in religion, right? That's pure nonsense.

If you want them to get rid of their original beliefs, you can only force them to give you a new belief.

Don’t say that religion is backward or something. Even in this modern era of advanced science, it is still impossible to avoid foolish men and women believing in religion. This is something that cannot be eliminated at all.

What's more, during the medieval period of the Tang Dynasty, religion developed even more barbarically.

If you don't occupy this ecological niche, it will naturally be occupied by others.

Like going back to ancient times and talking about atheism, blah blah blah, and saying that religion is backward and is a product of the poor. These people are completely out of touch with the masses and even more out of touch with reality.

The Holy Calendar is just a beginning. First, the status of Laozi, the ancestor of the Tang Dynasty royal family and the founder of Taoism, must be established, and the rest can be discussed later.

The first thing Old Li did after returning to Lizheng Hall was to go to Daji Hall to visit Li Mingda.

Li Mingda was wearing a green Taoist robe and reciting Huangting, which gave him an ethereal and immortal temperament.

"Sizi." Li Shimin sat on the cushion next to Li Mingda.

"Aye." Li Mingda looked up at Li Shimin, then lowered his eyes again.

She was not in a good mood, and she didn't know why, it was simply not a good mood.

"Just now, Xiang'er came to see me." Li Shimin said in a relaxed tone: "Under Xiang'er's guidance, Li Chunfeng revised the Sheng calendar, taking the birthday of Emperor Shengzu as the first year of Shengyuan, setting each year to 365 days, and each month to 30 or 31 days. Among them, there are six long months, which are set according to the birthdays of our family members."

When Li Mingda heard what Lao Li said, he just moved his ears.

Li Shimin continued, "Among them, Xianger takes the birth months of me, your father-in-law, your mother, the crown prince, and the crown princess as the big month."

"Why are there five people?" Li Mingda suddenly asked.

I originally wanted to ask why Li Xiang was not there, but then I thought, this little bastard hasn’t said anything about coming to visit his aunt for so many days, so I won’t ask you.

"Look, your birthday month is also included among them." Li Shimin said with a smile.

Hearing this, Li Mingda's eyes showed a hint of smile, but he quickly hid it and snorted: "Nonsense, I am just a little girl, how can I be worthy of Dayue?"

Although I said that, what I was thinking in my heart was, "The elephant still loves me."

"Xiang'er said that you are his aunt, so you can naturally take the responsibility." Li Shimin said with a smile.

"Well, what about Xiang'er?" Li Mingda asked again. Of course, she noticed that Li Xiang's name was not among those people.

"Xiang'er? Xiang'er and the prince were born in the same month, so they were put together." Li Shimin said with a laugh.

"Hmph." Li Mingda snorted lightly, but still said it was nonsense.

"You." Li Shimin laughed and said, "You are already so old, but you still have a childish temper. Isn't it just that I haven't come to see you for a few days? Why are you so angry? I heard that you have torn up seven copies of the Huangting Sutra. How can you practice in a state like this?"

As soon as he finished speaking, there was a "swish" sound from Li Mingda's hand.

"Well, this is the eighth one." Li Shimin shook his head helplessly.

This petty-minded person is really... not like me at all.

"Look, when Xiang'er was in Dengzhou, didn't he write to me for several days? Didn't I just pretend nothing happened?" Li Shimin tried to persuade Li Mingda.

Li Mingda then asked, "Why did Aye tear up the memorial of Minister Liu?"

Li Shimin:...

Forget it……

Why is this little wool sweater suddenly leaking air?
This statement was heard from Li Xiang before. When they were visiting their uncle and aunt, Su Yi teased Pei Xueqing about what she would do if she gave birth to a daughter. Li Xiang replied that a daughter was like a woolen sweater, warming both the heart and the body.

Li Shimin remembered these words. Yes, our daughter, Li’s, is Little Woolen Sweater.

"You continue to practice, I want to go back!" Old Li said with a glare, "Read early, and go home to eat after you finish reading!"

Although Li Mingda lived in Daji Hall, he still had to eat in Lizheng Hall.

Occasionally, he would go to Wude Hall to have meals with Pei Xueqing and the others.

Speaking of Wude Hall, Li Mingda suddenly thought of Xiao Yourong.

This girl from the Xiao family is very good at dealing with people, and it is surprisingly comfortable to get along with her.

How about...invite her to Dajidian to play in a couple of days?

Well, it’s not impossible!

Without mentioning what Li Mingda was thinking, let's just say that Li Xiang returned to Lizheng Hall, and the first thing he did was to find Pei Xueqing and tell him about what happened in October of the leap year.

Upon hearing this news, the love in Pei Xueqing's eyes almost froze into water.

For the first time in her life, she did not maintain the dignity of a lady in the daytime, but opened her arms and hugged Li Xiang.

"Xiang'er, you are so nice!"

"Hehe." Li Xiang suddenly laughed wickedly and put his head on Pei Xueqing's slender swan neck.

Delicate and warm, this is how he feels.

"The one we talked about before..." Li Xiang asked with a strange smile: "That... that posture?"

"It's all up to you, brother." Pei Xueqing really would not refuse anything to Li Xiang now.

Even if she were asked to fly up to the sky and pick a star right now, she would probably do it.

What is this? This is something that will go down in history...

From now on, whenever someone mentions Shengli, they will naturally think of her, Pei Xueqing.

What makes it different from an ordinary long month is that it is a long month in a leap year, and its specialness is self-evident.

The two of them hugged each other, just like a couple of gods.

Xiao Yourong, who was far away, saw this and kept curling his lips in his heart.

Ah, I'm so angry, why is it not me in His Highness's arms!
