Chapter 1525: Calendar (Part 5)

The place where Linglun was located was not particularly remote; on the contrary, it was not far from the city. After descending the mountain, the people from the Sun Observation Group also brought along some of the primary data, and Xuanyuan also ordered people to quickly go find Linglun, as they were about to begin doing something of great importance.

Because Baifeng had stated that the importance of the calendar was extremely high, Xuanyuan once again raised the level of attention given to it, even though it was already sufficiently valued.

For this reason, he felt that they could appropriately slow down the pace of going to the Shennong Clan; the logistics support team had already set off first, and it would not matter if he went a few days late. The main thing was to see this calendar through to completion.

While on the road, Baifeng had already been racking his brains trying to figure out how exactly a leap month should be arranged. In any case, it must be related to the Solar Terms; the problem should lie in the arrangement of the Solar Terms.

If the arrangement of the leap month and the Solar Terms were not proper, then the calendar would likely only be usable for a year or two before it completely lost its accuracy and failed to serve the purpose of guiding agricultural work.

But as for the specifics, he still had to see to what extent Linglun's Lulv Tiaoyang had been accomplished. However, thinking about it, according to the information obtained last year, it should be basically formed by now.

Xuanyuan gathered everyone into an office that had been specifically cleared out. This office could be considered quite spacious and bright; it was built by the Huaxia Construction Team. The current construction level of the Xuanyuan Tribe was unable to build such a large house, and the source of the brightness was also Huaxia's Glass.

The table inside was sufficiently spacious and had been polished with something, making it very smooth. The wood was excellent, so it looked quite good, though it was a bit monotonous.

Sitting on large chairs covered with thick animal hides, everyone gathered together to begin communicating. At this time, even the main officials of the Xuanyuan Tribe, such as Fenghou, Zhishou, Qibo, and Dahong, had all come. Although they did not understand, they also wanted to witness the success of this great event.

Zhishou knew that the Xuanyuan Tribe was observing celestial phenomena, and Kongtong Mountain also possessed knowledge in this area because they had been observing celestial phenomena for a very long time. However, they mostly looked at the stars and did not care how long it took for the moon to wax and wane, or how many years it took for the sun to go from spring to winter. After all, if you could not determine the Summer Solstice and the Winter Solstice, you could not determine the beginning and end of a year, and naturally, there was no way to count how many days were in a year.

His wisdom and knowledge in this regard had not brought any help to Huaxia or the Xuanyuan Tribe, so he did not participate too much in this matter, only believing that this matter was correct and should be done.

Because Baifeng was the one who understood these things best right now, Baifeng took charge and commanded the overall situation, while the others just watched.

Baifeng first asked about Linglun's current progress. According to what Linglun said, in the nearly two years, he had observed this situation many times: the surging of Earth Qi. He had experimented with reed pipes of different lengths and depths. The time interval between each surge of Earth Qi was about fourteen to sixteen days.

He had made records for every instance—the sound, the intensity. Because he knew the pattern, he would lie in wait before the next one appeared. He also discovered that in two years, in the same season, what should have been the same instance of Earth Qi surging would have differences in timing.

Last year it was during the day, this year it might be at night; it would not be the same every time. But because he could not determine which instance they were currently at, nor could he determine how many times it should occur in a year, he could not find the pattern. As for the differences, it was because he compared four consecutive instances over two years and found that they were all at different times, without exception, which was how he reached this conclusion.

Baifeng explained to him, "This phenomenon is related to the operation of Heaven and Earth, but there will be slight differences every year. If there is a difference of a few hours each time, then as the number of times increases, it will naturally appear that one time the interval is fourteen days, another time fifteen days, or even sixteen days."

"However, its total number is fixed; there are twenty-four times in a year. You now look for last year's records and this year's records to see if you can match the Solar Terms of the Summer Solstice and Winter Solstice. You can compare them with the people from the Sun Observation Group."

"Also, Xihe, you people from the Moon Observation Group, compare the days when those stars you mentioned appeared as well."

After Baifeng spoke, they quickly began to move. First, they rummaged through their records. They would record special days, the weather that day, and the weather of the previous few days to determine an approximate date, so that they could make associations. Otherwise, if every day were the same, how could one distinguish which day was which?

The people from the Moon Group said that the data was all in their heads, so they discussed it without paper. In any case, the discussion was exceptionally intense, and the onlookers did not dare to say a word for fear of affecting their train of thought.

"Is it like this?"

"That's it, that's it!! It matches, it all matches!!"

A group of people began to get excited because they discovered that they had basically matched it up. Then Changyi quickly wrote on paper, drew circles, and finally drew something similar to a calendar, but it was not three hundred and sixty-five days; it was from after the Summer Solstice last year until now.

"King of Huaxia! Look, it's like this. On this day, the Summer Solstice! Linglun discovered that there was a surge of Earth Qi on this day, and Xihe also said that from this time on, a star they call the Great Fire was in the south."

"Fifteen days later, Linglun discovered it again. According to how they divided the moon, and then bit by bit like this, when it reached the Winter Solstice, Linglun had another record, and Xihe and the others said that a star called Mao had reached the position in the south."

"Then, reaching this point, counting by three hundred and sixty-five days, today, in another four or five days, there will be another surge of Earth Qi."

Baifeng took the paper and counted it bit by bit. Every important day was marked with a circle. Xuanyuan and the others also stood over and gathered behind Baifeng to watch.

And Baifeng muttered in his mouth: "Summer fills the grain, awn, summer, heat are connected; autumn, limit, dew, autumn, cold, frost... here is Frost Descent..."

Counting to the day representing today, Baifeng pushed forward one more spot, looked up, and suddenly said: "Then in about four days, it will be Grain Rain; Grain Rain is about to arrive."

"What Grain Rain? What is Grain Rain? Is it going to rain millet from the sky?"

The people around asked in a hubbub of voices, while Baifeng judged whether it was correct based on the current climate.

Their current farming in Huaxia relied entirely on experience and human judgment of the temperature, but roughly speaking, the planting of spring wheat was also around the two Solar Terms of Rain Water and Awakening of Insects, because the temperature rose and there was a certain amount of precipitation, which could match the changes in time now.
