Who invented the lunar calendar? Why is it so accurate to predict the temperature and even the weather of a certain day every year? !

According to legend, a long time ago, there was a young man named Wannian. One day, he went up the mountain to cut wood, because the sun was too hot, so he sat in the shade and rested. Suddenly, the movement of the shadow on the ground inspired him. After returning home, he spent several days and nights designing sundials. But in cloudy, rainy and foggy days, because there is no sun, the measurement will be affected. Later, the dripping spring on the cliff aroused his interest, and he began to make a five-story clepsydra. As time went on, he found that the length of the weather would repeat every 360 days.

At that time, the monarch was called Zu Ti, and the unexpected weather made him very upset. After hearing about it for ten thousand years, I couldn't help but take a sundial and a clepsydra to see the monarch and tell Zu Ti the truth about the movement of the sun and the moon. Zu Ti was very happy after hearing this, and felt very reasonable. So I left for ten thousand years and built the Sun and Moon Pavilion in front of the Temple of Heaven, as well as the sundial platform and the Leaky Pot Pavilion. Zu Ti said to Wannian, "I hope you can accurately calculate the laws of the sun and the moon, calculate the exact time in the morning and evening, and create a calendar to benefit people all over the world. 」

Winter goes and spring comes, year after year. Later, after long-term observation and careful calculation, it took 10 thousand years to calculate the accurate solar calendar. When he showed his successor the solar calendar, he was covered with silver whiskers. The monarch was deeply moved. In order to commemorate the achievements of 10 thousand years, he named the solar calendar "perpetual calendar" and named it the birthday star of the sun, moon and moon.

Today, the calendar at that time was the result of China's long-term observation of astronomical operation in order to master agricultural affairs in ancient times. The lunar calendar in China is called the lunar calendar, because it has not only the elements of the solar calendar, but also the elements of the lunar calendar. It combines the running laws of the sun and the moon and ends their influence on agriculture. Therefore, the lunar calendar in China is more practical and convenient than the pure lunar calendar or solar calendar widely used in the west. Lunar calendar is one of the representatives of China traditional culture, and its accuracy and originality are often regarded as pride by China people.
