The Gregorian calendar is quite accurate in many cases. How did the ancients make the Gregorian calendar?

These days in the yellow calendar depend on the sun, moon and stars. Don't underestimate the rotation laws of the sun, moon and stars, they are the fundamental basis for setting certain days. In ancient China, people studied more about observing astronomical phenomena. During the observation, we found some laws of star rotation. This is how the ancients judged good and bad luck. Good or bad luck is of extraordinary significance to some important decisions.

The so-called celestial phenomena rely on divination, and we all say that the weather is right and the people are harmonious. This is also about astronomical phenomena. The so-called heavenly stems and earthly branches is inferred by observing the changes of the stars. There is a certain relationship between human life and the movement of stars. The ancients made the yellow calendar by the stars, which shows the wisdom of the ancients.

The stars in the sky have their own gods and their own positions, and naturally they have what we call good or bad luck. The ancient stars, their positions, and the rules of operation all involve the method of choosing days on the yellow calendar. This is also mixed with five elements, and the yellow calendar is derived from the continuous exploration of the ancients, which is of great significance.

In this respect, we can also see the intentions of the ancients, who can be said to be very careful when choosing the auspicious day of the zodiac. Even down to every month, even every day. Generally, there are things that we should pay attention to in the yellow calendar, such as which are more suitable for today and which are not suitable for today. There is a clear mark on it, and different people have different days to face it.

The Gregorian calendar is still used in our daily life, such as marriage and some related things. The ancients spent a lot of effort and energy to study the Gregorian calendar, and they made some contributions to later generations. For some readers, it is also more attentive.
