In many cases, the Gregorian calendar is quite accurate. 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, but they are the fundamental basis for setting some 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 or 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 relied on the stars to make the yellow calendar, and we can see the wisdom of the ancients.

All the stars in the sky have their own gods, and they all have different positions, so naturally there will be what we call good luck or bad luck. The ancient stars, their positions and operating rules all involve the method of choosing dates 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 intention of the ancients, who can be said to be very cautious when choosing the auspicious day of the zodiac. Even down to every month, even every day. Generally speaking, there are things we should pay attention to in the yellow calendar, such as what is more suitable for today and what is not suitable for today. There are clear marks on it, and different people face it in different days.

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