Why do zodiac signs and constellations take 12 as the cycle?

12 The reason why the zodiac adopts the period of twelve is because it corresponds to the earthly branch and astronomical calendar in China. The 12 constellation in the west is mainly human-centered and distinguished by the trajectory of the sun.

Speaking of the zodiac, everyone is certainly familiar with it. We know that everyone's zodiac sign is determined from birth and will never change again. The zodiac in our country is also very cute. There are twelve kinds of animals: rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs. As time goes by, the zodiac is not only a symbol of everyone's zodiac, but also an annual mascot. Whenever Chinese New Year is celebrated, Spring Festival couplets and flower arrangements representing this year's zodiac will be posted, which is very interesting and festive.

This is why it is the zodiac. Mainly because China ancient science and technology is not so developed, there is no accurate astronomical instruments. A month's time can only be determined by observing the moon with the naked eye. The wise ancients found that the moon orbits once every 30 days or so, and it happens to be 12 times a year, so a year is divided into 12 months.

The choice of animals is not arbitrary. Careful observation of 12 zodiac signs shows that most of them exist in our real life and are closely related to our daily life. It can be roughly divided into three categories: first, domestic animals tamed by human beings: horses, sheep, pigs and so on. Second, we are familiar with animals: tigers, snakes, mice and so on. Thirdly, it is the mascot of China mythology-the dragon, which can be said to combine the advantages of most animals.

There are twelve zodiac signs in China and constellations in the west. The earliest constellations originated in Babylon. At that time, there were fewer constellations, and they were not used for naming and measuring luck at first. At first, the Babylonians divided the sky into many areas and named the known areas for calculating time. Constellations are mainly people-centered and divided by the trajectory of the sun.
