Is the constellation division calculated according to the date on the ID card?

It feels like it's calculated according to the date on the ID card.

Since ancient times, human beings have associated three or five stars with their mythical figures or artifacts, which are called "constellations". Constellation is a means to determine the orientation of the sky in almost all civilizations and is widely used in the field of navigation. The division of constellations is completely artificial, and different civilizations have different divisions and names.

Constellations have no uniform and precise boundaries. Until 1930, in order to unify the complicated constellation division, the International Astronomical Union divided the sky into 88 official constellations with precise boundaries, so that every star in the sky belonged to a specific constellation. Most of these official constellations are based on ancient Greek myths handed down from the Middle Ages.

The symbol of Aries symbolizes the head of the sheep, which is a pictographic method to take out the most obvious horns and noses of the sheep; Some characteristics can be associated with the myth of Aries, such as impulsiveness, freedom and courage. On the other hand, it also points out that the symbol of Aries is a green bud symbolizing rebirth, showing a scene of rebirth and prosperity.

The symbol of Gemini symbolizes twins, which is more abstract than the first two symbols. From the myth of Gemini, we can know the duality and internal contradictions of Gemini. In fact, Gemini represents not only duality, but so-called pluralism. On the one hand, it can be seen that it is wide, on the other hand, it also implies possible superficiality.
