Constellations are calculated according to the solar calendar, but why do I feel that the constellations compared with the solar calendar are nothing like mine?

The constellation comes from the west, so it is natural to use the Gregorian calendar. There is nothing to say about this, but there is no need to say that personality is not accurate, because generally astrology looks at personality. I think your understanding of the constellation is only in the sun constellation, and you don't have a deep understanding. The sun looks at a person's external personality, and the moon looks at a person's internal emotions. Ascension is a person's mask, and a person's view of love depends on his Venus.
