Which is more accurate, the sun sign or the moon sign?

Hello, the constellation comes from the west. There is no lunar calendar in the west, but there is a lunar calendar in the east. Constellations are calculated according to the solar calendar, and the constellations are also very detailed. For example, there are sun constellations, moon constellations and rising constellations. Usually according to the solar calendar, it is a sun sign. If you want to know more, it is better to arrange an astrolabe in more detail. I hope my answer can help you. I hope it will be adopted. Thank you.
