When did the zodiac and the zodiac originate respectively? Which is more accurate? Is it different from person to person?

What problem? Do you mean the origin of the moon? Or where did they come from?

The zodiac is China's (according to the lunar calendar).

The twelve constellations are foreign (according to the new calendar)

If it's just for fun, then watch the twelve constellations.

If you are from China, it is more accurate to use the zodiac to calculate. But this thing is not as simple as simple calculation.

Daoism should be used for calculation. I suggest you go to the voice of Taoism.
