Which is more accurate, solar calendar or lunar calendar?

Constellation originated from western astrology, and the calendar used in the west is solar calendar, so it is solar calendar, that is, the date that passes quickly. The twelve constellations come from the west. Because the west divides regions according to the constellations determined by the solar calendar, the constellations are calculated according to the solar calendar.

Secondly, the lunar calendar cannot mark seasons, and the 24 solar terms are a calendar system separated from the lunar calendar like the summer solstice. This is a pure solar calendar.
