Where is the most accurate solar term?

Hello, Gregorian calendar is the calendar of western countries, which was introduced to China only in the last 100 years, and solar terms were passed down in China for 5,000 years. It can be said that the Gregorian calendar has nothing to do with solar terms, totally irrelevant.

Both the solar calendar and the lunar calendar are calendars, and no one is more accurate between them, but the calculation methods are different.

Just as computers and abacus are more accurate, it doesn't make any sense.
