Who is more scientific, the lunar calendar or the Gregorian calendar? Who is the more suitable time for the earth to go around the sun?

The Gregorian calendar is a solar calendar, based on the time that the earth goes around the sun once. The lunar calendar is roughly based on the time when the moon revolves around the earth. The lunar calendar belongs to a kind of lunar calendar, and an average calendar month is equal to a new moon. However, the leap month is set to make the average calendar year a tropic year, and the 24 solar terms are set to reflect the changing characteristics of the seasons (the annual movement of the direct point of the sun), so there is also a solar calendar. Today, almost all Chinese in the world, as well as countries such as North Korea, South Korea, Vietnam and early Japan still use the lunar calendar to calculate traditional festivals such as Spring Festival, Mid-Autumn Festival and Dragon Boat Festival. The predecessor of Gregorian calendar is julian calendar revised by Caesar in ancient Rome. According to the regulations of julian calendar, there are 1 leap year every four years, with 366 days in leap year and 365 days in other three years (called average years). A leap year is a year in which the number of AD years can be divided by 4. The average length of julian calendar 1 year is 365.25 days, which is about 3 days longer than the actual 365.2422 days in period of revolution 1 1 minute 14 seconds, that is, every 400 years. In this way, by the time of16th century, the error of 10 day had been accumulated. You can obviously feel that there are two or two points ahead of schedule. In this case, Pope Gregory XIII announced the change of the calendar in 1582. First, the second day of julian calendar 1582 10/0/0/4 October was designated as Gregorian calendar 10/0/0 month 15, and 10 day was skipped. At the same time, julian calendar's leap rule was revised. Except leap years are reserved when the number of years in julian calendar is divided by 4. Added the rule that what is divided by 100 but not by 400 is not a leap year. This practice can reduce three leap years in 400 years. In the Gregorian calendar, there are 97 leap years (366 days per year) and 303 average years (365 days per year) in 400 years, so the average length of each year is 365.2425 days, which is very close to period of revolution. It is basically guaranteed that the error will not exceed 1 day before 5000 AD.
