How to divide calendars into solar calendars and lunar calendars?

The differences between the solar calendar and the lunar calendar are as follows:

The Gregorian calendar is the Gregorian calendar: we mainly use the internationally used calendar, namely the Gregorian calendar. It takes a tropical year as a year and then divides it into twelve months (the number of months is 3 1 day, 30 days and 29 days, all of which are manually designated), which is called the solar calendar, that is, the solar calendar.

In addition to the Gregorian calendar, China also retains the calendar that has been used since the Xia Dynasty: the summer calendar, which takes the period of twelve moons revolving once as a year, so that the time of a year is ten days less than that of a tropical year. Therefore, putting leap in the grid is called the lunar calendar (the moon is called the lunar calendar). It also contains calendar knowledge such as 24 solar terms, which is closely related to agricultural production, so it is also called lunar calendar.
