What's the difference between lunar calendar, solar calendar, yellow calendar, summer calendar and Gregorian calendar?

Lunar calendar is the same as lunar calendar and summer calendar, but there are two different versions, namely, what is the first day of the month, solar terms and so on, which are arranged according to the usual calendar in ancient China-heavenly stems and earthly branches.

Now our officials often use Gregorian calendar and Gregorian calendar. For example, it's August 5, 20 10, which is the Gregorian calendar.

The Gregorian calendar is based on the lunar calendar in China, and there are many calendars indicating the good or bad luck of a day.
