What is the lunar calendar?

The lunar calendar, as its name implies, was born in farming or a calendar to facilitate agricultural production.

The lunar calendar is a calendar based on the lunar calendar (summer calendar) and integrating the solar calendar. So the lunar calendar is a combination of yin and yang.
