How to distinguish the lunar calendar from the solar calendar?

The Gregorian calendar is called the Gregorian calendar, which is based on the time when the earth revolves around the sun for one year. Now the international Gregorian calendar is Gregorian calendar. The full name of the lunar calendar is the lunar calendar, which is based on the cycle of the moon orbiting the earth. The so-called hijri calendar used in Arabic history books is actually the lunar calendar. The lunar calendar that China is talking about now is actually a combination of yin and yang, which not only takes care of the changes of the moon's profit and loss, but also takes care of the cold and summer solar terms. Because there are solar terms changes in the calendar, which are closely related to agricultural planting activities, the "Lunar Calendar" plays an important role in the lives of China people, especially farmers. It is not only a calendar, but also the embodiment of thousands of years' life experience and wisdom of China people.
