Are the lunar calendar and the lunar calendar the same thing?

Lunar calendar is one of the traditional calendars in China, also known as lunar calendar, ancient calendar, Han calendar, yellow calendar, summer calendar and old calendar. In astronomy, it mainly refers to the calendar arranged according to the moon phase cycle, in which the moon orbits the earth once, taking the sun as the reference object, and the actual moon runs for more than one week. It is January, that is, the calendar with 12 calendar months a year based on the first month of the lunar calendar.

In the process of calendar development and evolution, the emergence of 24 solar terms was used to scientifically guide agricultural production, and the lunar calendar (Han calendar) was formed. Although the lunar calendar and lunar calendar are commonly known as ancient calendar, Han calendar, summer calendar and old calendar, there are still differences between lunar calendar and lunar calendar (Han calendar). The traditional summer calendar (Han calendar) is actually a kind of yin-yang calendar.

Calendar introduction:

Calendar is based on the natural law of astronomical changes, to measure a long time interval, to judge the climate change, and to predict the coming season. According to the calendar year and month, it is divided into solar calendar, lunar calendar and yin-yang calendar. There are three kinds of calendars: lunar calendar, solar calendar and yin-yang calendar. In the lunar calendar, its basic calendar rules have been gradually improved and formed by generations, and its form has continued to this day. Lunar calendar is a calendar based on lunar calendar and solar calendar.

The lunar calendar is based on the lunar calendar (summer calendar), combined with the components of the solar calendar, absorbing the 24 solar terms of the solar calendar as a supplement, and adjusting it by leap method to make it conform to the tropic of cancer. Because it absorbs the 24 solar terms in the calendar, it can reflect the changes of seasons and guide agriculture and other things. Therefore, the lunar calendar has both lunar and solar elements. The lunar calendar is a combination of yin and yang, which refers to a calendar that takes into account the relationship between the sun, the moon and the earth.
