Why are there differences between lunar and solar calendars on the calendar?

The calendar is supposed to be convenient, so why is there such a cumbersome distinction between solar and lunar calendars?

There are many methods of chronology in various countries around the world, including the stem and branch chronology, the Taoist calendar, the imperial chronology, the astronomical chronology, the historical chronology, etc.

In addition, there are Buddhist chronology, Islamic chronology, Jewish chronology, Japanese chronology, Greek chronology, etc.

In China, we had our own calendar as early as 4000 BC.

Starting from the Yellow Emperor's calendar, for a long historical period, China used the "stem and branch calendar method", that is, the ten heavenly stems and the twelve earthly branches were combined respectively, and every 60 years was a cycle.

Since the starting point of the AD chronology is AD 1, most scientists who have a full understanding of the AD chronology and most authoritative astronomical institutions in the world clearly support the statement that the 21st century began in 2001.

Let’s focus on why there is such a cumbersome distinction between solar and lunar calendars?

The lunar calendar is one of the traditional Chinese calendars, also known as the Yin calendar, the ancient calendar, the Han calendar, the Xia calendar and the old calendar.

Strictly speaking, my country's traditional calendar should not be called the lunar calendar. It is a lunisolar calendar, which is now called the "Lunar Calendar". To be precise, it should be called the "Han Calendar".

Everyone, the name of the lunar calendar is based on the rules of the "Han Calendar" proposed by Emperor Wu of the Han Dynasty, and the name of this calendar in the "Complete Collection of Han Calendar" compiled by Emperor Kangxi of the Qing Dynasty. This calendar has been called since ancient times.

It is the "Han calendar".

The Han calendar uses the method of setting leap months and twenty-four solar terms to make the average length of the calendar year equal to the tropical year, so that it has the elements of the solar calendar.

From this perspective, the Han calendar has its advantages.

It better coordinates the cycles of the sun and the moon and achieves the unity of yin and yang. It is one of the most scientific astronomical calendars in the world.

Okay, now that we’ve introduced the lunar calendar, let’s introduce the solar calendar.

Our country began to adopt the Gregorian calendar in 1912.

The year after the Revolution of 1911 (1912), the then government of the Republic of China adopted the Gregorian calendar as the national calendar. In terms of chronology, the AD chronology was parallel to the Republic of China chronology.

On September 27, 1949, as approved by the First Plenary Session of the Chinese People's Political Consultative Conference, New China used the Gregorian calendar and the AD common to most countries in the international community as its calendar and calendar.

However, the lunar calendar has not been abolished. Today's traditional Chinese festivals are still based on the lunar calendar.
