Why is there a difference between the solar calendar and the lunar calendar on the calendar?

Because both the solar calendar and the lunar calendar are universal in our country.

1. The 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.

Strictly speaking, the traditional calendar in China should not be called the lunar calendar. It is a kind of lunar calendar, which is now called "lunar calendar", or more precisely "Han calendar". (This title is based on the rules of the Han Calendar proposed by Emperor Wu of the Han Dynasty and the title of this calendar in the Imperial System of Emperor Kangxi of the Qing Dynasty. This calendar has been called the "Han Calendar" since ancient times. )

The "Han Calendar" adopts the method of setting leap month and 24 solar terms, so that the average length of the calendar year is equal to the tropic year, so there is an element of the solar calendar. From this perspective, the Han calendar has its advantages. It is one of the scientific astronomical calendars in the world, which well coordinates the cycles of the sun and the moon and realizes the integration of yin and yang.

2. China adopted the solar calendar from 19 12. The year after the outbreak of the Revolution of 1911 (19 12), the then government of the Republic of China adopted the Gregorian calendar as its national calendar. In chronology, the chronology of the AD is parallel to that of the Republic of China.

1949 On September 27th, the first plenary session of China People's Political Consultative Conference passed that the newly established People's Republic of China (PRC) adopted the Gregorian calendar and the Gregorian calendar year commonly used by most countries in the international community. However, the lunar calendar has not been abolished. Today, traditional festivals in China are based on the lunar calendar.

There are many methods of chronology in countries all over the world, such as Ganzhi Chronology, Taoism Chronology, Emperor Chronology, Astronomy Chronology, History Chronology and so on. In addition, there are Buddhist chronology, Islamic chronology, Jewish chronology, Japanese chronology, Greek chronology and so on.

In China, as early as 4000 BC, it had its own calendar. From the day of the Yellow Emperor, in a long historical period, China used the "chronology of trunk branches", that is, the ten-day trunk and the twelve-day branch were combined separately, and every 60 years was a cycle. Up to now, (20 18) is the traditional calendar of China kaiyuan 47 15.

Since the starting point of the year is 1, most scientists who have a full understanding of the year and the most authoritative astronomical institutions in the world clearly support the statement that 2 1 century began at 200 1.
