When did China begin to use the solar calendar?

1, lunar calendar first. From the development history of calendars, all countries with ancient cultures, such as Egypt, Babylon, India, Greece, Rome and China, initially used the lunar calendar.

China had its own calendar as early as 4000 BC. 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.

2. China adopted the solar calendar from 19 12. In the second 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 terms of chronology, the chronological method of the AD and the chronological method of the Republic of China go hand in hand.

1On September 27th, 949, with the approval of the first plenary session of China People's Political Consultative Conference, the newly established People's Republic of China (PRC) adopted the Gregorian calendar and AD calendar commonly used in most countries in the world. However, the lunar calendar has not been abolished. Today, traditional festivals in China are still based on the lunar calendar.

Extended data

During the Republic of China, there were two sets of calendars, one was the solar calendar and the other was the lunar calendar. It turns out that since the Revolution of 1911, the new southern government has mainly promoted the solar calendar and abolished the lunar calendar. By 1928, the Northern Expedition was won, the warlords fell, the Kuomintang basically unified the north and the south, and the slogan of abolishing the lunar calendar was even louder. Senior leaders and new school people regard the lunar calendar and all traditional festivals as feudal symbols and stumbling blocks to social progress, insist on cleaning them up, and even issue a "red-headed document" prohibiting everyone from celebrating festivals according to the lunar calendar, and all festivals should be celebrated according to the solar calendar.

However, documents belong to documents, and tradition belongs to tradition. A few new schools celebrate New Year's Day. Most old people still celebrate New Year's Day on the first day of the first month. Some friends are neither old nor new. New Year's Day is also Spring Festival, Spring Festival or Spring Festival. We have to worship our ancestors twice a year, put up two sets of Spring Festival couplets and give out two rounds of lucky money. This was a great spectacle in the Republic of China, and now we can't see it.
