Not only compiling the almanac, but also forecasting the orbit of the big planets
The current Chinese lunar calendar is compiled by the Department of calendar calculation and astronomical reference of Nanjing Zijinshan Observatory, which is the official publishing agency of the lunar calendar.
"The calendar calculation room is a department of Nanjing Zijinshan Observatory, which was established very early. At present, there are 10 staff members. Making the lunar calendar is actually part of our daily work. "Fu Yanning said that before calculating the lunar calendar, a precise computer is essential to do a lot of preparatory work.
'now we use computer models to calculate the lunar calendar. For example, calculating the position of celestial bodies is a standard model of the International Astronomical Union. It's a quick process to use the model to calculate the lunar calendar. He said that the current calculation method is relatively accurate, and there are still errors, so we need to constantly improve the model.
In addition to the compilation of the lunar calendar, their work ranged from the issuance of the standard lifting time of the national flag of the people's Republic of China, the accurate time of the total solar eclipse, to the scientific calculation of the sunshine time. In addition, it is also important to observe the movement of celestial bodies to improve the model.
Fu Yanning said that at present, the calendar calculation room can not only compile the annual calendar independently, but also accurately calculate the direction and speed of the sun, moon and other celestial bodies, and predict various kinds of astronomical phenomena. The calendar room also publishes the specific time (accurate to minutes) of 24 solar terms, the time of important astronomical phenomena (solar eclipse, etc.), the orbit of large planets, etc. every year.
The national standard of Lunar calculation is being worked out
The origin of China's calendar dates back to the legend era, and the establishment period began in the Warring States period. The four calendars in the Warring States period are all embodied in the ancient six calendars contained in the annals of art and culture of Hanshu middot. They are the oldest calendars in China.
However, Fu Yanning said that in the development of modern astronomy, the old China was far behind the western countries. Before 1970, the calendars published in China were mainly translated from the Soviet Union and European and American calendars.
In 1964, Zijinshan Observatory achieved initial success in independent calculation. In 1965, the quality of calculation was further improved. Later, Zijinshan Observatory compiled two astronomical calendars of China in 1969 and 1970 in a short time. In the preface of the 1970 astronomical calendar published by Science Press, it said: 'the birth of the Chinese astronomical calendar shows that the era of relying on the & lsquo; foreign calendar & rsquo; has gone forever. '
In Fu Yanning's view, the lunar calendar is essential for Chinese people, and its existing significance is embodied in cultural value. "The lunar calendar involves the calculation and determination of major holidays in China, such as the Spring Festival, the Mid Autumn Festival and the Qingming Festival, and is also an important basis for guiding agricultural activities.".
He said that at present, the calendar calculation office is preparing the national standards for the calculation of the lunar calendar and unifying the calculation methods. 'it can't be said that you are celebrating the new year today, but he is celebrating the new year tomorrow. We need a standard, that is, how to calculate the lunar calendar. Fu Yanning said that with the accumulation of extensive and high-precision astronomical observation data, the work of the calendar room of Zijinshan Observatory has been expanding. In the future, the lab will focus on the world, carry out scientific research with international level and carry out frontier research.
The calendar calculation room cannot be compared with the ancient imperial court
Fu Yanning revealed that because of the special political meaning of the calendar, there were often rulers in different dynasties who revised it to establish their own ruling authority.
The ancient calendar is not only for calculating dates and guiding agriculture, but also has important political meanings. It also determined that the calendar calculation room could not be compared with the imperial Tianjian in ancient times'. Fu Yanning introduced that according to the historical responsibility, the institution responsible for timing is the imperial Tianjian, which is the statutory calendar organization.
'we are totally different from the concept of the Qin Tianjian. Qin Tianjian served the emperor. We just worked out the lunar calendar. "He said that in ancient times, the emperor was regarded as the son of heaven, and the seasons were the will of heaven." the emperor should be familiar with the changes of the sky. If the emperor can't understand the will of heaven, how can he prove the authority of the rule? "
Fu Yanning said that in addition, many astronomical phenomena in ancient times, such as solar eclipse and lunar eclipse, were regarded as a warning to the world from heaven; important ceremonies and sacrificial ceremonies of the dynasty were usually carried out with reference to specific solar terms.
He said that the ancient calendar, to some extent, means the ruling power itself. The emperor promulgated the calendar to show the legitimacy of his regime; the people accepted the calendar to represent his recognition of the legitimacy of the regime.
The lunar calendar is not the lunar calendar
It's the combination of yin and Yang
'many people think that the lunar calendar is the lunar calendar, which is not the case. Fu Yanning introduced that the lunar calendar, also known as the Chinese calendar, the Chinese calendar and the national calendar, is the traditional Chinese calendar, which actually belongs to the yin-yang calendar.
