What's the difference between ancient and modern astronomical calendars in China?
China ancient astronomical calendar is a calendar based on the observation of stars and astronomical phenomena by ancient astronomy, ancient mathematics and other ancient sciences, which summarizes the laws and applies them to production and life. The ancient astronomical calendar includes not only the observation of stars, but also astronomy and stars, yin and yang and five elements. The astronomical calendars in ancient China also studied the movements of the sun and the moon, and thus summed up calendars such as the lunar calendar and the solar calendar, as well as the solar orbit, which is what we usually call the ecliptic. Not only that, the ancient astronomical calendar also includes twenty-four solar terms, the zodiac and its branches, the precession of the Yin and Yang calendars and so on.
02. Modern astronomical calendar
Modern astronomical calendar is a more scientific astronomical calendar based on the ancient astronomical calendar, which has been systematically studied and sorted out by modern science and summarized and calculated by scientists. Modern astronomical calendars still include astrology, astronomical observation and prediction, and research in the fields of conventional tropical years, and even on this basis, more detailed star research has been started to predict the climate for national defense and life.
03. The difference between the two
The ancient astronomical calendar in China can accurately calculate whether the movements of the sun, the moon and other stars are beneficial to human survival, but relatively speaking, the modern calendar was created in a modern society with highly developed science and technology. Compared with ancient times, modern calendars are not only more systematic and complete in science and technology, but also more accurate in various measuring tools and astronomical instruments, so modern astronomical calendars can accurately calculate and predict what people want.
Although the ancient astronomical calendar in China is scientific and effective, compared with the modern astronomical calendar, there are still feudal superstitions, and astrology is a good example. The ancients corresponded the regions in the sky with the states and countries on the ground. When the ancients found that the astronomical phenomena in a certain area changed, they directly predicted good or bad luck corresponding to the relative areas on the ground.
In addition to calculation and science, modern astronomical calendars are more concise and easier for people to understand.
