What is the calendar of the Ming Dynasty?

Calendar name. Liu Dali in the early Ming Dynasty. In the seventeenth year of Hongwu, an observatory was set up in Jiming Mountain, which made Dr. Tong Yuan modify his calendar, still under the name of "Datong". The integrals are all about the figures of "timing" in the Yuan Dynasty, except its growth and decline. Later, due to the inaccurate calculation of solar eclipse, calendar managers flocked to ask for a new calendar, but the big calendar was always used in the Ming Dynasty. See Ming History.
