Does 28 mean 28?

Twenty-eight is the twenty-eighth day of the lunar calendar, which is what our elders call the first day of the first month. At present, China Lunar Calendar and Gregorian Calendar are used in parallel. People are used to calling it "the lunar calendar", but it is actually a lunar calendar, that is, the summer calendar, rather than the real "lunar calendar".

Because the twenty-four solar terms are of great significance to agricultural production, people often refer to the summer calendar as the "lunar calendar", but the twenty-four solar terms are determined according to the position of the sun on the ecliptic and belong to the solar calendar. All China people in the world, such as North Korea, South Korea, Viet Nam and early Japanese, still use the lunar calendar to calculate traditional festivals such as Spring Festival, Mid-Autumn Festival and Dragon Boat Festival.

Calendar is a law that measures long time intervals, judges climate change and predicts the coming of seasons according to the natural laws of astronomical phenomena. According to calendar year, calendar year and calendar month, it can be divided into ephemeris, solar calendar, lunar calendar and combined calendar of yin and yang. It is a kind of calendar, which is formed on the basis of combining the lunar summer calendar with the solar calendar.
