Why doesn't the mobile calendar show the lunar calendar?

Please check whether the mobile phone has the function of displaying the lunar calendar date. If so, please check in the settings. If you don't have this function, I suggest you download it yourself.

Lunar calendar is a calendar used in parallel with Gregorian calendar in China at present. People used to call it the "lunar calendar", but it is actually a kind of lunar calendar, that is, the summer calendar, rather than the real "lunar calendar". People often call the summer calendar "lunar calendar" because the 24 solar terms are of great significance to agricultural production, but they are determined according to the position of the sun on the ecliptic and belong to the solar calendar. Today, almost all Chinese in the world, as well as countries such as North Korea, South Korea, Vietnam and early Japan still use the lunar calendar to calculate traditional festivals such as Spring Festival, Mid-Autumn Festival and Dragon Boat Festival.

People think that the twenty-four solar terms are of great significance to agricultural production, so they often refer to the Han calendar as the "lunar calendar", but the twenty-four solar terms should be determined according to the position of the sun on the ecliptic and belong to the solar calendar. Therefore, it is not appropriate to call the Han calendar the lunar calendar.

Twenty-four solar terms originated in the Yellow River Basin. As early as the Spring and Autumn Period, four solar terms were set, namely, mid-spring, mid-summer, mid-autumn and mid-winter. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established. In BC 104, the taichu calendar written by Deng Ping officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms.
