Why is the perpetual calendar produced by each manufacturer different?

The perpetual calendars produced by each manufacturer are different, which is the result of different basis, methods and bibliography for choosing auspicious days.

Gregorian calendar is the best carrier for choosing auspicious days. In order to facilitate people to choose auspicious days, the contents of choosing auspicious days in the past were all compiled by the state, so the conclusion of choosing auspicious days is the same.

After the founding of People's Republic of China (PRC), China's calendar was compiled by the state, but the state did not compile some auspicious contents. Before the reform and opening up, the calendar did not list auspicious content; After the reform and opening up, various publishing houses have included the contents of auspicious elections in their calendars. Because the publishers organize their own personnel to compile the contents of Lucky Selection, the differences in basis, methods and bibliography will inevitably lead to different conclusions of Lucky Selection.

With the development of science and technology, in order to facilitate the people, the perpetual calendar has now been made into an electronic version, that is, an electronic perpetual calendar. People can also use Baidu to search for "perpetual calendar" at any time.
