How to make perpetual calendar single chip microcomputer

The perpetual calendar can display the year, month, day, 24 solar terms, lunar calendar and so on, and the single chip microcomputer is a chip. The perpetual calendar can be made by single chip microcomputer, but I really don't know how to do it by single chip microcomputer. I think what you want to ask is how to make a perpetual calendar with a single chip microcomputer, and I provide ideas.

1, the minimum system of single chip microcomputer. You can use STC89C52 chip+peripheral circuit. You can burn the programs written by users and realize the logic needed by perpetual calendars.

2. The real-time clock circuit can use DS 1302 chip. Provide year, month, day, hour, minute and second data to single chip microcomputer.

3. A display circuit. Used to display these data.

4. Some necessary buttons are used to adjust the data.
