包括日期日历以及学生成绩统计，应该能用吧，可以试下，这些不是单片机完成的！-Including the date, calendar, and student performance statistics, it should can be used , you can try, these are not completed by MCU!

用51单片机实现万年历的编程，用1602显示-Programming of the MCU 51 calendar display with 1602

这个是利用51单片机做的一个万年历有阴历阳历，并且含有电路图Preotl 99se对于学习和做毕业设计比较适合-This is done by 51 MCU a calendar lunar solar calendar, and contains the circuit diagram Preotl 99se more suitable for learning and doing graduate design

1602课设，简单实用，采用89c51的mcu，1602显示屏，显示万年历，具有农历显示，闰年补偿，报时等功能(1602 courses, simple and practical, the use of 89C51 MCU, 1602 display, display calendar, with lunar calendar, leap year compensation, time and other functions)
