【正文】 design made Mega16 as the core controller, the peripheral circuits, including liquid crystal display module, clock module, the keyboard module and alarm module. Software with C language programming , achieves all functions of design. This calendar will not only show the number of points, the second, year, month, day, and have the following functions: display Chinese, the alarm time set, alarm clock, music selection, the whole point of time and free to adjust the time after power outages. The design of hardware circuits is simple, difficult in the Chinese public conversion, the design has been tested after the pletion of the basic functions to achieve the abovementioned Key words：
